Additional information on the entire range of FAStT storage solutions can be found at: http://www.storage.ibm.com/hardsoft/disk/fastt/index.html Enterprise Storage Server (ESS) ESS provides integrated caching and RAID support for the attached disk devices. ESS can be configured in a variety of ways to provide scalability in capacity and performance. One ESS can support in excess of 28 TB and can utilize 2 Gbps Fibre Channel connectivity. Redundancy within ESS provides continuous availability. It is packaged in one or more enclosures, each with dual line cords and redundant power. The redundant power system allows ESS to continue normal operation when one of the line cords is deactivated. ESS provides an image of a set of logical disk devices to attached servers. The logical devices are configured to emulate disk device types that are compatible with the attached servers. The logical devices access a logical volume that is implemented using multiple disk drives. This allows ESS to connect to all IBM servers, from zSeries to iSeries, pSeries and xSeries, directly or through a SAN, thus helping the x455 fit into a heterogeneous environment containing a variety of server architectures. ESS offers several choices of host I/O interface attachment methods, including SCSI and Fibre Channel for xSeries.

Considerations when selecting a backup solution should include: Currently implemented backup solutions If you are consolidating a number of servers onto a single x445 solution, for example, you may want to take the opportunity to move from differing and distributed tape technologies (such as DDS and DLT) and consolidate those into a single, high-performance, automated solution. An example is the IBM Ultrium Autoloader. Current and projected capacity requirements Select a solution that has the ability to scale as capacity requirements increase. 84 IBM xSeries 455 Planning and Installation Guide Eserver

Enterprise Storage Server (ESS)

ESS provides integrated caching and RAID support for the attached disk devices.

ESS can be configured in a variety of ways to provide scalability in capacity and

performance. One ESS can support in excess of 28 TB and can utilize 2 Gbps

Fibre Channel connectivity.

Redundancy within ESS provides continuous availability. It is packaged in one or

more enclosures, each with dual line cords and redundant power. The redundant

power system allows ESS to continue normal operation when one of the line

cords is deactivated.

ESS provides an image of a set of logical disk devices to attached servers. The

logical devices are configured to emulate disk device types that are compatible

with the attached servers. The logical devices access a logical volume that is

implemented using multiple disk drives. This allows ESS to connect to all IBM

servers, from zSeries to iSeries, pSeries and xSeries, directly or through a SAN,

thus helping the x455 fit into a heterogeneous environment containing a variety

of server architectures. ESS offers several choices of host I/O interface

attachment methods, including SCSI and Fibre Channel for xSeries.

3.3.2

Tape backup

As with your disk subsystem, you need to carefully analyze backup requirements

before a tape solution is selected. Considerations when selecting a backup

solution should include:

Currently implemented backup solutions

If you are consolidating a number of servers onto a single x445 solution, for

example, you may want to take the opportunity to move from differing and

distributed tape technologies (such as DDS and DLT) and consolidate those

into a single, high-performance, automated solution. An example is the IBM

Ultrium Autoloader.

Current and projected capacity requirements

Select a solution that has the ability to scale as capacity requirements

increase.
