Installing a control enclosure and one or more expansion enclosures
If you are installing a control enclosure plus one or more expansion enclosures, follow these guidelines.
• A Lenovo Storage V7000 system can support up to 1056 drives installed into control and expansion
enclosures. Each enclosure requires 2U of rack space.
• Each assembled enclosure weighs more than 36 kg. Provide sufficient space at the front of the rack
for three persons to carry the enclosure safely.
• Each system can consist of up to four control enclosures. Each control enclosure can be connected to up
to 20 expansion enclosures (two SAS chains of up to 10 expansion enclosures each).
• For best performance, dived the total number of expansion enclosures to be installed between each
control enclosure in the system.
• Where expansion enclosures are to be installed, distribute them evenly into rack space above and below
the control enclosure to which they will connect. Do not leave gaps between the enclosures. This aids
cabling and serviceability.
• Leave space in the rack for future expansion enclosures, but otherwise install all enclosures that constitute
one system in adjacent or nearby rack space.
• 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.
Adding an expansion enclosure chain to an existing system
If you are adding an expansion enclosure chain to an existing Storage V5030 system, follow these guidelines.
• You do not need to power off the system. You can add an expansion enclosure while the system is
operational.
• Add the first expansion enclosure directly below the control enclosure.
• Add the second expansion enclosure directly above the control enclosure.
• Add the third expansion enclosure directly below the first.
• Add the fourth expansion directly above the second, and so on.
