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 three months ended January 31, 2015, as compared to the significant accounting policies disclosed in Brocade’s Annual Report on Form 10-K for the fiscal year ended November 1, 2014. New Accounting Pronouncements or Updates Recently Adopted In March 2013, the Financial Accounting Standards Board (“FASB”) issued an update to Accounting Standards Codification (“ASC”) 830, Foreign Currency Matters: 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 the entity ceases to have a controlling financial interest resulting from the complete or substantially complete liquidation of a subsidiary or group of assets within a foreign entity. This update should be applied prospectively. The Company adopted this update in the first quarter of fiscal year 2015. There was no material impact on its financial position, results of operations, or cash flows. Recent Accounting Pronouncements or Updates That Are Not Yet Effective In April 2014, the FASB issued an update to ASC 205, Presentation of Financial Statements, and ASC 360, Property, Plant, and Equipment: 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 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. The Company is currently evaluating the impact of this update on its consolidated financial statements. In May 2014, the FASB issued an update to ASC 606, Revenue from Contracts with Customers, 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 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 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. Cash and cash equivalents are primarily maintained at five 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 January 31, 2015, one customer individually accounted for 24% of total accounts receivable and no other customers exceeded 10% of total accounts receivable. As of November 1, 2014, three customers individually accounted for 15%, 12%, and 11% of total accounts receivable, for a combined total of 38% 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 January 31, 2015, three customers individually accounted for 20%, 14%, and 10% of the Company’s total net revenues for a combined total of 44% of total net revenues. For the three months ended January 25, 2014, four customers individually accounted for 18%, 18%, 11%, and 10% of the Company’s total net revenues for a combined total of 57% 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 multiple contract manufacturers (“CMs”) for the production 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 components used in the manufacture of products from single or limited supplier sources.
