900GB SAS 10K RPM Disk Drives 172 65.6 TB
73GB SAS-2 SSD Write Flash Accelerator Used for the ZFS Intent Log (ZIL). 8 584.0 GB
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 184 67.1 TB
Number of Filesystems 176
Total Exported Capacity 62.96 TB
Filesystem Type ZFS
Filesystem Creation Options default
Filesystem Config 176 ZFS file systems
Fileset Size 24611.6 GB

Both controllers are setup with 8 pools total (4 pools per controller). Each of the controller's pools are configured with 20 disk drives, 1 write flash accelerator and 1 spare disk drive. The pools are also set up to mirror the data (RAID1) across all 20 drives. The write flash accelerator in each pool is used for the ZFS Intent Log (ZIL). All pools are configured with 22 ZFS file systems each. Since each controller is configured with 4 pools and each pool contains 22 ZFS file system, in total each controller has 88 ZFS file systems. Both of the controllers together in total have 176 ZFS file systems. 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.

1 4 CPU 2.1GHz Intel Xeon E5-2658 NFS, ZFS, TCP/IP, RAID/Storage Drivers

Processing Element Notes

Each Oracle ZFS Storage ZS3-2 controller contains 2 physical processors, each with 8 processing cores.

Memory Notes

The Oracle ZFS Storage ZS3-2 controllers' main memory is used for the Adaptive Replacement Cache (ARC) the data cache and operating system memory.

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 Oracle ZFS Storage ZS3-2 cluster set up in an active-active configuration.
