A New level of Solid state storage is now available for customers who needs the ultimate in I/O Read and Write speed performance...and in my opinion ultimately the way forward for server storage in the future..
Firstly before we get into the speeds and feeds...
What is an I/O accelerator? - An I/O 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.
Just how fast is this storage?? well see for yourself....
600278-B21 - HP 160GB SLC PCIe ioDrive- Usable Capacity - 160GB
- Technology - NAND Flash, SLC
- Bandwidth - 670 MB/s Writes, 750MB/s Reads
- Latency - 50 microseconds
- IOPS - 93,000 IOPS (75/25 R/W mix 4K packet size)
600279-B21 - HP 320GB MLC PCIe ioDrive- Usable Capacity - 320GB
- Technology - NAND Flash, MLC
- Bandwidth - 490MB/s Writes , 700MB/s Reads
- Latency - 80 microseconds
- IOPS - 67000 IOPS (75/25 R/W mix 4K packet size)
600281-B21 - HP 320GB SLC PCIe ioDrive Duo- Usable Capacity - 320 GB
- Technology- NAND Flash, SLC
- Bandwidth- 1.4GB/s Writes, 1.5GB/s Reads... !!!
- Latency - 50 microseconds
- IOPS - Over 125,000 (75/25 R/W mix 4K packet size).
600282-B21 - HP 640GB MLC PCIe ioDrive Duo- Usable Capacity - 640GB
- Technology - NAND Flash, MLC
- Bandwidth - 1.0GB/s Writes, 1.4GB/s Reads
- Latency - 80 microseconds
- IOPS - Over 120, 000 IOPS (75/25 R/W mix 4K packet size)
As you can see there are huge performance gains on storage speeds. Now as for price... well we will skip that for now as you can imagine they are pretty expensive, sometimes needs must though !!
I also hear you ask what is NAND MLC and SLC and what is the difference? Well NAND is a technology that uses flash memory cells to store data. Single level Cell (SLC) stores one bit (data) 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 (Slower) than SLC.
These cards cannot be used as a boot device as yet, also these cards are only supported on the following operating systems at this time, RHEL 4,5 (64-bit support only); SLES 10, 11* (64-bit support only), Windows Server x86-64 2003, 2008 (64-bit support only).
