  • Supplied with PowerEdge caddy for immediate installation in listed systems

Dell SAS Drive for PowerEdge Servers

This 2.5-inch internal hard drive delivers 900GB of storage on a SAS 6Gb/s interface. It spins at 10000RPM with a 64MB cache and ships new with a Dell PowerEdge caddy included. The drive carries the ST9900805SS model number and is listed at zero hours of operation.

Suits PowerEdge arrays needing 10K SAS spindles

IT teams populating compatible PowerEdge M, R and T series servers with 2.5-inch SAS bays will find a direct fit. The tray is supplied, so no separate bracket purchase is required. Buyers who need a different interface protocol or higher capacity per spindle should look at other drives.

10000RPM rotational speed

The 10K RPM spindle is the defining spec for random I/O latency in transactional workloads. If the application requires that mechanical speed tier, this drive matches it; if a slower or faster spindle is specified, this unit will not meet the requirement.

Pitanja o ovom artiklu

What does the SAS 6Gb/s interface cap the transfer rate at in practice?

The 6Gb/s SAS link limits sustained throughput to roughly 600 MB/s, so the 10000RPM platters and 64MB cache cannot push data faster than that ceiling.

What physical space and mounting hardware does the 2.5" drive need to fit in a server?

It requires a 2.5" SFF bay and ships with a Dell PowerEdge caddy/tray that slides directly into compatible M-series and R-series chassis.

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

Snap the supplied caddy onto the drive, insert the assembly into the hot-swap bay until the latch clicks, then verify the controller detects the 900GB volume before initializing the array.
