ETERNUS DX80, 900GB (2x 450GB) 15000rpm SAS HDD, 1.2GHz CPU, 1GB Cache, Gigabit Ethernet
The Data Safe
With three different base models, ETERNUS DX80 entry level disk storage systems can either connect to hosts via Fibre Channel (with 8 Gbit/s performance option for DX80) , iSCSI or SAS. They are easy to install, configure, operate and maintain, integrating well with host operating systems, servers, network infrastructures and backup solutions.
Different drive types can be mixed and matched, secured by the relevant monitored RAID levels (0, 1, 5, 1+0, 5+0 and 6) and features to ensure data integrity. Administrators can dynamically move data, spin disks down to save energy or encrypt disks to prevent unauthorized access.
In the event of power outages, the content of the cache is secured to flash memory. A backup copy is always at hand via snapshots and clones.
The energy saving storage device can be scaled from 600 GB to 120 TB and is equipped with all state-of-the-art capacities of high-performance SAS and large capacity Nearline SAS disk drives as well as Solid State Drives.
The standard system is delivered with 8 snapshots and can be extended to 1,024 snapshots. The ETERNUS DX80 is equiped with either four 4 or 8 Gbit/s Fibre Channel, 1 Gbit/s iSCSI or 3 Gbit/s SAS host ports on two controllers with overall 4 GB cache. The Fibre Channel or iSCSI model can connect up to 128 servers in SAN mode.
