Disks and Filesystems

Description Number of Disks Usable Size
300GB SAS 15K RPM Disk Drives 280 37.1 TB
500GB SATA 7.2K RPM Disk Drives Each controller contains 2 of these disk drives and are mirrored and are not used for cache data or data storage. 4 899.0 GB
Total 284 37.9 TB
Number of Filesystems 32
Total Exported Capacity 36.32 TB
Filesystem Type ZFS
Filesystem Creation Options default
Filesystem Config 32 ZFS file systems
Fileset Size 31008.5 GB

The storage configuration consists of 12 shelves, 10 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 140 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 34 disk drives, 1 write flash accelerator, 1 read flash accelerator and 1 spare disk drive. The pools are then set up to mirror the data (RAID1) across all 34 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 file systems each. Since each controller is configured with 4 pools and each pool contains 4 ZFS file system, in total each of 2 controllers has 16 ZFS file systems. The SUT has 32 ZFS file systems for the benchmark. There are 2 internal mirrored system disk drives per controller and are used only for the controllers core operating system. These drives are not used for data cache or storing user data.

Network Configuration

Item No Network Type Number of Ports Used Notes
1 10 Gigabit Ethernet 4 Each controller has 2 Dual port 10 Gigabit Ethernet cards using only a single port on each and using Jumbo Frames

Network Configuration Notes

There are 8 ports total but 4 are active at a time for high availibility. The MTU size is set to 9000 on each of the 10 Gigabit ports.

Benchmark Network

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

Memory Notes

The Sun ZFS Storage 7420 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).

Stable Storage

The Stable Storage requirement is guaranteed by the ZFS Intent Log (ZIL) which logs writes and other file system changing transactions to either a write flash accelerator or a disk drive. Writes and other file system 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 4 backend SAS channels from both controllers, the remaining active controller can complete any outstanding transactions using the ZIL. In the event of power loss to both controllers, the ZIL is used after power is restored to reinstate any writes and other file system changes.

System Under Test Configuration Notes

The system under test is a Sun ZFS Storage 7420 cluster set up in an active-active configuration.

Load Generator Configuration Notes

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

Uniform Access Rule Compliance

Every client used 256 processes. All 32 file systems are mounted and accessed by each client and evenly divided amongst all network paths to the 7420 controllers. The file systems data was evenly distributed on the backend.
