Each NAS Blade is comprised of 1 NAS server board with 2 1Gigabit Ethernet ports, for a total of 4 Ethernet ports per NAS Cluster. <> <> The NAS software components included the NAS operating system, protocol components (NFS, CIFS, DNS, NIS, HTTP, etc), NAS management, failover, and backup software. <> <> Disk Configuration: <> 128 total disks (Hitachi 72GB 10k RPM) on the 9980V were configured as 32 RAID Level 0+1 (2+2) LUNS. RAID 0+1 is a mirrored pair (RAID-1) made from two stripe sets (RAID-0). <> A total of 32 LUNs were mapped as file systems (fs00, fs01, .., fs31) via the NAS configuration management software and presented across 8 NAS Ethernet ports (1 Ethernet port per NAS Blade) to the Cisco 6506 and load generating clients. <> <> NVRAM and Memory: <> Total Memory of 154800MB consists of 9980V Cache (126976MB) and Lightning NAS Blade Embedded Cache (27824MB total for all 8 NAS Blades (3478MB per NAS Blade)). Note: Additional 9980V Cache was installed for this Lightning NAS Blade - 4 Cluster Configuration. <> 9980V configured with 124GB (126976MB) memory as disk cache, installed with battery backup to flush all cache data to disk in the event of a power loss. <> <> UPS: <> The power source for the NAS Blade emedded cache is the same as for the Hitachi Lightning 9900 Storage Subsystem cache, which utilizes battery backup. <> <> Testing Parameter Modifications: <> UDP Protocol (NFS=0), PROCS=128. <> Kernel system trace of NAS engine (linux based OS) is restrained. <> "noatime" and "wsync" options on the linux based OS are specified as valid when mounting the file system. <> <> Network Configuration: <> Ethernet connections to Cisco 6506 from Lightning NAS blades via 1000Base-SX. <> Each NAS Blade is capable of supporting 2 Ethernet ports (total of 16 Ethernet ports). Only 1 Ethernet port per NAS Blade (total of 8) were utilized during testing. <> Ethernet connections to 8 clients was via CAT-5 copper. =============================================================================== Generated on Thu Apr 14 14:55:27 EDT 2005 by SPEC SFS97 ASCII Formatter Copyright (c) 1997-2004 Standard Performance Evaluation Corporation
