v Storwize V5010 and Storwize V5020 control enclosures systems can support up
to 10 expansion enclosures on one chain. Storwize V5030 and Storwize V5030F
systems can support two chains and each chain can support up to 10 expansion
enclosures.
v If a rack is to be only partially filled, install the enclosures low enough for the
rack to remain stable and enable easy access to the enclosures for servicing.
