Product Description
The IBM 81Y9878 is a 3TB 7,200 RPM SAS 6Gb/s hot-swap LFF 3.5-inch enterprise nearline hard disk drive.
7.2K RPM nearline SAS is best for sequential workloads including backup, archive, data warehouse loading, and large file storage.
SAS provides better reliability, enterprise management features, and dual-port connectivity versus SATA at high capacity tiers.
Yes, the IBM 81Y9878 supports hot-swap replacement for zero-downtime drive management in IBM server 3.5-inch RAID arrays.
The IBM 81Y9878 is certified for IBM System x servers with 3.5-inch LFF hot-swap drive bays; verify specific model compatibility.
The IBM 81Y9878 is a 3 Terabyte 7,200 RPM SAS 6Gb/s hot-swap LFF 3.5-inch enterprise hard disk drive certified for IBM System x servers, providing very high capacity storage per drive bay for data-intensive storage applications. At 3TB capacity, this drive offers enterprise IT teams the ability to store large volumes of business data, backup images, archive content, and log files within IBM server storage arrays while maintaining the management and reliability advantages of the SAS interface over SATA alternatives in enterprise environments.
The 7,200 RPM spindle speed and SAS 6Gb/s interface of the IBM 81Y9878 deliver strong sequential read and write throughput suited for workloads characterized by large block sequential access patterns including backup streams, large file transfers, video content storage, and data warehouse loading operations. While 7,200 RPM nearline SAS drives do not match the random I/O performance of 10K or 15K RPM drives, their superior capacity per drive makes them the optimal choice for high-capacity storage tiers within IBM server RAID arrays.
IBM certification ensures the 81Y9878 is validated for IBM System x server SAS backplanes and ServeRAID RAID controllers, providing the management visibility through IBM IMM and ServeRAID storage management tools required for enterprise storage administration. The hot-swap LFF 3.5-inch design supports live drive replacement in IBM System x 4U and larger servers equipped with 3.5-inch hot-swap drive bays, enabling seamless replacement of drives in high-capacity RAID arrays without disrupting ongoing backup or archival operations.
