Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Significant Accounting Policies Principles of Consolidation The condensed consolidated financial statements of the Company have been prepared by management in accordance with accounting principles generally accepted in the United States of America (“GAAP”), applied on a basis consistent for all periods. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for a complete set of financial statements. These condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed with the Securities and Exchange Commission on May 13, 2020. In the opinion of management, all adjustments of a normal recurring nature considered necessary for a fair presentation have been included. The results of operations of any interim period are not necessarily indicative of the results of operations to be expected for the full fiscal year. These condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany balances and transactions have been appropriately eliminated in consolidation. Use of Estimates The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenues and expenses during the reporting period. Significant areas requiring the use of management estimates relate to the determination of provisions for impairment assessments of goodwill, other indefinite-lived intangible assets; revenue; allowance for doubtful receivables; inventory valuation; warranty provisions; and litigation claims. Actual results could differ from these estimates. Foreign Currency Translation The financial statements of foreign subsidiaries, for which the functional currency is the local currency, are translated into U.S. dollars using the exchange rate at the consolidated balance sheet date for assets and liabilities and a weighted-average exchange rate during the year for revenue, expenses, gains and losses. Translation adjustments are recorded as other comprehensive income (loss) within shareholders’ equity. Gains or losses from foreign currency transactions are recognized in the condensed consolidated statements of operations. Such transactions resulted in a loss of $8,000 and $5,000 in the three months ended September 30, 2020 and 2019, respectively, and a loss of $9,000 and $13,000 in the nine months ended September 30, 2020 and 2019, respectively. Cash Equivalents Highly liquid investments with insignificant interest rate risk and original maturities of three months or less, when purchased, are classified as cash equivalents. Cash equivalents are composed of money market funds. The carrying amounts approximate fair value due to the short maturities of these instruments. Accounts Receivable Accounts receivable is recorded at the invoiced amount and is non-interest bearing. We estimate our allowance for doubtful accounts based on an assessment of the collectability of specific accounts and the overall condition of the accounts receivable portfolio. When evaluating the adequacy of the allowance for doubtful accounts, we analyze specific trade and other receivables, historical bad debts, customer credits, customer concentrations, customer credit-worthiness, current economic trends and changes in customers’ payment terms and/or patterns. We review the allowance for doubtful accounts on a quarterly basis and record adjustments as considered necessary. Customer accounts are written-off against the allowance for doubtful accounts when an account is considered uncollectable. Inventories Inventories are stated at the lower of cost and net realizable value using the first-in-first-out method. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. We assess the value of inventories periodically based upon numerous factors including, among others, expected product or material demand, current market conditions, technological obsolescence, current cost, and net realizable value. If necessary, we write down our inventory for obsolete or unmarketable inventory by an amount equal to the difference between the cost of the inventory and the net realizable value. Investment in Affiliate The Company holds an investment in equity securities of a nonpublic company for business and strategic purposes. The equity securities do not have a readily determinable fair value and are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The Company reviews its investment on a regular basis to determine if the investment is impaired. For purposes of this assessment, the Company considers the investee’s cash position, earnings and revenue outlook, liquidity and management ownership, among other factors, in its review. If management’s assessment indicates that an impairment exists, the Company estimates the fair value of the equity investment and recognizes in current earnings an impairment loss that is equal to the difference between the fair value of the equity investment and its carrying amount. Goodwill and Intangible Assets Goodwill represents the excess of consideration paid over the value assigned to the net tangible and identifiable intangible assets acquired. For intangible assets purchased in a business combination, the estimated fair values of the assets received are used to establish their recorded values. For intangible assets acquired in a non-monetary exchange, the estimated fair values of the assets transferred (or the estimated fair values of the assets received, if more clearly evident) are used to establish their recorded values. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value. Purchased intangible assets are amortized on a straight-line basis over their economic lives of 15 years for supplier agreement, six to 25 years for channel partner relationships, three to nine years for developed technology, three to eight years for capitalized development costs, and two to 25 years for customer relationships as this method most closely reflects the pattern in which the economic benefits of the assets will be consumed. Impairment of Goodwill and Intangible Assets Goodwill and intangible assets are tested for impairment on an annual basis at December 31, or more frequently if there are indicators of impairment. Triggering events for impairment reviews may be indicators such as adverse industry or economic trends, restructuring actions, lower projections of profitability, or a sustained decline in our market capitalization. Intangible assets are quantitatively assessed for impairment, if necessary, by comparing their estimated fair values to their carrying values. If the carrying value exceeds the fair value, the difference is recorded as an impairment. Revenue Recognition The Company accounts for revenue pursuant to ASU 2014-09, Revenue from Contracts with Customers and all the related amendments (“Topic 606”). Under Topic 606, an entity is required to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services, and contract consideration will be recognized on a “sell-in basis” or when control of the purchased goods or services transfer to the distributor. The Company generates revenue primarily from: (i) solutions for standalone storage and integrated hyper-converged storage; (ii) professional services; and (iii) warranty and customer services. The Company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To determine revenue recognition for contracts with customers the Company performs the following five steps: (i) identify the promised goods or services in the contract; (ii) identify the performance obligations in the contract, including whether they are distinct in the context of the contract; (iii) determine the transaction price, including the constraint on variable consideration; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies the performance obligations. Approximately 70% of the Company’s revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied at a point in time. These contracts are generally comprised of a single performance obligation to transfer products. Accordingly, the Company recognizes revenue when change of control has been transferred to the customer, generally at the time of shipment of products. The Company sells its products both directly to customers and through distributors generally under agreements with payment terms typically less than 45 days. Revenue on direct product sales, excluding sales to distributors, are not entitled to any specific right of return or price protection, except for any defective product that may be returned under our standard product warranty. Product sales to distribution customers that are subject to certain rights of return, stock rotation privileges and price protections, contain a component of “variable consideration.” Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products and is generally based upon a negotiated fixed price and is net of estimates for variable considerations. For performance obligations related to warranty and customer services, such as extended product warranties, the Company transfers control and recognizes revenue on a time-elapsed basis. The performance obligations are satisfied as services are rendered typically on a stand-ready basis over the contract term, which is generally 12 months. In limited circumstances where a customer is unable to accept shipment and requests products be delivered to, and stored on, the Company’s premises, also known as a “bill-and-hold” arrangement, revenue is recognized when: (i) the customer has requested delayed delivery and storage of the products, (ii) the goods are segregated from the inventory, (iii) the product is complete, ready for shipment and physical transfer to the customer, and (iv) the Company does not have the ability to use the product or direct it to another customer. The Company also enters into revenue arrangements that may consist of multiple performance obligations of its product and service offerings such as for sales of hardware devices and extended warranty services. The Company allocates contract fees to the performance obligations on a relative stand-alone selling price basis. The Company determines the stand-alone selling price based on its normal pricing and discounting practices for the specific product and/or service when sold separately. When the Company is unable to establish the individual stand-alone price for all elements in an arrangement by reference to sold separately instances, the Company may estimate the stand-alone selling price of each performance obligation using a cost plus a margin approach, by reference to third party evidence of selling price, based on the Company’s actual historical selling prices of similar items, or based on a combination of the aforementioned methodologies; whichever management believes provides the most reliable estimate of stand-alone selling price. Warranty and Extended Warranty The Company records a provision for standard warranties provided with all products. If future actual costs to repair were to differ significantly from estimates, the impact of these unforeseen costs or cost reductions would be recorded in subsequent periods. Separately priced extended on-site warranties and service contracts are offered for sale to customers on all product lines. The Company contracts with third party service providers to provide service relating to on-site warranties and service contracts. Extended warranty and service contract revenue and amounts paid in advance to outside service organizations are deferred and recognized as service revenue and cost of service, respectively, over the period of the service agreement. The Company will typically apply the practical expedient to agreements wherein the period between transfer of any good or service in the contract and when the customer pays for that good or service is one year or less. Advanced payments for long-term maintenance and warranty contracts do not give rise to a significant financing component. Rather, such payments are required by the Company primarily for reasons other than the provision of finance to the entity. Research and Development Costs Research and development expenses include payroll, employee benefits, share-based compensation expense, and other headcount-related expenses associated with product development. Research and development expenses also include third-party development and programming costs. Comprehensive Income (Loss) Comprehensive income (loss) and its components encompass all changes in equity other than those arising from transactions with shareholders, including net loss and foreign currency translation adjustments, and is disclosed in a separate condensed consolidated statement of comprehensive loss. Share-based Compensation We account for share-based awards, and similar equity instruments, granted to employees, non-employee directors, and consultants under the fair value method. Share-based compensation award types include stock options and restricted stock. We use the Black-Scholes option pricing model to estimate the fair value of option awards on the measurement date, which generally is the date of grant. The expense is recognized over the requisite service period (usually the vesting period) for the estimated number of instruments for which service is expected to be rendered. The fair value of restricted stock units (“RSUs”) is estimated based on the market value of the Company’s common shares on the date of grant. The fair value of options granted to non-employees is estimated at the measurement date using the Black-Scholes option pricing model. Share-based compensation expense for options with graded vesting is recognized pursuant to an accelerated method. Share-based compensation expense for RSUs is recognized over the vesting period using the straight-line method. Share-based compensation expense for an award with performance conditions is recognized when the achievement of such performance conditions are determined to be probable. If the outcome of such performance condition is not determined to be probable or is not met, no compensation expense is recognized and any previously recognized compensation expense is reversed. Forfeitures are recognized in share-based compensation expense as they occur. We have not recognized, and do not expect to recognize in the near future, any tax benefit related to share-based compensation cost as a result of the full valuation allowance of our net deferred tax assets and its net operating loss carryforward. Recently Issued Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) that are adopted by the Company as of the specified effective date. If not discussed, the Company believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption. Recently Adopted Accounting Pronouncements In August 2018, the FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820) (“ASU 2018-13”). The new guidance removes, modifies and adds to certain disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. The update is effective for annual reporting periods, including interim periods, beginning after December 15, 2019. The adoption of the new standard did not have an effect on our financial position, results of operations or cash flows. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). The update simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, if applicable. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. The same impairment test also applies to any reporting unit with a zero or negative carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The update is effective for annual reporting periods, including interim periods, beginning after December 15, 2019, on a prospective basis. The adoption of the new standard did not have an effect on our financial position, results of operations or cash flows.

