HP 3PAR Citrix Implementation Guide

In the example above, there are five paths to the HP 3PAR StoreServ Storage from each HBA port.
Restrictions on Volume Size and Number
Follow the guidelines for creating virtual volumes (VVs) and virtual LUNs (VLUNs) in the HP 3PAR
Command Line Interface Administrator’s Manual while adhering to these cautions and guidelines:
• This configuration supports sparse LUNs (meaning that LUNs may be skipped). LUNs may
also be exported in non-ascending order (e.g., 0, 5, 7, 3).
• The HP 3PAR StoreServ Storage supports the exportation of VLUNs with LUNs in the range
from 0 to 16383.
• Testing was limited to 256 LUNs per storage server port (target) using LUN numbers 0 to 255.
• The maximum LUN size that can be exported to a Citrix host is 16 TB.
• Citrix XenServer 6.x has a supported limit of 75 multipathed LUNs per host (used by storage
repositories).
