- Hitachi Data Systems' Lightning NAS Blade is a fully functional, fully featured clustered NAS server that is installed and integrated, as an option, into the Hitachi Lightning 9900™ V Series enterprise storage systems.
- Lightning NAS Blade - 2 Cluster Configuration:
- The tested configuration consisted of four Lightning NAS Blades (creating 2 NAS Clusters) installed into one Lightning 9980V storage system. 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 4 NAS Ethernet ports (1 Ethernet port per NAS Blade) to the Cisco 6506 and load generating clients.
- NVRAM and Memory:
- Total Memory of 79448MB consists of 9980V Cache (65536MB) and Lightning NAS Blade Embedded Cache (13912MB total for all 4 NAS Blades (3478MB per NAS Blade)). Note: Additional 9980V Cache was installed for this Lightning NAS Blade - 2 Cluster Configuration.
- 9980V configured with 64GB (65536MB) memory as disk cache, installed with battery backup to flush all cache data to disk in the event of a power loss.
- 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 8 Ethernet ports). Only 1 Ethernet port per NAS Blade (total of 4) were utilized during testing.
- Ethernet connections to 4 clients via CAT-5 copper.
