SGI NAS is a unified storage management platform that delivers enterprise-class features and runs on industry standard hardware. SGI NAS helps organizations implement high performance, yet cost-effective data storage solutions by taking advantage of features such as inline deduplication, unlimited snapshots and cloning, hardware-agnostic solutions, and high availability support. All enterprise features, such as thin provisioning, storage snapshots, cloning, and replication, are built in and implemented without any additional license or costs. In contrast, with a traditional appliance model, it is required to do a controller upgrade if performance, or the number of spindles, reach a certain level.

|
Filesystem Creation Options
|
Select "Performance Optimized" in the administative GUI to create one mirrored zpool with 32 vdevs of 2 disks each, 4xL2ARC, and 2xSLOG. Then create 4 folders with atime=off and NFS export the folders.
|
|
Filesystem Config
|
ZFS stripes the storage pool across all the vdevs/mirror sets. The exported folders share all the space in the storage pool.
|
|
Fileset Size
|
5760.9 GB
|
Factory preset configuration "Performance Optimized". The storage configuration includes 64 disk drives, 2 write flash devices, and 4 read flash accelerators. A single pool is created by mirroring pairs of disks, then striping across all the mirror sets. The write flash accelerator is used for the ZFS Intent Log (ZIL) and the read flash accelerator is used as a Level 2 Adaptive Replacement Cache (L2ARC) for the pool. The pool is configured with 4 file systems.
