The NetApp(R) FAS3210 represents the entry of the line of the FAS3200 family of storage systems with NetApp's unified storage architecture. It features three models: the FAS3210, FAS3240 and FAS3270. The FAS3200 series performance is driven by a 64-bit architecture that uses high throughput, low latency links and PCI Express for all internal and external data transfers. With the FAS3200 series and Data ONTAP 8.0.1 you can efficiently consolidate SAN, NAS, primary, and secondary storage on a single platform. Data ONTAP 8.0.1 is designed to provide customers with the next generation of features and functionality to ensure they are able to meet the demands of growing workloads. NetApp has designed systems to make them easy for you to install, configure, manage, and upgrade so you can quickly adapt your storage infrastructure to meet your changing business needs. You can minimize the use of data center resources including power, cooling, and floor space-by taking advantage of a comprehensive set of storage-saving software features in Data ONTAP like Deduplication and Thin Provisioning (FlexVols).

Filesystem Creation Options	64-bit aggregate option was selected during creation of the aggregates that housed the SFS filesystems on each controller.
Filesystem Config	Each filesystem was striped across 68 disks
Fileset Size	7585.1 GB

The storage configuration consisted of 6 shelves, each wth 24 disks. The 6 shelves were on 2 SAS ports on each storage controller. Six shelves are in a single 'stack'. Two ports on each filer connect to top & bottom of the stack. (A 'stack' has 4 connections, 2 at top & 2 bottom). Each storage controller was the primary owner of 72 disks, with 68 disks in those shelves placed into a single 64-bit aggregate. Each aggregate was composed of 4 RAID-DP groups, each RAID-DP group was composed of 15 data disks and 2 parity disks. A seperate 3 disk RAID-DP set holds Data ONTAP. Each volume was striped across all disks in the aggregate where it resided. Each controller was the owner of a single volume, but the disks in each aggregate were dual-attached so that, in the event of a fault, they could be managed by the other controller via an alternate loop. A separate flexible volume residing in a three-disk root aggregate on each controller was created to hold the Data ONTAP operating system and system files. The remaining disks owned by each controller were reserved for spares.

Network Configuration Notes

There were two ports from the dual-port 1 gigabit ethernet network adapter configured on each storage controller. The active interfaces were configured to use jumbo frames (MTU size of 9000 bytes). All network interfaces were connected to a Cisco 6509 switch, which provided connectivity to the clients.

An MTU size of 9000 was set for all connections to the switch. Each load generator was connected to the network via a single 1 GigE port.

Memory Notes

Each storage controller has main memory that is used for the operating system and for caching filesystem data. A separate battery-backed NVMEM section of main memory is used to provide stable storage for writes that have not yet been written to disk.

The WAFL filesystem logs writes and other filesystem modifying transactions to the NVMEM. In an active-active configuration, as in the system under test, such transacations are also logged to the NVMEM on the partner storage controller so that, in the event of a storage controller failure, any transactions on the failed controller can be completed by the partner controller. Filesystem modifying NFS/CIFS operations are not acknowledged until after the storage system has confirmed that the related data are stored in NVMEM of both storage controllers (when both controllers are active). The battery-backed NVMEM ensures that any uncommitted transactions are preserved for at least 72 hours.

The system under test consisted of two FAS3210 storage controllers and 6 storage shelves, each with 24 1TB SATA disk drives. The two controllers were executing Data ONTAP 8.0.1 software operating in 7G mode. They were configured in an active-active cluster failover configuration, using the high-availability cluster software option in conjunction with iWarp over built-in 10GigE cluster interconnect. One dual-port 1 gigabit ethernet adapter was present on each storage controller. The storage shelves were connected to one of the SAS port pairs on one of the SAS adapters in one controller and the another port pair was connected to one of the SAS port pairs on the other controller. The system under test was connected to a 1 gigabit ethernet switch via 4 network ports.

All standard data protection features, including background RAID and media error scrubbing, software validated RAID checksumming, and double disk failure protection via double parity RAID (RAID-DP) were enabled during the test.

Load Generator Configuration Notes

All filesystems were mounted on all clients, which were connected to the same physical and logical network.

Each load-generating client hosted 28 processes. The assignment of processes to filesystems and network interfaces was done such that they were evenly divided across all filesystems and network paths to the storage controllers. The filesystem data was striped evenly across all disks and SAS adapters and on to the storage backend.
