IBM High IOPS MLC Adapters 3
Features
Based on the standard PCIe architecture coupled with silicon-based NAND clustering storage technology,
the High IOPS MLC Adapters are optimized for System x rack servers and can be deployed in blades
through the PCIe expansion units. These scalable designs come with cost-effective Multi-Level Cell
(MLC) technology in standard PCIe form factors.
These adapters use NAND flash memory as the basic building block of solid-state storage and contain no
moving parts, so they are less sensitive to issues associated with vibration, noise, and mechanical failure.
These adapters are built as block devices on a PCIe bus with advanced wear-leveling, ECC, and
chip-level redundancy providing unparalleled reliability and efficiency.
Typical uses are applications with ultra-high performance I/O needs:
Data-in-memory applications
Medium to large databases
Cache
Video
Data warehousing
Business intelligence and analytics
Decision support
