PowerVault MD3000i and MD32x0i Storage
Enclosures
The PowerVault MD3000i and MD32x0i storage enclosures are a high
performance iSCSI Storage Area Network (SAN) designed to deliver storage
consolidation and data management capabilities in an easy to use, cost effective
solution. PowerVault
MD3000i and MD32 x 0i support the following features:
• The Dell PowerVault MD3000i and MD32 x 0i storage enclosures consists
of a standard or high-availability configuration.
• The standard model has a single controller with two or four 1GbE ports. It
can be deployed to support up to 16 hosts non-redundantly.
• The high-availability model has dual controllers with two 1GbE ports per
controller for a total of eight 1GbE ports. The dual controller option can
connect up to 16 fully-redundant hosts.
• The entire PowerVault MD3000i and MD32
x 0i storage enclosures are
managed from a single, user-friendly software application known as MDSM.
MDSM streamlines the management and maintenance of storage as it
scales.
• In-band management of an PowerVault MD3000i and MD32
x 0i storage
enclosures from a XenServer host are not supported. To manage
PowerVault MD3000i and MD32
x 0i storage enclosures using MDSM,
install the MDSM software on a separate supported Micorsoft Windows or
Linux management station.
XenServer is pre-installed with the open-iSCSI initiator that can be used to
connect to
PowerVault MD3000i and MD32 x 0i storage enclosures . Alternatively,
a software iSCSI initiator inside a virtual machine (VM) can be used to add a
storage volume from
PowerVault MD3000i and MD32 x 0i storage enclosures .
