IBM High IOPS SSD PCIe Adapters

IBM System x at-a-glance guide

The IBM High IOPS SSD PCIe Adapters provide a new generation of ultra-high-performance storage
based on solid state device technology for System x and BladeCenter. These adapters are alternatives to
disk drives and are available in several sizes, from 160 GB to 1.2 TB. Designed for high-performance
servers and computing appliances, these adapters deliver throughput of up to 300,000 I/O operations per
second (IOPS), while providing the added benefits of lower power, cooling, and management overhead,
and a smaller storage footprint.

The IBM 320GB High IOPS SSD PCIe Adapter is shown in Figure 1.

Did You Know?

These adapters use flash memory as the storage medium, contain no moving parts, and do not have the
issues associated with vibration, noise, and mechanical failure. The adapters are built as block devices on
a PCIe bus with advanced wear-leveling, advanced ECC, and N+1 chip-level redundancy, providing
unparalleled reliability and efficiency.

Features

Based on standard PCIe architecture coupled with silicon-based NAND clustering storage technology, the
High IOPS Adapters are optimized for System x racks and can be deployed in blades via the PCIe
expansion units. These scalable designs come with both Single Level Cell (SLC) and MultiLevel Cell
(MLC) technologies in standard PCIe form factors. While MLC offers a cost-effective alternative, SLC
provides over 12X more endurance and up to 30% better performance over MLC.

These adapters use NAND flash memory as the basic building block of solid-state storage and contain no
moving parts, thus 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
N+1 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

The IBM High IOPS SSD PCIe Adapters have the following features:

Performance features :



High performance - 230 times better IOPS. That means, for example, 97,014 IOPS at 4K block
random reads versus 420 IOPS for a 15K RPM 146GB disk drive.



Low latency of 50 μs - 1% of the latency of a 15K RPM 146GB disk drive.



600 MB/s random writes sustained.

Reliability features:



Predictable lifetime.



Up to 25 years of data retention.



N+1 redundancy built-in to ensure data protection



Available in SLC or MLC



11-bit ECC protection.



Advance bad-block management algorithms enable taking blocks out of service when their failure rate
becomes unacceptable.



IBM High IOPS Launch Manager management suite.

Energy efficiency features :



Low power consumption for performance: 9W delivering 100,000 IOPS versus 5.5W for 420 IOPS
from a 15K RPM 146GB disk drive.



Only 57 kWh/yr at 100,000 IOPS sustained.
