Product Name FXT 2500 (1 Node) Hardware Available October 2009 Software Available October 2009 Date Tested September 2009 SFS License Number 9020 Licensee Locations Pittsburgh, PA USA The Avere Systems FXT 2500 appliance provides tiered NAS storage that allows performance to scale independently of capacity. The FXT 2500 is built on a 64-bit architecture that is managed by Avere OS software. FXT clusters scale to as many as 25 nodes and support millions of IO operations per second and deliver multiple GB/s of bandwidth. The Avere OS software dynamically organizes data into tiers. Active data is placed on the FXT appliances while inactive data is placed on slower mass storage servers. The system accelerates performance of read, write and metadata operations. The FXT 2500 supports both NFSv3 and CIFS protocols. The tested configuration consisted of (1) FXT 2500 cluster node. The system also included a Linux server that acted as the mass storage system.

Server Tuning Notes ------------------- 3+1 RAID5 array was created on the Linux mass storage server using the following LSI MegaCli command line 'MegaCli64 -CfgLdAdd -r5 '[72:0,72:1,72:2,72:3]' WB ADRA Cached NoCachedBadBBU -strpsz32 -a0' and disk caches were disabled as follows 'MegaCli64 -LDSetProp -DisDskCache -L0 -a0'. This MegaCli command line creates a RAID5 3+1 array with write-back caching enabled in the controller (WB), adaptive read-ahead (ADRA), controller caching (Cached), caching disabled if the battery-backup unit fails (NoCachedBadBBU), a 32KB stripe unit size on controller zero (-a0). Complete documentation for the MegaCli command line tool is available at http://www.lsi.com/DistributionSystem/AssetDocument/ 80-00156-01_RevH_SAS_SW_UG.pdf.

Network Configuration Notes --------------------------- The FXT 2500 was attached via a single 10 GbE port to an Arista DCS-7124S 24 port 10 GbE switch. The load generating clients were attached to an HP ProCurve 2900-48G switch via a single 1 GbE link. The HP switch had a 10 GbE uplink to the Arista switch. The mass storage server was attached to the HP switch via a single 1 GbE link. A 1500 byte MTU was used throughout the network. Benchmark Network ================= An MTU size of 1500 was set for all connections to the switch. Each load generator was connected to the network via a single 1 GbE port. The SUT was configured with a single IP address.

A separate, battery-backed NVRAM module is used to provide stable storage for writes that have not yet been written to disk. Stable Storage ============== The Avere filesystem logs writes and metadata updates to the NVRAM module. Filesystem modifying NFS operations are not acknowledged until the data has been safely stored in NVRAM. The battery backing the NVRAM ensures that any uncommitted transactions persist for at least 72 hours. System Under Test Configuration Notes ===================================== The system under test consisted of (1) Avere FXT 2500 node. The node was attached to the network via 10 Gigabit Ethernet. An FXT 2500 node contains (8) 450 GB SAS disks. The Linux mass storage system was attached to the network via a single 1 Gigabit Ethernet link. The mass storage server was a 4U Supermicro server configured with an (4) 1TB disk SATA RAID5 array.
