Other Notes

The tested system was a cluster of two (2) BlueArc Titan 3110-F servers connected via Fibre Channel fabric to ten (10) storage arrays. Each array consisted of 1 BlueArc RC16TB (LSI 3992) Dual RAID controller with 64 FC drives. Each Dual RAID controller set has 2GB memory, for a total of 20GB cashe memory across all storage controllers. RAID controller cache memory is included in the 86GB memory size listed above.
The Titan server had all standard protection services enabled, including RAID, NVRAM logging, and media error scrubbing.
Titan 3110 uses 12 Field Programmable Gate Arrays (FPGAs) to accelerate processing of network traffic and file system I/O.
Disk drives used were 73GB, 15,000 RPM, 4GB-FC Seagate ST373455FC drives.
Disk and FS configuration was 32 "1+1" RAID-1 LUs per RAID Controller pair. Each RAID Controller pair represented one Storage Pool created by striping across the 32 LUs. (striping parameters are fixed and not under user control) Two file systems were created within each Storage Pool. The twenty (20) file systems were aggregated to a single namespace "/r" using BlueArc's Cluster Namespace (CNS) feature.
The storage arrays were connected to the Titan server using redundant Brocade 200E FC switches with dual redundant connections to each array.
The Titan 3110 server cluster is connected to 12 Load Generators via 10GigE (end to end) through a single Force10 S2410 switch.
For Uniform Access Rule compliance all LG's accessed all cluster namespace objects uniformly across all interfaces as follows:
- There is 1 network node (i.e., Titan 3110 server cluster): T0
- There are 20 physical target file systems (/r/f1…./r/f20) presented as a single cluster name space (F1) with virtual root “/r” accessible to all clients.
- Each Titan 3110 had a single Virtual Server configured, and each Virtual Server owned ten (10) of the twenty (20) total file systems in the cluster.
- Each Load Generator (1-12) mounted to each file system target (/r/f*) and cycled through the target file systems /r/f1, /r/f2, /r/f3, etc. in sequence.
Titan 3110 contains four modules that perform all the storage operations, as follows: NIM3 = Network Interface Module (TCP/IP, UDP handling); FSX and FSB3 = File System Modules (NFS and CIFS protocol handling, plus cluster interconnect on FSB3); and SIM3=Storage Interface Module (Disk controller / FC interface)
Titan 3110 has 31 gigabytes (GB) of memory, cache and NVRAM distributed within the Titan modules as follows:
- NIM3 - 3.5 GB memory per Titan
- FSX - 2.0 GB memory per Titan
- FSB3 - 14.5 GB memory per Titan, of which 2.0 is NVRAM and 8.0 is FS metadata cache. The remaining amount is used for buffering data moving to/from the disk drives and/or network.
- SIM3 - 11 GB memory per Titan, of which 8.0 is "sector" cache used for interface with RAID controllers and disk subsystem. This is the "other cache size" in the Titan as noted above.
For "stable storage" requirement, the Titan server writes first to battery backed (72 hours) NVRAM internal to the Titan. Data from NVRAM is then written to the the drive arrays as convenient, but always within a few seconds of arrival in NVRAM.
Server tuning:
- Disable file read-ahead, "read ahead -- disable"
- Disable shortname generation for CIFS clients "shortname -g off"
- Server running in "Native Unix" security mode, "security-mode set unix".
- Set metadata cache bias to small files: "cache-bias --small-files"
- Accessed time management was turned off: "fs-accessed-time set off"
- Jumbo frames were enabled.
Two 10GbE Ethernet ports were present on each cluster node, but only one was used per node.
