Chapter 2. Introduction to IBM Flex System V7000 Storage Node 55
Figure 2-11 shows the front view of the 2076-224 enclosure.

The drives are positioned in one row of 24 vertically mounted row in the drive assemblies. The
drive slots are numbered 1 - 24, starting from the left. (There is a vertical center drive bay
molding between slots 12 and 13.)
Though the IBM Storwize V7000 2076-224 enclosure is a 2.5 inch, 24 drive slot chassis; the
drives of this subsystem are not interchangeable with the IBM Flex System V7000 Storage
Node drives. Both drives use a different carrier and contain a different product identifier in
their code.
Therefore, the IBM Storwize V7000 expansions support their own drive types in their
enclosures and should be created in their own configurations and storage pools when used
with the IBM Flex System V7000 Storage Node.
IBM Flex System V7000 Storage Node enclosures currently support SSD, SAS, and Nearline
SAS drive types. Each SAS drive has two ports (two PHYs) and I/O can be issued down both
paths simultaneously.
For a list of supported drives for the IBM Storwize V7000 and other details, see the

2.4.5 SAS cabling requirements
The IBM Flex System V7000 Storage Node uses new smaller SAS2 cable connectors. These
connectors are based on the high density (HD) mini SAS connectors.
For the connections between the IBM Flex System V7000 Control enclosure and the IBM Flex
System V7000 Expansion enclosure in the chassis, you have to use these short cables
(shown in Figure 2-2 on page 43) that can be ordered with your storage.
With the addition of external IBM Storwize V7000 expansion, there is an adapter that changes
the HD mini SAS to the mini SAS connection that is on the expansion. Figure 2-12 shows the
cabling scheme and the differences in the cable connections of the two expansions.
