Appl. No.:

8/715183

Inventors:

Robert N. Mastors - Colorado Springs CO

Assignee:

Sun Microsystems, Inc. - Palo Alto CA

International Classification:

G06F 1214

US Classification:

39520033

Abstract:

Apparatus and a method for a client/server computing system having an optimized log file system for replaying client disconnect write operations to a server when the server becomes available to the client. Data in the unauthorized disconnect write operations to a target file at the client are prevented from being copied to the server when the server becomes available. When there is a write request for a target file at the client, and the client detects the target file has already been written, the credentials with the write request are compared to the store credentials from a previous write to the same target file. If the request credentials are the same as the stored credentials, data from the write request is written to the target file effectively adding more data to the target file. If the request credentials are not the same as the stored credentials the write request is suspended at the client. When the client detects that the server is available, the stored credentials of the target file are retrieved from the credentials table, and the target file is sent along with the stored credentials to the server.

Abstract:

Described herein are enhancements for managing quality of service in a multi-host Peripheral Component Interconnect Express (PCIe) switching environment. In one implementation, a host system is configured to maintain quality of service statistics corresponding to data interactions with a PCIe storage device available via a PCIe switch. The host system may further receive secondary quality of service statistics for one or more other host systems communicatively coupled to the PCIe device via the PCIe switch, and determine a maximum queue depth for the host system based on the quality of service statistics and the second quality of service statistics to maintain a quality of service for the host systems.
