Other Notes

The tested system was a BlueArc Titan 2200 2-node cluster with an HDS Universal Storage Platform (USP) 1100 storage array.
Titan 2200 servers were directly connected with dual 10Gb Ethernet cluster links
Titan servers had high memory option installed and all standard protection services enabled, including RAID, NVRAM logging, and media error scrubbing.
Titan uses Field Programmable Gate Arrays (FPGAs) to accelerate processing of network traffic and file system I/O. 14 (7 per Titan) FPGAs are used for NFS processing out of a total of 24 (12 per Titan) FPGAs in the system.
The USP 1100 was configured with 4 pairs of Front End Directors (FED), 384 15k RPM FC disks and 80 GB cache.
- Disk and FS configuration was 96 "2+2" RAID 10 LUs, 16 Titan storage pools (striped across 6 LUs each), 1 FS per storage pool. One hot spare disk was present.
- Four ports per FED were used. Each LU was exported via two ports for redundancy.
- The USP 1100 was connected to the Titan servers using redundant Brocade 4100 FC switches
For Uniform Access Rule compliance all LG's accessed all cluster namespace objects uniformly across all interfaces as follows:
- There are 2 network nodes: T0, T1 (Titan 0 and Titan 1)
- There are 16 physical target file systems (/r/v0�./r/v15) presented as a single cluster name space (NS1) with virtual root �/r� accessible to all clients.
- Each target file system belongs to one of the 2 network nodes. Each target file system is physically located on a separate storage pool consisting of six 2x2 RAID 10 LUNs per pool. Filesystems: N0: /r/v0, /r/v1, /r/v2, /r/v3, /r/v8, /r/v9, /r/v10, /r/v11; N1: /r/v4, /r/v5, /r/v6, /r/v7, /r/v12, /r/v13, /r/v14, /r/v15
- Each Node has two Virtual Servers, each with a separate own IP address. 2 Nodes X 2 Virtual Servers each = 4 possible paths for each client to each file system target. Virtual Servers: N0: VS1, VS3; N1: VS2, VS4
- 4 Virtual Servers X 16 File systems = 64 total data paths. Each LG ran 32 processes and addressed 8 of the 16 file systems across 4 Virtual Servers, or 32 total data paths, uniformly distributed across both Nodes. LGs picked alternating target file systems so that every 2 LGs addressed all 64 data paths.
- Each Load Generator (LG1�LG28) selects a file system target and rotates through the 4 paths to that file system target, then rotates to the next file system target and repeats the path rotation. 50% of the data paths accessed by each client were local to the Titan owning the IP address used to connect and 50% were accessed across the inter-cluster link using Cluster Name Space to insure a uniform spread of workload across all clients and all data paths.
- LG1: T0, VS1, /r/v0; T1, VS2, /r/v0; T0, VS3, /r/v0; T1, VS4, /r/v0; T0, VS1, /r/v1; T1, VS2, /r/v1; T0, VS3, /r/v1; T1, VS4, /r/v1; and so forth.
Each Titan contains four modules that perform all the storage operations, as follows: NIM = Network Interface Module (TCP/IP, UDP handling); FSA and FSB = File System Modules (NFS and CIFS protocol handling); and SIM=Storage Interface Module (FC interface and Cluster Interconnect)
Each Titan 2200 has 33.8 gigabytes (GB) of memory, cache and NVRAM distributed within the Titan modules as follows:
- NIM - 2.8 GB memory per Titan
- FSA - 4.0 GB memory per Titan
- FSB - 17.25 GB memory per Titan, of which 2.0 is NVRAM and 14.5 is FS metadata cache. The remaining amount is used for buffering data moving to/from the disk drives and/or network.
- SIM - 9.75 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, Titan writes first to NVRAM internal to the Titan. Data from NVRAM is then written to the USP 1100 cache, which is mirrored and battery backed for up to 48 hours, and from the USP 1100 cache data is written to disk. In the event of power failure the USP will flush all data in cache to disk before battery is exhausted.
Server tuning:
- Disable file read-ahead "fsm read-ahead 0 0"
- Disable shortname generation for CIFS clients "shortname -g off"
- Server running in "Native Unix" security mode.
- Set metadata cache bias to small files: "fsm cache-bias --small-files"
- Accessed time management was turned off: "fs-accessed-time set off"
- Jumbo frames were not enabled.
