18 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
The use of SAS connector 1 is mandatory because the expansion enclosure must be
attached to a control enclosure or another expansion enclosure further up in the chain. SAS
connector 2 is optional because it is used to attach to further expansion enclosures down the
chain.
The Storwize V5010 and Storwize V5020 support a single chain of up to 10 expansion
enclosures that attach to the control enclosure. The Storwize V5030 supports up to 40
expansion enclosures in a configuration that consists of two control enclosures, which are
each attached to 20 expansion enclosures in two separate chains.
Table 1-9 shows the maximum number of supported expansion enclosures and the drive
limits for each model.
Table 1-9 Expansion enclosure and drive limits
Each port includes two LEDs to show the status. The first LED indicates the link status and
the second LED indicates the fault status.

1.5.6 Host interface cards
All IBM Storwize V5000 Gen2 support Ethernet ports as standard for iSCSI connectivity. For
the Storwize V5010 and Storwize V5020, these Ethernet ports are 1 GbE ports. For the
Storwize V5030, these Ethernet ports are 10 GbE ports. The Storwize V5020 also includes
12 Gb SAS ports for host connectivity as a standard.
Additional host connectivity options are available through an optional adapter card.
Table 1-10 shows the available configurations for a single control enclosure.

Maximum number of supported expansion enclosures 010 010 0040
Maximum number of supported drives 392 392 1520
Restriction: The IBM Storwize V5000 Gen2 expansion enclosures can be used only with
an IBM Storwize V5000 Gen2 control enclosure. The IBM Storwize V5000 Gen1 expansion
enclosures cannot be used with an IBM Storwize V5000 Gen2 control enclosure.
