HP 600GB 10000 RPM SAS Enterprise Drive

This HP 581286-B21 is a 2.5 inch enterprise hard drive with a 600GB capacity and 10000 RPM spindle speed. It uses a SAS 6Gb/s interface and fits a 9.5mm height bay. The drive is designed for high-transaction server workloads.

Suited for servers needing fast SAS storage.

This drive suits administrators deploying 2.5 inch SAS drives in HP server chassis or compatible hot-plug carriers. Builders assembling standard desktop PCs or workstations requiring consumer drive form factors should look elsewhere. The SAS interface requires a compatible controller or backplane.

Single spec that decides fit: SAS 6Gb/s interface

The SAS 6Gb/s interface is the decisive specification; the drive will only function with a SAS host bus adapter or RAID controller that supports this signalling rate. Verify your server or storage array accepts 2.5 inch SAS drives before purchase.

Questions about this item

What drive-bay height and width does the 2.5 inch 581286-B21 require?

The drive fits a standard 2.5 inch bay with a maximum height of 9.5 mm and a maximum width of 69.75 mm.

How is the SAS 6Gb/s drive installed, and what step is often missed?

Slide the drive into the hot-plug carrier until the connector seats firmly, then lock the carrier latch; the step often missed is fully engaging the latch so the drive registers on the SAS bus.

When should the 600 GB 10000 RPM enterprise drive be replaced in a server array?

Replace the drive when SMART reports reallocated sectors, predictive-failure alerts, or when the array controller flags it as degraded during routine patrol reads.
