SGI NAS Webページには ZFS採用は明記されてませんが、Datasheetから

Additional features include:
*)ZFS technology - the most scalable and flexible 128-bit file system
*)Unlimited snapshots and copy-on-write clones.
*)Support for NAS (NFS, CIFS, WebDAV, FTP) and support for SAN (iSCSI & FC)
*)Inline dedupe and compression reduce primary storage
*)Specialized devices, such as SSDs, accelerate read and write performance
*)Synchronous / asynchronous replication for easy disaster recovery
*)Set up remote back-ups and disaster recovery at off site locations
*)Manage disks and JBODs using command line or SGI NAS Management Viewer

Hybrid Storage Pools
"The Hybrid Storage Pool uses RAM, Solid State Devices (SSDs), and rotational
 drives all at once. As such, instead of just adding spindles, the design of
 the pool provides more degrees of freedom. Within the HSP, three different
 device types can be created: one virtual device type for cache
 (read operations); a log device (write operations); and a regular virtual
 device (capacity)."

SGI NAS Namespace Cluster Plug-in
"As the number of users and applications simultaneously accessing data
 constantly increase, any given storage server potentially can become
 a bottleneck, in terms of available I/O bandwidth, CPU, memory, network,
 and disk I/O resources."
