No more bottlenecks: Accelerating real-time data access in blades the solid state way

By Tim Ellerbe, Product Manager


Wouldn't it be nice if we could eliminate applications and database performance problems by running them 100% in DRAM? RAM's nanosecond latency makes it ideal as a temporary workspace for operating systems and applications. However, its volatility makes it unsuitable for applications that need to persist data. It's also difficult and expensive to cram enough DRAM into a server. Additionally, its expense makes it impractical to purchase the capacities most applications need. 


Consider this...


The HP StorageWorks IO Accelerator brings high I/O performance and low latency access to storage, with the reliability of solid state. It's a mezzanine card for HP StorageWorks BladeSystem c-Class servers (and soon to be released PCIe version for selected ProLiant DL/ML servers) that provides the performance boost that IO-starved applications need without sacrificing reliability. These NAND Flash-based cards add terabytes of DRAM-like acceleration to blades in a new persistent memory tier with advanced error checking, self-healing and RAID5-like redundancy.


But isn't a persistent and reliable memory tier with RAM-like speed even more expensive than RAM? The IO Accelerator costs roughly $48/GB.  Compared to DRAM (roughly $125/GB MSRP), it's a bargain.


The benefits added up for one BladeSystem customer who added IO Accelerators to its MySQL database clusters to get the following benefits:



  • 30x faster database replication-during testing, a new read database caught up to the master in 12-1/2 minutes compared to 6-1/2 hours for a standard serve

  • 6x faster complex query processing, from 2700/sec to 350/sec per blade

  • 30% faster query response times

  • 8x faster worst-case disaster recovery

how does that compare with TMS RAMSAN-20 ?

No it probably does not compare to an ensire disk array comprised of SSD. But many applications and environments don't require that kind of IO for all their applications, or require so much SSD for primary storage space. The ability to have a device to cache enough data so as not to saturate standard disk IO capabilities is what these devices are used for.. not a sustainable SSD disk tier like a RAMSAN

Hey Calvin,

What percentage of bottlenecks out there have a root cause of I/O performance or latency?  What about poor coding practices or architecture?

Cheers,

I contacted HP customer service in 01-09 because my wireless stopped working on my dv6000 and was told that I was 2 months out of warranty.  So I bought a wireless adapter and used it until last week win my laptop will only turn on after trying several time with the on/off button (motherboard defect).  I contacted customer support and  spoke with someone based in the Phillipeans, he spoke excellent English and pass me on to a case manager.  The case me passed me on to a higher level case manager named Jason.  Jason passed it up to a higher level and they refused to fix my computer.  I have a copy of a letter I received from customer support back in 01-09 when I called about the broken wireless.  This is should serve as proof that that I reported the problem and was not told about the extended warranty at that time.

I would like someone to contact me concerning this issue
