EMC has announced a 1PB+ version of Symmetrix, the largest drive array curently available. It can have up to 2,400 500GB low-cost Fibre Channel (LC-FC) drives. These are the same Seagate drives that HP calls FATA (Fibre Channel ATA Technology-Attached) arrays. EMC said it is the only supplier using this technology in high-end arrays, classing the HP EVA arrays as mid-tier devices.
EMC said Symmetrix DMX-3 arrays can now have three disk tiers as a foundation for information lifecycle management (ILM) within a single array: mission-critical high-speed Fibre Channel drives at 15,000 rpm and 146GB capacity; business critical mid-speed FC drives at 10,000rpm and 300GB capacity; and backup/archive 7,200 rpm 500GB LC-FC drives.
The company also announced a new low-end DMX-3 configuration with 7TB capacity and 96 drives. Customers can start with this and scale up to the largest model.
In a multi-product announcement EMC also introduced:-
- MPFSi (Multi-Path File System for iSCSI) which lowers the file system overhead in transferring large files from block-based file storage to servers across an IP network. It can realise up to a four-fold improvement over competing network-attached storage (NAS) boxes. A Linux server client is ready now. Other clients will be delivered later.
- Thin provisioning of Celerra NAS storage so that applications are only given the storage they physically need instead of the maximum they will eventually need. The technology automatically increases the allocated ammount if it fills up.
- Better heterogeneous IP storage management and operation through Rainfinity Global File Virtualisation. This operates within a global namespace and means files can be moved non-disruptively bewtween different suppliers' IP storage products.
- Synchronous replication for Celerra NAS storage to make data protection more robust and aid disaster recovery.
- New software technology for Celera NAS boxes so that e-mails and other files needed for a litigation case can be identified and retained.
EMC officers said that the new DMX-3 products were ready for 4Gbit/s Fibre Channel technology but didn't support it yet.
The company views IP storage as including both file (NAS) and block (IP SAN) disk storage in an IP network. Customers, the company believes, will want both file and block services within an IP storage network.
EMC also said that it would be logical to group together server virtualisation (VMware), block virtualisation (InVista) and file virtualisation (Rainfinity) in a single infrastructure or product.
