Installing the enclosures
Installation checklist
The following table outlines the steps required to install the enclosures and initially configure the system. To ensure a
successful installation, perform the tasks in the order they are presented.
Table 2 Installation checklist
Step
Task
1.
Install the controller enclosure and optional
drive enclosures in the rack, and attach the
bezel or ear caps.
2.
Connect the controller enclosure and LFF/SFF
drive enclosures.
3.
Connect power cords.
4.
Test enclosure connections.
5.
Install required host software.
6.
Connect data hosts.
7.
Connect remote management hosts.
8.
Obtain IP values and set management port IP
properties on the controller enclosure.
9.
Perform initial configuration tasks
•
Sign in to the web-based Storage
Management Utility (SMU).
•
Initially configure and provision the storage
system using the SMU.

Connecting controller and drive enclosures
MSA 1050 controller enclosures support up to four enclosures (including the controller enclosure). You can cable drive
enclosures of the same type or of mixed LFF/SFF model type.
The firmware supports both straight-through and fault-tolerant SAS cabling. Fault-tolerant cabling allows any drive
enclosure to fail—or be removed—while maintaining access to other enclosures. Straight-through cabling does not
provide the same level of fault-tolerance as fault-tolerant cabling, but does provide some performance benefits as well as
ensuring that all disks are visible to the array. Fault tolerance and performance requirements determine whether to
optimize the configuration for high availability or high performance when cabling. MSA 1050 controller enclosures
support 12 Gb/s disk drives downshifted to 6 Gb/s. Each enclosure has an expansion port using 6 Gb/s SAS lanes. When
connecting multiple drive enclosures, use fault-tolerant cabling to ensure the highest level of fault tolerance.
For example, the illustration on the left in
module 2A, with a chain of connections cascading down (blue). Controller module 1B is connected to the lower
expansion module (4B) of the last drive enclosure, with connections moving in the opposite direction (green).
