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 x450 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. For more information on the ESS, go to: http://www.storage.ibm.com/hardsoft/products/ess/index.html 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 x440 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. Performance requirements You need to consider the backup window available, as well as the amount of data being backed up when determining what your backup performance requirements will be. It is also important to consider the need for quick access to data committed to tape when selecting a solution. Connection requirements Will the tape solution be connected to an existing SAN fabric and if so, will this require additional fabric hardware? Hardware and software compatibility If you implement a new tape solution, you need to ensure that current backup and management software is still suitable. IBM Tivoli Storage Manager has plans to release 64-bit versions of their Linux and Windows clients, as do other software vendors. Disaster recovery procedures may also need to be revised. Chapter 3.

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 x440 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.
±
Performance requirements
You need to consider the backup window available, as well as the amount of
data being backed up when determining what your backup performance
requirements will be. It is also important to consider the need for quick access
to data committed to tape when selecting a solution.
±
Connection requirements
Will the tape solution be connected to an existing SAN fabric and if so, will this
require additional fabric hardware?
±
Hardware and software compatibility
If you implement a new tape solution, you need to ensure that current backup
and management software is still suitable. IBM Tivoli Storage Manager has
plans to release 64-bit versions of their Linux and Windows clients, as do
other software vendors.
Disaster recovery procedures may also need to be revised.
