What performance specs does the IBM 49Y6139 SSD provide?

The 49Y6139 delivers 500 MB/s sequential read/write speeds, 100,000 4KB random read IOPS, and 50,000 4KB random write IOPS via 6Gbit/s SAS interface. MLC NAND with 16 internal channels ensures sustained performance for enterprise mixed workloads like databases and virtualization.

Is the 49Y6139 suitable for hot-swap server deployments?

Yes, this 2.5-inch SFF SSD is hot-swappable (G2HS design), allowing replacement without system downtime. It integrates seamlessly with IBM System x and Lenovo servers using Optimus SAS controllers, supporting high-availability environments.

What security and reliability features are included?

Features 256-bit AES encryption, S.M.A.R.T. monitoring, and power-loss protection. Enterprise MLC technology provides high endurance for read/write-intensive tasks, with 24nm lithography for efficiency and reliability in data centers.

What are the physical dimensions and operating conditions?

Measures 70mm width, 100mm depth, 6.8mm height, weighs 122g. Operates 0-70°C, 8-85% RH non-condensing, up to 3,050m altitude, ideal for standard rack servers.

Which workloads benefit most from this SSD?

Optimized for databases, data warehouses, caching/tiering, email systems, and virtualization. High IOPS and throughput handle random I/O patterns efficiently, reducing latency in high-density server deployments.

Does it support IBM/Lenovo server compatibility?

Designed for IBM System x servers and Lenovo equivalents with SAS capability, specifically any Optimus SAS controllers. Functions as field-replaceable unit (FRU) for seamless integration in enterprise storage configurations.
