Tiered Storage with SAS/SATA Drives and Solid State Disks
Tiered storage makes a mix of high-performance SAS (serial-attached SCSI), SSD (Solid State Disk), and low-cost SATA drives much more efficient. By automating the migration of data from one type of media to another based on activity, the most active data tends to stay in the fastest media, improving overall throughput substantially. With the FXT NAS Caching Appliance, tiering is fully automated and transparent to servers and storage, out in front of disparate NFS NAS appliances. With the NST, Read and write cache is enabled with high speed media, dramatically improving overall performance. Write cache is performed in non-volatile media with redundant controllers, to insure date integrity and availability at all times.
