48 Configuring Storage
• Up to 16 SAN-Configured Servers, Single-Path Data, Single Controller
(Simplex)
— This configuration contains up to 16 XenServer hosts, each
with one or two NICs that are bonded to provide high availability for
iSCSI connectivity and an PowerVault MD3000i storage array enclosure
with one RAID controller. One or two of each host's NICs are connected to
an Ethernet switch, and the Ethernet switch has a connection to the I/O
port on the PowerVault MD3000i RAID controller. Two optional
PowerVault MD1000 storage enclosures can be daisy-chained to the
PowerVault MD3000i storage array to provide additional storage capacity.
As shown in Figure 5-15, XenServer hosts connected to same controller I/O
port can be part of a single pool. Two NICs on the XenServer host can be
bonded to provide high availability for the iSCSI storage traffic. For more
details on how to configure high availability for IP storage, see "High
Availability Configuration and IP Storage Traffic Segregation" on page 67.
