Introduction
IBM® Solid State Drives (SSDs) use nonvolatile flash memory rather than spinning magnetic media to store data. Designed for enterprise blades and servers, the SSDs leverage the extensive history of IBM of meeting enterprise customer expectations in product development, qualification, and ongoing support on a worldwide basis. IBM offers the highest quality enterprise storage devices for enterprise computing environments.
IBM SSDs deliver the performance, power, size, and reliability required for IBM BladeCenter® and IBM System x® application servers. For cost-effective reliability and endurance, and to let customers chose the correct drive to meet business requirements, the IBM SSD family offers both SLC and enterprise-grade MLC technology. With up to 200 GB capacity in a 1.8-inch form factor, this powerful drive provides data loss protection upon power failure. In addition, IBM SSDs support the SATA interface, meaning that there are no compatibility issues. Figure 1 shows a 1.8" solid state drive.

Did you know?
In terms of I/O operations per second, SSDs can be used in enterprise environments to replace multiple traditional spinning disks, thereby improving application performance, power consumption, reliability, and the total cost of ownership. However, SSDs can also be used as a fast virtual memory paging device to reduce the need for more expensive memory DIMMs, which can lead to reduced server acquisition costs.
SSDs simplify local storage infrastructure to help maintain overall maintenance and cooling cost, while providing remote storage solutions for end-to-end data availability as part of the enterprise ecosystem. SSDs are an appropriate solution for local OS booting, read-intensive applications, and some local storage space. Having originally been developed for the telco and federal marketplace, these SATA-based drives are highly rugged and reliable, and consume very low power. Increasingly, solid state storage is becoming a practical component in balancing datacenter cost, reliability, and manageability.

SSD technology
SSDs differ from traditional hard disk drives (HDDs) in many ways, but there is one key difference: no moving parts. Where HDDs contain spinning disks and movable heads that read and write data on the disks, SDDs use solid-state (chip-based) memory to store data. This difference provides SSDs with the following advantages over HDDs:
SSDs use NAND-based nonvolatile flash memory, the same technology used by USB storage devices, memory cards, mobile phones, and other portable electronic devices that require data storage. However, the type of NAND flash memory that an SSD employs for data storage and retrieval is a key factor for determining the appropriate environment for which the device is employed. Where one methodology might be adequate for the type of usage and environment that the device is intended for (such as a laptop model designed for the consumer market), it might not be feasible for enterprise-class markets where high-performance standards and reliability are key factors for data storage.
Two methods currently exist for facilitating NAND flash memory: single-level cell (SLC) and multi-level cell (MLC). The following sections provide information about each of these technologies.
Single-level cell (SLC) SSDs
SLC flash memory stores data in arrays of floating-gate transistors, or cells, 1 bit of data to each cell. This single bit per cell methodology results in faster transfer speeds, higher reliability, and lower power consumption than that provided by HDDs. SLC SSDs are two-to-three times more expensive to manufacture than MLC devices.
Multi-level cell (MLC) SSDs
The basic difference between SLC flash memory and MLC flash memory technologies is storage density. In comparison with SLC flash memory, which allows only two states to be stored in a cell, thereby storing only one bit of data per cell, MLC flash memory is capable of storing up to four states per cell, yielding two bits of data stored per cell.
Tables 2 and 3 illustrate the differences.
Table 2. SLC single-bit flash memory states
Table 3. MLC dual-bit flash memory states
MLC flash memory can be further delineated into two categories:
Both cMLC and eMLC flash memory have the advantage of higher data density and the resultant lower cost-per-bit ratio. For practical reasons, this is where the similarities end. The high-density storage model employed by both technologies results in lower write endurance ratios and higher rates of cell degradation than SLC flash memory, greatly reducing the lifetime of the device. For cMLC devices, this does not pose any issues, as the lifetime expectancies are considered adequate for consumer-grade devices. This makes cMLC flash memory ideal for lower-cost, consumer-targeted devices such as memory cards and mobile devices, where cost and market factors outweigh performance and durability.
eMLC provides longer endurance through trimming of components and optimizing certain parameters in the firmware. In addition, eMLC SSDs employ over-provisioning data storage capacity and wear-leveling algorithms that evenly distribute data when the drives are not being heavily utilized. This results in a sixfold increase in write cycles and reduced concerns about cell degradation. While it does not yet match the performance and durability SLC flash memory, it still exceeds lifetime expectancy requirements for enterprise applications.
For industries where enterprise performance and durability is essential, IBM SSDs employ eMLC NAND flash memory to leverage the cost-effective characteristics of MLC flash memory with the performance and reliability of SLC technology.
Table 4 shows the NAND flash memory types used in each currently available SSD option.

