IBM software
If you are running IBM software such as WebSphere®, Lotus®, and Tivoli®
products on VMware ESX Server, you must have an IBM Remote Technical
Support ServicePac® or IBM VMware Support Line agreement through the
IBM Support Line or the IBM equivalent. You must have a current Software
Maintenance Agreement to receive support for the IBM software products in
this environment. Individual IBM software products can have a level of
customer support beyond that described in the product announcement. If
applicable, information about the added support will be included in the
specific product announcement letter.
VMware ESX software is designed to be transparent to the middleware and
applications that operate above the VMware guest operating system. If an
IBM software problem occurs only within a VMware ESX environment, it will
be considered a transparency problem and will be directed to VMware for
resolution. The IBM VMware Support Line is available to provide assistance
in working with the customer and the VMware Business Partner to resolve this
type of problem.
Customer implementations that are not covered by an IBM VMware Support
Line agreement are required to re-create the problem in a native environment
without VMware in order to use Software Maintenance support services for
the IBM software that is experiencing the problem.
1.6 IBM fourth generation XA-64e chipset
The x3850 M2 and x3950 M2 use the fourth generation of the IBM XA-64e or
eX4 chipset.
This chipset is designed for the Xeon MP processor family from Intel. The IBM
eX4 chipset provides enhanced functionality and capability with significant
improvements in scalability, decreased memory latency, increased memory
bandwidth and increased I/O bandwidth. The architecture consists of the
following components:
One to four Xeon dual-core, quad-core, or 6-core processors
Hurricane 4 Memory and I/O Controller (MIOC)
Eight high-speed memory buffers
Two PCI Express bridges
One Enterprise Southbridge Interface
Figure 1-12 on page 28 shows a block diagram of the x3850 M2 and x3950 M2.
