• Dell systems shipped with Core i3 series processors support only
UDIMM memory.
• On Non-Uniform Memory Access (NUMA) enabled systems installed with
ESX, it is recommended that you populate all processor nodes with similar
memory modules to enable balanced distribution of memory across nodes.
You may face performance degradation issues or ESX may fail to boot with
unbalanced memory distribution across nodes.
The following error message may be displayed:
The BIOS reports that NUMA node X has no memory.
This problem is either caused by a bad BIOS or a
very unbalanced distribution of memory modules.
NOTE:
For more information about NUMA, see VMware knowledge base
articles: kb.vmware.com/kb/1003690 and kb.vmware.com/kb/1570. Also see,
VMware's Resource Management Guide for ESX 4 at

• Storage Logical Unit Numbers (LUNs) (on local system) are supported
only with PERC-based RAID configurations.
• Dell PowerVault NX1950 is supported only as an iSCSI storage device. It is
not supported as a network attached storage (NAS) device.
• PowerVault MD1000 and PowerVault MD1120 storage arrays provide
external storage to a single ESX host or to a maximum of two hosts in a
split configuration.
• PowerVault MD1000 and PowerVault MD1120 storage arrays do not
support features that require shared storage among ESX hosts, such as
VMotion, HA, and DRS.
• PowerVault MD3000 supports HA and VMotion.
• ESX supports a maximum virtual disk size of 2 TB. Simple RAID groups
(0, 1, 5, and 6) can be split into multiple virtual disks.
