back to article If flash storage achieves FaME, will it live forever?

Data access latency has topped the IT sin charts lately and networked flash arrays have been replacing disk drives, doing away with those drives’ rotational delays. Anything that keeps applications in multi-core virtualised servers running, and not waiting for data while somebody accessing a web commerce page gets impatient and …

    I'm not really seeing the innovation here...

    I'm all for bigger, better, faster and more...but it seems like a really long way to describe the difference between CPU registers, L1, L2, L3, L4 cache, then ram...but instead of then traversing the IO stack to network or SAS or PCIe you just extend the address space to NAND interfaces if available and then go to disk or nas if there is a cache miss.

    Sounds like the OS and hardware vendors should just bake that into the system as a teir, no need to hack or trick anything. The capability didn't exist before, so it wasn't integrated. Now it is, so let's just extend the protocols and standards and keep on trucking...

    WTF?

    What is this, Fox News?

    Author states that internal SSDs are much faster than networked flash arrays. "...A big jump in latency takes us to all-flash networked storage arrays accessed across Ethernet or Fibre Channel, with accesses taking many milliseconds." Who the %#!'s networked flash storage are you talking about? DIMM-type flash arrays like IBM FlashSystem and Violin Memory easily achieve 100-200 microsecond latency - at the host layer - under high workloads. Even the SSD-based "always-on" dedup arrays like Pure Storage and XtremIO can easily achieve 500 microsecond latency under average loads.

    I understand the point of the article is to highlight the speed of putting flash closer to the CPU. Just don't lose your journalistic integrity in the process.

    Next Memristor

    The next thing will be the memristores, nobody writes on them but I believe that end this year 2015, Hewlett Packard began to have the first marketable specimens, with extraordinary speeds.
