A Lenovo Storage V7000 system
consists of one or more machine type 2076 rack-mounted enclosures. Control enclosures contain the node canisters that manage the system
operation and provide the host interfaces. Expansion enclosures provide more extra drives that can be managed
by the system. Enclosures can support 2.5 inch (6.35 cm) small
form factor drives or 3.5 inch (8.89 cm) large form factor drives.
There are several model types. The main
differences among the model types are the following items:
- Whether the model is Gen1 or the newer Gen2
Lenovo Storage V series Gen1 refers to the enclosure models in the
following table:

| Machine type/model |
Description |
| 2076-524 |
Lenovo Storage V series control enclosure, with up to 24 2.5-inch (6.35 cm) drives |
| 2076-12F |
Lenovo Storage V series expansion enclosure for up to 12 3.5-inch (8.89 cm) drives |
| 2076-24F |

- The number of drives that an enclosure can hold
Drives are on
the front of the enclosure. An enclosure can hold up to twelve 3.5-inch
drives or up to twenty-four 2.5-inch drives.
- Whether the model is a control enclosure or an expansion enclosure
Control enclosures contain the main processing units that control
the whole system. They are where external systems, such as host application
servers, other storage systems, and management workstations are connected
through the Ethernet ports or Fibre Channel ports. Control enclosures
can also be connected to expansion enclosures through the serial-attached
SCSI (SAS) ports.
Expansion enclosures contain more storage
capacity. Expansion enclosures connect either to control enclosures
or to other expansion enclosures through the SAS ports.
- If the control enclosure has either 1 Gbps Ethernet capability
or 10 Gbps Ethernet capability
The machine type and model (MTM) are shown
on labels on the front and the rear of each enclosure:
- The left end cap label on the front of the enclosure indicates
whether the enclosure is a control enclosure or an expansion enclosure.
- The label on the rear of the left enclosure flange.
Note: Labels also show the enclosure serial number. You must
know the serial number when you contact IBM support.
You must be able to distinguish between
control enclosures and expansion enclosures before you service the
system. Be aware of the following differences:
- The model type that is shown on the labels.
- The model description that is shown on the left end cap.
- The number of ports at the rear of the enclosure.
Control enclosures have Ethernet ports, Fibre Channel ports, and USB
ports. Expansion enclosures do not have any of these ports.
