Seagate has upgraded its Exos Application Platform storage arrays with a new ASIC RAID controller that doubles performance and adds what Seagate calls self-healing to preserve data on defective hard disks.
The Exos X models are a rebranding of the old Exos AP line. The chassis can hold a mix of traditional hard disks as well as SSDs. It comes with software that automatically moves “hot” data, which is being frequently accessed, to SSDs, while less used, “cold” data is moved to the hard drives.
There are three Exos X products, defined by their size and drive-bay count. The 2U12 is a 2U chassis with 12 3.5-inch hard-drive bays; the 2U24 with is a 2U chassis has 24 drive slots; and the 5U84 with 84 slots in a 5U chassis. It has all of the standard connections: SAS, network attached SAS, Fibre Channel up to 32G, iSCSI up to 25G and a 10GBASE-T option as well.
