Expansion enclosures
An IBM® FlashSystem 5600 can be expanded beyond the capacity in the control enclosure by using expansion enclosures. This can be used to implement a tiered storage system.
| Machine Type - Model | Description | Minimum software level |
|---|---|---|
| 4662-12G | 2U12 SAS Expansion Enclosure with Expert Care | 9.1.2 |
| 4662-92G | 5U92 SAS Expansion Enclosure with Expert Care | 9.1.2 |
The IBM FlashSystem 5600 requires the SAS Expansion network adapter card feature to connect to SAS expansions. This card supports two independent cascaded chains of expansion enclosures.
The system supports specific combinations of SAS expansion enclosures, based on the capacity of each of the enclosures.
High-density enclosures and standard-density enclosures can be supported within a chain, based on the following rules:
- A chain can have any combination of expansions up to 12 rack units (12U) of space.
- Standard-density expansion enclosure are 2U each.
- High-density expansion enclosures are 5U each.
| Expansion enclosures types | Valid combinations | ||
|---|---|---|---|
| 5U expansion enclosures | 0 | 1 | 2 |
| 2U expansion enclosures | 0-6 | 0-3 | 0-1 |
Supported Drives for IBM FlashSystem 5600 expansion enclosures
The following tables provide the list of supported drives for IBM FlashSystem 5600 SAS expansion enclosures.
All drives are dual-port and hot-swappable. Drives of the same form factor and connector type can be intermixed within an enclosure, however an Array must use drives of the same type.
| Drive type | Capacities supported |
|---|---|
| 3.5 inch 7.2K RPM Nearline hard drive (SAS) | 12 TB, 16 TB, 20 TB and 24 TB |
