2 TB SAS drive for Dell PowerEdge servers

This 3.5-inch enterprise hard drive delivers 2000 GB of storage on a 6 Gb/s SAS interface. It spins at 7200 RPM with a 128 MB cache and ships with an R-series tray for direct installation in compatible Dell PowerEdge chassis. The drive is new and carries a one-year warranty.

Replaces slower or smaller SAS drives in Dell arrays

Moving from a 7.2 K RPM drive with less capacity or a 3 Gb/s SAS model gives a clear boost in throughput and space. The jump is worth it when current volumes are full or when batch workloads stall on the older spindle speed. No benefit appears if the controller cannot use 6 Gb/s signalling.

Handles bulk data, logs

2000 GB comfortably stores months of application logs, virtual-disk images or nightly backups. The 128 MB cache absorbs write bursts from RAID rebuilds or database checkpoints. Sustained random I/O will saturate the spindle before the interface, so heavy transaction workloads need faster media.

Perguntas sobre este artigo

What drive-bay width and tray type does the ST2000NM0023 require?

The drive uses a 3.5 inch form factor and ships with an R-series caddy that slides into compatible Dell PowerEdge bays.

How is the SAS drive installed in a PowerEdge server and what step is often missed?

Insert the supplied tray until the latch clicks, then connect the SAS data and power cables; the step often missed is fully seating the latch so the drive is recognised.

When should the 128 MB cache drive be replaced in a RAID array?

Replace the drive if SMART reports reallocated sectors, sustained read errors, or if the array controller flags it as failed during patrol reads.
