Machine Description 9406 models
2105 2105 Enterprise Storage Server
The 2105 is the enclosure of the IBM TotalStorage Enterprise Storage Server (ESS). Each 2105
incorporates dual RISC 4-way SMP processors, read/write cache up to 64 GB, up to 384 MB
non-volatile storage (NVS) (write cache), four device adapter pairs, and 8-packs of disks in the optimum
serial loop configuration.
The ESS offers excellent scalability. The Model 800 supports up to 55.9 TB of physical capacity that can
be configured as RAID 5, RAID 10, or a combination of both. The E10, E20, F10, and F20 ESS models
range from 420 GB to over 1.6 TB (E10), 11.2 TB (E20), 3.3 TB (F10), and 22.4 TB (F20) of RAID-5
effective capacity.
Enterprise Storage Server supports platforms including RS/6000 and pSeries® running AIX and many
leading UNIX® variants, Netfinity, xSeries, other PC servers running Windows NT or Novell NetWare,
and Compaq AlphaServers running OpenVMS. In addition, the ESS supports IBM S/390® and IBM
eServer zSeries® servers with selected host operating systems.
Storage capacity is partitioned among the attached servers using the Web-based StorWatch ESS
Specialist management tool.
