The Sun StorEdge 9980 system provides extreme levels of performance and capacity needed in large data center environments. This highly available and massively scalable storage system has a base configuration consisting of two frames: the Control Frame and the Array Frame. The Control Frame contains the cache and switch modules, host and drive interfaces, disk array processors, and the service processor. The system's virtualization capabilities enable storage consolidation, which helps to reduce total cost of ownership (TCO) by enabling connections to multiple hosts and allows for more flexibility in configuring a storage area network (SAN) infrastructure. The storage system is easy to operate and control and helps to simplify data management. Software is available to support key storage applications typically used in data center environments including path management, real-time replication, and remote mirroring for disaster recovery.SE9980 Disk controller frame includes disk controller which supports RAID 5/RAID 1, Product Documentation, Microcode Kit and HiTrack. Consists of two storage clusters (controller logic) without cache memory module and shared memory module. Includes one ACP pair.
