Chapter 2. Introduction to IBM Flex System V7000 Storage Node 

Draft Document for Review January 29, 2013 12:52 pm

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 see the InfoCenter website for 
details at:

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 (as 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 which 
changes the HD mini SAS to the mini SAS connection that is on the expansion. Figure 2-12 
on page 56 shows the cabling scheme and the differences in the cable connections of the two 
expansions.
