With the Lustre DNE configuration option, shown in Figure 5, the two Dell PowerEdge R730 servers will
be configured in an active/active, highly available cluster. Each server will be directly attached to two
(2) Dell PowerVault MD3420 storage arrays. One MD3420 will house the Lustre MGT as well as one of the
MDT while the second MD3420 will house the second MDT. The servers will be configured such that each
server will be primary for one MDT while secondary for the other MDT. Both MD3420 will be fully
populated with 24 – 300GB, 15K RPM, 2.5” SAS drives configured in a 22 disk RAID10 with 2 hot spares.
The Lustre DNE option will effectively double the space available for file system metadata and the
number of files that can be served.