MLC flash memory can be further delineated into two categories:
- Consumer-grade MLC (cMLC): Used in consumer (single user) devices such as USB storage devices, memory cards, mobile phones, and so on.
- Enterprise-grade MLC (eMLC): Designed specifically for use in commercial (multiple-user) enterprise environments.
Both cMLC and eMLC flash memory have the advantage of higher data density and the resultant lower cost-per-bit ratio. For practical reasons, this is where the similarities end.

Features and benefits
Table 5 provides a summary of the advantages and disadvantages of SLC and MLC flash. As shown in Table 3, the IBM SSD options are all either SLC or eMLC. As a result, the feature discussions below apply to those technologies and not cMLC.
Table 5. Benefits of SLC and MLC
High-density storage
As explained in the previous section, the MLC flash memory methods employ multiple bit-per-cell technology, thus resulting in higher data density compared to SLC technology. This means that drives are available in larger capacities.
Cost per bit
At present, HDD storage still has a clear pricing advantage, with a cost per gigabyte ratio as high as 1:10 compared with SDD storage, depending on factors such as drive size, array configuration, and the type of NAND flash memory used (SLC flash cost-per-bit is three times as much as MLC flash). However, this gap has been closing as SDD technology becomes less expensive and more prevalent.
One solution to offset costs is to use SDDs for server drives that only perform the most I/O-intensive operations, such as boot drives, caching, and swap space. This provides lower latency rates and higher throughput for application-critical operations. SDDs can also be employed in RAID arrays for fault tolerance and data sharing.
Durability
Because flash memory does not have the mechanical limitations of traditional spinning hard drives, SSDs are less susceptible to shock and vibration and have a higher tolerance for wide temperature and humidity ranges.
Low power consumption
Replacing HDDs with SSDs results in a lower cost and greener enterprise. Because there are fewer storage devices needed, fewer resources (such as controllers, switches, and racks) are needed, resulting in:
These reductions result in an overall lower total cost of ownership.
Performance
Because there are no moving parts, startup times are small because no spin-up or seek time is required. For example, when an HDD retrieves a large file, it searches for the file in passes with each revolution of the spinning disk, resulting in access times of 10 - 15 ms on average. An SSD can retrieve the same file as quickly as 0.1 ms. This makes SDD server usage ideal for applications where throughput is more important than capacity, such as video distribution and financial analysis.
The improved application performance of SSDs results in increased and more reliable transactions in less time. A comparison of IBM high-performance SSDs with traditional enterprise-level HDDs demonstrates a dramatic increase in overall I/O operations per second (IOPS), as shown in Table 6.
Table 6. IOPS comparison
Note: All results with 4 K block transfers
Stated another way, if your application's demands can be met by implementing a large RAID array of HDDs, you can use far fewer SSDs and achieve the same performance.
Data reliability
SLC and eMLC solid-state drives utilize several techniques to ensure data stability and retention:
SATA
Migrating your enterprise storage to SSD is relatively painless because solid state drives support the SATA protocol used by HDDs. Coexistence is also possible because of this. Figure 2 shows the x3690 X5 with 1.8-inch SSDs and 2.5-inch SAS drive bays.

- A smaller footprint in the enterprise
- Quieter operation
- Reduced cooling requirements

| Read IOPS | 390 | 300 | 4000 | 30,000 |
| Cost per IOPS ($) | $0.52 (146 GB) | $0.83 (146 GB) | $0.09 (50 GB) | $0.04 (50 GB) |
Stated another way, if your application's demands can be met by implementing a large RAID array of HDDs, you can use far fewer SSDs and achieve the same performance.
Data reliability
SLC and eMLC solid-state drives utilize several techniques to ensure data stability and retention:
- Wear-leveling algorithms that evenly distribute data across the drive.
- Garbage collection that uses an algorithm to select the blocks in the memory to erase and rewrite.
- For correctable errors, the drives use an ECC scheme (twenty-four 9-bit symbols using Reed Solomon).
- For uncorrectable errors, the drives use the Redundant Array of Independent Silicon Elements (RAISE) scheme, which allows the controller to rebuild data that was located on a failed flash page or block somewhere else on the drive.
- For undetectable errors, there is data path protection (CRC-32 bit).
