PS6210 Hardware Owner's Manual 1 Basic Storage Array Information Shutting Down and Restarting an Array A PS Series array includes redundant, hot-swappable drives, power supplies, and control modules (in a dual control module array). You can remove a redundant component without affecting operation if a functioning component is available. Otherwise, Dell recommends that you cleanly shut down the array and turn off power before removing a component.
2 Maintaining Drives You can replace a failed drive while the array remains running. About Drive Types Depending on your configuration, your array supports up to 24 2.5-inch SAS and SSD drives or up to 24 3.5-inch SAS or NL-SAS drives in internal drive bays. Drives are connected to a backplane through drive carriers and are hot-swappable. Drives are supplied in a carrier that is keyed to fit into specific array models, and cannot be installed in other Dell arrays, or arrays not from Dell Inc.

PS6210 Hardware Owner's Manual 2 Maintaining Drives If a Spare Drive Is Not Available If a spare drive is not available, the RAID set will become degraded and performance might be impaired. However, a RAID 6 set can survive two simultaneous drive failures. If a spare drive is not available and the failed drive is in a RAID set that is already degraded, data might be lost and must be recovered from a backup.
PS6210 Hardware Owner's Manual 2 Maintaining Drives For example, when you install a drive, the timer starts. If you install another drive before 2 minutes have elapsed, the timer is restarted. If no other drives are installed, the drive is configured after a delay of 2 minutes. • If you install a drive during RAID reconstruction or verification, the new drive will not be configured until the operation completes. Removing a 2.5-inch Drive 1. Remove the bezel. See Removing the Bezel on page 2. 2.

3 Maintaining Control Modules Different PS Series array models contain different control module types. The combination of chassis type, control module pair, and drives determines the PS Series array model number. The control modules in a PS Series array contain the PS Series firmware, which provides the Group Manager GUI, the command line interface, and all the array and storage management functions and features.
PS6210 Hardware Owner's Manual 3 Maintaining Control Modules Only one control module is active (providing disk access and serving network traffic) at one time. The secondary (redundant) control module mirrors cache data from the active control module. If the active control module fails, all functions of the primary controller transfer to the secondary. Dual Controller Configuration A dual control module configuration eliminates a single point of failure in the array.
