HP StorageWorks IO Accelerator for HP BladeSystem c-Class |
|
HP is introducing the IO Accelerator as part of a comprehensive solid state storage portfolio. This storage device is targeted for markets & applications requiring high transaction rates and real-time data access that will benefit from application performance enhancement. The HP IO Accelerator brings high random I/O performance and low latency access to storage, with the reliability of solid state technology and its low power and cooling requirements. This product, based on NAND Single Level Cell and Multi Level Cell flash technology (depending on capacity) is available in a mezzanine card form factor for HP BladeSystem c-Class. |

What's New
|
| Solid State Storage
Technology can provide customer benefits in several different areas and
with different architecture implementations. It offers high performance
and reliability with no moving parts, low power and cooling requirements
and improved environmental tolerance. Solid state storage technology has
only recently become a popular topic in the market despite the fact that
it has been used in some enterprise applications for a number of years,
especially where the workloads benefit significantly from very low latency
access, and application benefits exceed the costs associated with the solution. Solid state storage technology benefits are best realized with latency-sensitive environments for both read- and write- intensive workloads. In addition, significant operational cost savings can be seen by the customer when this technology is applied to the right applications. Some use cases are:
As an I/O card, the IO Accelerator is not a typical SSD; rather it is attached directly to the server's PCI Express fabric to offer extremely low latency and high bandwidth. The card is also designed to offer high IOPs (I/O Operations Per Second) and nearly symmetric read/write performance. The IO Accelerator uses a dedicated PCI Express x4 link with nearly 800MB/s of usable bandwidth. Each mezzanine slot in the c-Class BladeSystem offers at least that amount of bandwidth, so by combining cards, you can easily scale the storage to match your application's bandwidth needs. The HP IO Accelerator's driver and firmware provide a block-storage interface to the operating system that can easily be used in the place of legacy disk storage. The storage can be used as a raw disk device, or it can be partitioned and formatted with standard file systems. You can also combine multiple cards using OS RAID (up to 3 with a full-height c-Class blade server) for increased reliability, capacity or performance in a single blade server. A unique feature of the IO Accelerator is the ability for the customer to format it with a lower-than-stated capacity in order to achieve even greater sustained write performance. For instance, an 80GB drive could be formatted as a 40GB drive using the low-level fio-format tool. This will give improved write performance for some applications. Each customer's results may vary. The HP IO Accelerator mezzanine card differs from other c-Class mezzanine cards in that it does not connect to any c-Class Interconnect Module. This allows the use of the IO Accelerator in any open mezzanine slot in a c-Class chassis regardless of what types of Interconnect Modules might be installed. |

| What is an IO Accelerator? |
The IO Accelerator is an advanced storage device that
uses solid state storage technology directly on the PCI bus, assuring
high read and write data rates and accelerated application performance.
The associated application performance improvements will have a positive
impact on business results and the ability to make decisions quickly,
resulting in significant cost and time savings.
|
|
|
|
| Single Level Cell and Multilevel Cell |
NAND technology uses flash memory cells to store data. Single level Cell (SLC) stores one bit per cell, while Multi-level Cell (MLC) uses two bits per cell. While MLC can store more data within each device, it has lower endurance characteristics than SLC. |
|
|
|
| IO and Read/Write Performance |
HP StorageWorks IO Accelerator offers superior IO performance (up to 100,000 IOPs), and high read (up to 700MB/s) and write (up to 600 MB/s) performance with SLC models. |
|
|
|
| Latency |
HP StorageWorks IO Accelerator offers very low latency access to data (as low as 50 microseconds to read a 4K block), in other words a virtually zero seek time compared to rotating magnetic media. |

| RAM Requirements | The amount of free RAM required by the driver depends on the size of the blocks used when writing to the drive. The smaller the blocks, the more RAM required. Here are the guidelines for each 80GB of storage: | |
| Average Block Size(bytes) | RAM usage (Megabytes) | |
| 8,192 | 400 | |
| 4,096
| 800 | |
| 2,048
| 1,500 | |
| 1,024
| 2,900 | |
| 512 | 5,600 | |

|
| PCI IDs |
Vendor & Device ID 1AED:1003; Subsystem Vendor & Device ID 103C:324D |
|
|
|
| Upgradability |
The IO Accelerator's controller can be upgraded in the future with new firmware. Online firmware update tools are available for all supported operating systems. |
|
|
|
| Wear-leveling |
Projected lifetime of the NAND storage due to wear-out exceeds 15 years for all devices, based on a 5TB write & erase per day usage model. |
|
|
|
| Data Integrity |
Using advanced ECC techniques, the IO Accelerator can correct up to 11 bits out of every 240 bytes, with a design target of a 1 in 10 to the 20th Power probability of uncorrectable data and a 1 in 10 to the 30th Power probability of undetected bad data. |
