Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies There have been no material changes in the Company’s significant accounting policies for the six months ended May 3, 2014, as compared to the significant accounting policies disclosed in Brocade’s Annual Report on Form 10-K for the fiscal year ended October 26, 2013. New Accounting Pronouncements or Updates Recently Adopted In February 2013, the FASB issued an update to ASC 220: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. Under this update, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income (“AOCI”) into net income by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. The Company adopted this update in the first quarter of fiscal year 2014, presenting the required information in Note 12, “Accumulated Other Comprehensive Income (Loss),” of the Notes to Condensed Consolidated Financial Statements. Recent Accounting Pronouncements or Updates That Are Not Yet Effective In March 2013, the FASB issued an update to ASC 830 Foreign Currency Matters (“ASC 830”): Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity. Under this update, an entity is required to release any cumulative translation adjustment into net income when an entity ceases to have a controlling financial interest resulting in the complete or substantially complete liquidation of a subsidiary or group of assets within a foreign entity. This update to ASC 830 should be applied prospectively and will be adopted by the Company in the first quarter of fiscal year 2015. The Company does not expect the adoption of this update to ASC 830 to have a material impact on its financial position, results of operations or cash flows. In July 2013, the FASB issued an update to ASC 740 Income Taxes (“ASC 740”): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. Under this update, an entity is required to present an unrecognized tax benefit, or a portion thereof, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent that these instances are not available at the reporting date. This update to ASC 740 should be applied prospectively and will be adopted by the Company in the first quarter of fiscal year 2015. Early adoption and retrospective application are permitted. The Company does not expect the adoption of this update to ASC 740 to have a material impact on its financial position, results of operations or cash flows. In April 2014, the FASB issued an update to ASC 205 Presentation of Financial Statements (“ASC 205”) and ASC 360 Property, Plant, and Equipment (“ASC 360”): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. Under this update, a discontinued operation may include a component of an entity or a group of components of an entity, or a business or nonprofit activity. Only those disposals of components of an entity that represent a strategic shift that has, or will have, a major effect on an entity’s operations and financial results will be reported as discontinued operations in the financial statements. This update to ASC 205 and ASC 360 should be applied prospectively and will be adopted by the Company in the first quarter of fiscal year 2016. Early adoption is permitted, but only for disposals that have not been reported in financial statements previously issued. In May 2014, the FASB issued an update to ASC 606 Revenue from Contracts with Customers (“ASC 606”) that will supersede virtually all existing revenue guidance. Under this update, an entity is required to recognize revenue upon transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. As such, an entity will need to use more judgment and make more estimates than under the current guidance. This update to ASC 606 should be applied retrospectively either to each prior reporting period presented in the financial statements, or only to the most current reporting period presented in the financial statements with a cumulative effect adjustment recorded in the retained earnings. This update to ASC 606 becomes effective and will be adopted by the Company in the first quarter of fiscal year 2018. Early adoption is not permitted. The Company is currently evaluating the impact of this update on its consolidated financial statements. Concentrations Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents and accounts receivable. The Company’s cash and cash equivalents are primarily maintained at four major financial institutions. Deposits held with banks may be redeemed upon demand and may exceed the amount of insurance provided on such deposits. A majority of the Company’s accounts receivable balance is derived from sales to original equipment manufacturer (“OEM”) partners in the computer storage and server industry. As of May 3, 2014, three customers accounted for 15%, 11%, and 11%, respectively, of total accounts receivable, for a combined total of 37% of total accounts receivable. As of October 26, 2013, four customers accounted for 18%, 12%, 11%, and 11%, respectively, of total accounts receivable, for a combined total of 52% of total accounts receivable. The Company performs ongoing credit evaluations of its customers and generally does not require collateral on accounts receivable balances. The Company has established reserves for credit losses, sales allowances and other allowances. For the three months ended May 3, 2014, four customers accounted for 17%, 16%, 12%, and 11%, respectively, of the Company’s total net revenues for a combined total of 56% of total net revenues. For the three months ended April 27, 2013, three customers accounted for 18%, 16%, and 11%, respectively, of the Company’s total net revenues for a combined total of 45% of total net revenues. The Company currently relies on single and limited sources for multiple key components used in the manufacture of its products. Additionally, the Company relies on contract manufacturers (“CMs”) for the manufacturing of its products. Although the Company uses standard parts and components for its products where possible, the Company’s CMs currently purchase, on the Company’s behalf, several key product components from single or limited supplier sources.
