Figure 2-12. Cabling a Two-Node Cluster (Dual HBA, Redundant Data Paths From Each
Node)
For a more detailed discussion of redundancy and nonredundancy, as well as
alternate path software, see the PowerVault MD3000 Hardware Owner’s
Manual.
One of the features of the MD3000 is the ability to add up to two MD1000
expansion enclosures for additional capacity. This expansion increases the
maximum physical disk pool to 45 3.5" SAS and/or SATA II physical disks.
As described in the following sections, you can expand with either a brand
new MD1000 or an MD1000 that has been previously configured in a direct-
attach solution with a PERC 5/E system.
NOTICE:
Ensure that all MD1000 expansion enclosures being connected to the
MD3000 are updated to the latest Dell MD1000 EMM Firmware from
support.dell.com. Dell MD1000 EMM Firmware versions prior to A03 are not
supported in an MD3000 array; attaching an MD1000 with unsupported firmware
causes an uncertified condition to exist on the array. See the following procedure
for more information.