The condensed consolidated financial statements of the Company have been prepared by management in accordance with accounting principles generally accepted in the United States of America (“GAAP”), applied on a basis consistent for all periods. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for a complete set of financial statements. These condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, filed with the Securities and Exchange Commission on May 13, 2020. In the opinion of management, all adjustments of a normal recurring nature considered necessary for a fair presentation have been included. The results of operations of any interim period are not necessarily indicative of the results of operations to be expected for the full fiscal year. These condensed consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany balances and transactions have been appropriately eliminated in consolidation.

The preparation of the condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenues and expenses during the reporting period. Significant areas requiring the use of management estimates relate to the determination of provisions for impairment assessments of goodwill, other indefinite-lived intangible assets; revenue; allowance for doubtful receivables; inventory valuation; warranty provisions; and litigation claims. Actual results could differ from these estimates.

The financial statements of foreign subsidiaries, for which the functional currency is the local currency, are translated into U.S. dollars using the exchange rate at the consolidated balance sheet date for assets and liabilities and a weighted-average exchange rate during the year for revenue, expenses, gains and losses. Translation adjustments are recorded as other comprehensive income (loss) within shareholders’ equity. Gains or losses from foreign currency transactions are recognized in the condensed consolidated statements of operations. Such transactions resulted in a loss of $8,000 and $5,000 in the three months ended September 30, 2020 and 2019, respectively, and a loss of $9,000 and $13,000 in the nine months ended September 30, 2020 and 2019, respectively.

Highly liquid investments with insignificant interest rate risk and original maturities of three months or less, when purchased, are classified as cash equivalents. Cash equivalents are composed of money market funds. The carrying amounts approximate fair value due to the short maturities of these instruments.

Accounts receivable is recorded at the invoiced amount and is non-interest bearing. We estimate our allowance for doubtful accounts based on an assessment of the collectability of specific accounts and the overall condition of the accounts receivable portfolio. When evaluating the adequacy of the allowance for doubtful accounts, we analyze specific trade and other receivables, historical bad debts, customer credits, customer concentrations, customer credit-worthiness, current economic trends and changes in customers’ payment terms and/or patterns. We review the allowance for doubtful accounts on a quarterly basis and record adjustments as considered necessary. Customer accounts are written-off against the allowance for doubtful accounts when an account is considered uncollectable.

