300 GB 15 000 RPM SAS drive
The IBM MK3001GRRB is a 2.5-inch internal hard drive built for enterprise servers and storage arrays. It spins at 15 000 RPM and connects through a 6 Gb/s SAS interface with a 64 MB cache. A hot-swap caddy is included for quick installation in compatible SYSTEM X bays. The 300 GB capacity suits transactional workloads that demand low latency.
Suits high-IOPS server workloads
Database administrators and virtualization hosts benefit from the 15 000 RPM spindle speed and SAS dual-port architecture. The drive is not for desktop PCs or laptops that lack a SAS backplane and hot-swap infrastructure. It also does not meet the needs of users who require terabyte-scale capacity in a single bay. Cooling and power delivery must match enterprise chassis specifications.
6 Gb/s SAS interface decides fit
The single specification that determines compatibility is the 6 Gb/s SAS interface; the host controller and backplane must support this signalling rate and the 2.5-inch hot-swap form factor. Without a SAS-enabled server chassis the drive cannot be used. Verify the part numbers 81Y9670, 81Y9671 and 81Y3812 against your system documentation before purchase.

Domande su questo articolo
How does the 15000 RPM speed affect real-world server performance?
The 15000 RPM spindle delivers low latency and high sustained throughput for transaction-heavy workloads such as databases and virtualisation hosts.
What does the SAS 6Gb/s interface limit in practice?
The SAS 6Gb/s link caps maximum transfer rate at 6 Gbit/s per port, so sequential reads and writes cannot exceed that bandwidth ceiling.
Will the included SYSTEM X caddy fit a standard 2.5 inch drive bay?
Yes, the supplied SYSTEM X caddy adapts the 2.5 inch drive to the hot-swap tray used in compatible IBM System x servers.
