One processor is additionally provided for each X2000 I/O Carrier
System as the I/O processor (two I/O processors on model
SX130-60C).
* Notice:
SX100 with external devices and/or VM2000
If many external devices are connected to the SX100, X2000 requires
more memory. When FibreChannel disk peripherals are connected, for
example, 1024 MB should be selected for BS2000 and 1024 MB for
X2000 on SX100-B. This generally leads to no noticeable restriction
on the main memory available for BS2000, since in these cases the
memory area for DAB can be dispensed with.
If several guest systems are used under VM2000 (up to 4 guest sys-
tems are possible) more memory is required. To this the main memory
of SX100–B is expandable to 4 GB. SX100-C servers have a minimum
memory size of 4 GB.
The maximum main memory that can be installed for a BS2000 instance
is 12 GB on an SX130 and on an SX 140 series server and 32 GB on an
SX150 series server.
It is not necessary to change the main memory standard settings in
most cases. An expansion of main memory should be considered in
following cases:
1)Expansion of the BS2000 main memory
If more than the recommended max. number of virtual machines are
supposed to run, the main memory for BS2000 should be expanded.
(Max. 15 virtual machines are allowed.)
As well an expansion of main memory can become necessary running
extremely many or out of scale tasks.
2)Expansion of the X2000 main memory
In case of an expansion of the total main memory (e.g. for BS2000)
a part for X2000 should also be arranged. A X2000-part of about 20%
of the additional memory is said to be a recommended value.
In case of large configurations (from about 512 LUNs and 32 Cen-
tricStor devices) more memory for X2000 has to be provided than is
foreseen in the standard models.
