Coraid ZX4000 Multi-Petabyte File Storage Appliance Now Available

Coraid has announced general availability of the ZX4000, latest in its ZX line of file storage appliances that leverage hybrid flash storage pools and a modular architecture in order to handle mixed workloads for enterprise and cloud applications. Used in tandem with Coraid’s EtherDrive block storage technology, the ZX4000 can help support shared, multitenant file and block storage pools at the multi-petabyte scale by adding additional SRX and ZX appliances.

Coraid’s ZX appliances leverage the Zettabyte File System (ZFS) and as well as RAIN and RAIDZ-3 options to protect against the failure of up to three shelves or drives with storage efficiency of approximately 80 percent. The ZX4000 is capable of simultaneously serving NFS and CIFS over multiple 1 GbE and 10 GbE links, with a Coraid Ethernet backbone that supports deploying new capacity anywhere on the network.
