The Sun ZFS Storage 7320 appliance offers enterprise NAS capabilities with industry-leading Oracle integration and storage efficiency in a small, affordable, high-availability configuration. Its simplified set up and management combine with industry-leading storage analytics to make it the ideal solution for departments, small enterprises, and application-specific deployments in large data centers. The Sun ZFS Storage 7320 is Oracle's mid-range NAS storage appliance - it serves as a balance point between the high performance Sun ZFS Storage 7420 and the Sun ZFS Storage 7120.

The storage configuration consists of 6 shelves, 4 with 24 disk drives, 2 with 20 disk drives and 4 write flash devices. Each controller head has 4 read flash accelerators. Each controller is configured to use 68 disk drives, 4 write flash accelerator devices and 4 read flash accelerator devices. The controller is then set up with pools by dividing the disk drives, write flash accelerators and read flash accelerators into 4 pools. Each of the controller's pools is configured with 17 disk drives, 1 write flash accelerator and 1 read flash accelerator. The pools are then set up to stripe the data (RAID0) across all 17 drives. The write flash accelerator in each pool is used for the ZFS Intent Log (ZIL) and the read flash accelerator is used as a level 2 cache (L2ARC) for the pool. All pools are configured with 4 ZFS filesystems each. Since each controller is configured with 4 pools and each pool contains 4 ZFS filesystem, in total each controller has 16 ZFS filesystems. The SUT has 32 ZFS filesystems for the benchmark.

Network Configuration Notes

None

Each controller was configured to use a single port of a dual port 10GbE network adapter for the benchmark network. All of the 10GbE network ports on both the load generators controllers were connected to the Arista 7124SX switch that provided connectivity.

Memory Notes

The Sun ZFS Storage 7320 appliance controllers' main memory is used for the Adaptive Replacement Cache (ARC) the data cache and operating system memory. A separate device, a write flash accelerator is used for the ZFS Intent Log (ZIL). The read flash accelerator is dedicated storage used also to hold cached data and is called the Level 2 Adaptive Replacement Cache (L2ARC).

The Stable Storage requirement is guaranteed by the ZFS Intent Log (ZIL) which logs writes and other filesystem changing transactions to either a write flash accelerator or a disk drive. Writes and other filesystem changing transactions are not acknowledged until the data is written to stable storage. Since this is an active-active cluster high availability system, in the event of a controller failing or power loss, the other active controller can take over for the failed controller. Since the write flash accelerators or disk drives are located in the disk shelves and can be accessed via the 2 backend SAS channels from both controllers, the remaining active controller can complete any outstanding transactions using the ZIL.

The system under test is a Sun ZFS Storage 7320 appliance cluster set up in an active-active configuration.

Load Generator Configuration Notes

Filesystems were mounted on all clients and all were connected to the same physical and logical network.

Every client used 112 processes. The assignment of client processes to filesystems and network interfaces was done so that they were evenly divided amongst all filesystems and network paths to the 7320 controllers. The filesystems data was evenly distributed on the backend.
