Performance
The IXS, IXA, and iSCSI attached servers have their own memory
and one or more processors, but share the iSeries™ hard disk drive storage through virtual
(simulated) disk drives. The disk drives are allocated to Windows by creating
a storage space object on the iSeries. The major difference between the integrated
servers and stand-alone servers is that stand-alone servers tend to use dedicated
disk drives and the integrated servers use iSeries storage spaces as virtual disks. iSeries integrated servers also include optional features such as Windows drivers
to share iSeries tape drives, CD and DVD drives, along with high speed virtual
Ethernet adaptors.
The use of iSeries storage spaces (virtual drives) provides
performance benefits that are not typically available in stand-alone environments
without significant storage fabric investment and maintenance costs. However,
it also imposes some limitations. You should consider these limitations when
planning and configuring integrated servers. The information below highlights
some considerations affecting performance.