Inventories are stated at the lower of cost and net realizable value using the first-in-first-out method. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. We assess the value of inventories periodically based upon numerous factors including, among others, expected product or material demand, current market conditions, technological obsolescence, current cost, and net realizable value. If necessary, we write down our inventory for obsolete or unmarketable inventory by an amount equal to the difference between the cost of the inventory and the net realizable value.

The Company holds an investment in equity securities of a nonpublic company for business and strategic purposes. The equity securities do not have a readily determinable fair value and are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The Company reviews its investment on a regular basis to determine if the investment is impaired. For purposes of this assessment, the Company considers the investee’s cash position, earnings and revenue outlook, liquidity and management ownership, among other factors, in its review. If management’s assessment indicates that an impairment exists, the Company estimates the fair value of the equity investment and recognizes in current earnings an impairment loss that is equal to the difference between the fair value of the equity investment and its carrying amount.

Goodwill represents the excess of consideration paid over the value assigned to the net tangible and identifiable intangible assets acquired. For intangible assets purchased in a business combination, the estimated fair values of the assets received are used to establish their recorded values. For intangible assets acquired in a non-monetary exchange, the estimated fair values of the assets transferred (or the estimated fair values of the assets received, if more clearly evident) are used to establish their recorded values. Valuation techniques consistent with the market approach, income approach and/or cost approach are used to measure fair value.

Purchased intangible assets are amortized on a straight-line basis over their economic lives of 15 years for supplier agreement, six to 25 years for channel partner relationships, three to nine years for developed technology, three to eight years for capitalized development costs, and two to 25 years for customer relationships as this method most closely reflects the pattern in which the economic benefits of the assets will be consumed.

Goodwill and intangible assets are tested for impairment on an annual basis at December 31, or more frequently if there are indicators of impairment. Triggering events for impairment reviews may be indicators such as adverse industry or economic trends, restructuring actions, lower projections of profitability, or a sustained decline in our market capitalization. Intangible assets are quantitatively assessed for impairment, if necessary, by comparing their estimated fair values to their carrying values. If the carrying value exceeds the fair value, the difference is recorded as an impairment.

Advanced payments for long-term maintenance and warranty contracts do not give rise to a significant financing component. Rather, such payments are required by the Company primarily for reasons other than the provision of finance to the entity.

Research and development expenses include payroll, employee benefits, share-based compensation expense, and other headcount-related expenses associated with product development. Research and development expenses also include third-party development and programming costs.

Comprehensive income (loss) and its components encompass all changes in equity other than those arising from transactions with shareholders, including net loss and foreign currency translation adjustments, and is disclosed in a separate condensed consolidated statement of comprehensive loss.

We account for share-based awards, and similar equity instruments, granted to employees, non-employee directors, and consultants under the fair value method. Share-based compensation award types include stock options and restricted stock. We use the Black-Scholes option pricing model to estimate the fair value of option awards on the measurement date, which generally is the date of grant.

Share-based compensation expense for an award with performance conditions is recognized when the achievement of such performance conditions are determined to be probable. If the outcome of such performance condition is not determined to be probable or is not met, no compensation expense is recognized and any previously recognized compensation expense is reversed. Forfeitures are recognized in share-based compensation expense as they occur.

We have not recognized, and do not expect to recognize in the near future, any tax benefit related to share-based compensation cost as a result of the full valuation allowance of our net deferred tax assets and its net operating loss carryforward.

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) that are adopted by the Company as of the specified effective date. If not discussed, the Company believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption.

In August 2018, the FASB issued Accounting Standards Update (“ASU”) No. 2018-13, Fair Value Measurement (Topic 820) (“ASU 2018-13”). The new guidance removes, modifies and adds to certain disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. The update is effective for annual reporting periods, including interim periods, beginning after December 15, 2019. The adoption of the new standard did not have an effect on our financial position, results of operations or cash flows.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). The update simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, if applicable. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. The same impairment test also applies to any reporting unit with a zero or negative carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The update is effective for annual reporting periods, including interim periods, beginning after December 15, 2019, on a prospective basis. The adoption of the new standard did not have an effect on our financial position, results of operations or cash flows.
