When allocating LUNs or RAID groups for ESXi systems, remember that multiple operating systems
use and share that resource. The LUN performance required by the ESXi host might be much higher
than when you use regular physical machines. For example, if you expect to run four I/O intensive
applications, allocate four times the performance capacity for the ESXi LUNs.

When you use multiple ESXi systems in with vCenter Server, the performance requirements for the
storage subsystem increase correspondingly.

The number of outstanding I/Os needed by applications running on the ESXi system must match the
number of I/Os the HBA and storage array can handle.
