N-port ID virtualization (NPIV)
This is not currently supported.
Microsoft cluster
• Supported only by VMware with the ESX V3.5 update 1 or higher, but not supported with
VMware DRS and HA.
• Follow VMware instructions on how to install a Microsoft cluster on VMware virtual machines.
See http://www.vmware.com/pdf/vsphere4/r40/vsp_40_mscs.pdf.
• The quorum disk must be created from a raw device based on a dedicated SVSP virtual disk
assigned to all ESX servers that will serve Microsoft cluster virtual machines (nodes).
• SVSP thin provisioned virtual disks cannot serve as the quorum disk.
Installing and booting an VMware ESX server from the SAN
The following procedure, which must be done in order, allows you to configure a VMware ESX
server to boot from a LUN on the SAN.
1. From the VSM GUI:
a. Verify that you can see the LUN presented by the storage array as back-end LUs.
b. Follow the HP StorageWorks SAN Virtualization Services Platform Manager User Guide
procedures to create a storage pool.
c. Follow the HP StorageWorks SAN Virtualization Services Platform Manager User Guide
procedures to create a virtual disk from the storage pool.
d. Follow the HP StorageWorks SAN Virtualization Services Platform Manager User Guide
procedures to configure a UDH for the VMware server (choose VMware for the OS type,
and the LSI personality for the SCSI personality type).
e. Assign the SVSP virtual disk only to the ESX server that will use the virtual disk as its boot
device.
2. Follow VMware instructions on how to configure the HBAs. See Chapter 5 in http://
www.vmware.com/pdf/vsphere4/r40/vsp_40_san_cfg.pdf. Make sure to apply these
instructions to all HBAs and HBA ports for HA.
3. Insert the ESX install CD into the server and reboot the server.
4. While the server is rebooting, at the BIOS level, verify the SVSP virtual disk was recognized
by the HBA BIOS.
5. In the ESX install wizard, verify that the installation will be done to the VSM virtual disk. You
are able to recognize the SVSP virtual disks because they have LSI in their names.

VMware and large I/Os
When setting up a VMware server, change the default Disk.DiskMaxIOSize to 1 MB or less.
This can be done using the following steps:
