Avere Systems released its first FXT Series storage appliances in November 2009. Each appliance contains a mix of storage media, to include: DRAM, NVRAM, SSD and SAS HDDs. These hybrid array appliances are used to form a storage cluster using a clustered file system. The FXT nodes act as write-back cache devices that sit in front of network-attached storage or object storage and are the mount point for computing clients sending file requests using NFS or CIFS/SMB protocols.
