Software Defined Storage

On Demand Storage

  • Storage is physical, unlike virtual memory and CPU resources there is a persistence requirement.
  • Existing storage or off-the-shelf drives can be used.
  • Groups RAW storage or virtual disks as one iSCSI targets, which makes them more dynamic.
  • In a SAN or NAS a control panel be used to grow or add storage volumes.
  • iSCSI is a network driver with a long unique name and is not vendor specific which would be assigned in a SAN or NAS.
  • In a virtual cloud, on demand storage (SDS) can use any storage hardware.
  • SDS can scale and cross vendors.
  • Hardware can be moved and changed, virtual storage can be moved.

In the Data Closet

Fluke TFS

  • Tests fiber quality, length, and events (reflections, corruption, etc.)
  • Can be used to inspect the fiber for dirt and scrapes.
  • Produces a test light to view pattern.
  • Datacenter mode can test for small distance artifacts.
  • OTDRs can be used to find specific issues and are very costly. But higher quality gear produces accurate locations of problems.
  • Some networkign devices have diagnostic tools built into their transmitter and receivers.
  • With cable crushes, it is not clear when the light source is on or off. These reflections can cause collisions and FCS errors.

Super Computing

  • DoE PS3 cluster (Road runner) is still today #22 of fastest super computers. Has to be retired due to too much power usage. Drastically more power when compared to faster and slower super computers.
  • Moorse Law allows it to be more cost effective to retire old slower and power hungry computers for newer expensive equipment.
  • Distributed (Grid Computing) is inefficient and redundant, thus causing wasted resources. Multiple computers may work on the same data as a fail safe.
  • Super Computers (Homogenous) are central, use similar hardware, and have a central power and cooling source which can be more efficient.
  • Having the power source local, and not converted (From AC to DC for example), there are less power losses.
  • Air condition systems are efficient with hot and cold isles, with a large temperature difference between the two.

Enterprise Bite

Wireless Efficiency

  • Datacenters will get larger and more efficient, wireless requires towers to work.
  • RF Engineers are able to engineer printed circuits with paint.
  • Wireless sites predicted to consume more power and possibly dwarf datacenter power usage.
  • 802.11n uses far less power than 802.11b (10 years prior).
