Product Name COUGAR 6720 Hardware Available August 2008 Software Available December 2010 Date Tested March 2011 SFS License Number 3634 Licensee Locations Milpitas, CA The Cougar 6000 represents LSI ONStor's family of scalable clustered NAS gateway systems targeted at high-end enterprise file serving environments. Cougar 6000 systems are available in two models: Cougar 6720 & Cougar 6520. These systems are based on 64-bit, multi-core network processors which feature system-on-a-chip design, with integrated i/o and hyper-transport interconnects for high data throughput at significantly lower power consumption. Each Cougar 6000 system supports up to eight 4Gb Fibre Channel and eight Gigabit Ethernet ports in a highly available configuration within a compact 2U form factor. Cougar 6000 systems are architected to scale out to multiple NAS gateways in a single cluster and deliver high performance and capacity scaling across a broad range of storage systems.

Included in each was a 7900 controller module and 10 shelves of 16 Fibre Channel drives (15K RPM). Each array had 8 filesystems, each striped over its own set of 20 disks. Four file systems were assigned to controller A and four were assigned to controller B. While both Cougar blades could access either controller of either storage system for failover purposes, each blade was assigned to its own 7900 during the SPEC test. Storage settings included read ahead off, read cache enabled, write cache enabled, and 128 KB stripe size, Network Configuration ===================== Item Number of No Network Type Ports Used Notes ----- ------------ ----------- ----- 1 Gigabit 8 Four GbE ports per Cougar 6720 blade. The 4 Ethernet ports were aggregated into 1 logical port. Network Configuration Notes --------------------------- A Cisco Catalyst 2960G ethernet switch (48 ports) was utilized. The network interfaces used standard frames. Benchmark Network ================= The Cougar 6720 was connected to the Cisco switch via GbE connections (8 ports). The connections were organized into 2 groups of 4. Each group of 4 was aggregated at the switch and the Cougar blade. Each client was connected to the Cisco switch with a 1 GbE connection.

Each blade has 2 physical processors (Broadcom SiByte 1480 - four processing cores per chip) for data path processing (TCP/IP, NFS, CIFS, filesystem) and 1 physical processor (Broadcom SiByte 1125 - one processing core per chip) for operating system management and control, four Gigabit Ethernet ports and four 4Gb/s Fibre Channel ports.

Stable Storage ============== The NAS system under test includes the Cougar 6720 gateway and LSI 7900 storage. Only the LSI 7900 storage system has stable storage. The LSI 7900 stable storage consists of disk drives and DDR2 RAM with a backup system utilizing batteries and USB-based flash drives. In the event of power failure, the battery backed system writes cache data to flash drives. If the batteries are not charged, then the storage system operates in pass-through mode with the disk drives being considered the only stable storage. Data is stored in stable storage before NFS stable write and commit operations are acknowledged. Note that the USB flash drives are implicitly included in the NV RAM line in the Memory table. System Under Test Configuration Notes ===================================== The test configuration used dedicated resources (network switch, SAN switch, storage). Other System Notes ================== Standard LSI storage default settings were utilized.

The LSI ONStor Cougar 6720 Gateway had two blades, each running 1 virtual server and 8 file systems. Each blade was configured with 1 logical interface to the clients (an aggregation of four GbE interfaces). To satisfy the uniform access rule, each client used 32 mount points, 2 for each of the 16 file systems in the Cougar 6720 Gateway. Thus each client's load was evenly distributed over the 16 file systems and the 2 network interfaces. On the storage side, each virtual server could access any of the raid groups via either of the 2 storage systems.
