The Cougar 6000 represents 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.

A standard Fujitsu ETERNUS4000 model 500 storage system was utilized. Sixteen shelves of 15 Fibre Channel drives (15K RPM) each were available. Of the 240 drives, 224 were used for the file system and 4 were used for Fujitsu code and logging. In addition, Cougar maintenance and core dump files resided on the 2 of the 4 disks. Each of the 32 file systems was striped over its own set of 7 disk drives. Sixteen file systems were assigned to Controller Module 0 and the other 16 to Controller Module 1. While both Cougar blades could access both Controller Modules for failover purposes, each blade was assigned to its own Controller Module during the SPEC test. The Cougar Gateway utilized the Fujitsu storage default settings including Read Cache, Write Cache, Write Cache Mirroring, and 64 KB stripe size.

Network Configuration Notes
A Dell PowerConnect 6248 ethernet switch (48 ports, 184 Gb backplane) was utilized. The network interfaces used standard frames.
Benchmark Network
The Cougar 6720 was connected to the Dell 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 of the 3 clients was connected to the Dell switch with a 1 GbE connection.

Processing Element Notes
Each Cougar 6720 contains two processing blades. 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.

Memory Notes
Each Cougar 6720 NAS blade has 8 GB of memory for the data path (protocol and file system operations) and 1 GB of memory for operating system management and control.
Stable Storage
Stable storage in the disk system consists of disk drives and DDR2 RAM with a backup system utilizing batteries and disk drives. In the event of power failure, the battery backed system writes cache data to system disk drives. Data is stored in stable storage before NFS stable write and commit operations are acknowledged.
System Under Test Configuration Notes
The test configuration used dedicated resources (network switch, SAN switch, storage).
Other System Notes
Standard Fujitsu storage default settings were utilized.

Uniform Access Rule Compliance
Thirty-two processes were utilized on each load generating client. The ONStor Cougar 6720 Gateway had two blades, each running 1 virtual server and 16 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, 1 for each of the 32 file systems in the Cougar 6720 Gateway. Thus each client's load was evenly distributed over the 32 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 controllers.
