  • One of my colleagues showed me dstat, a very nice tool for system monitoring, and bandwidth of a drive monitoring. Also ifstat, as complement to iftop is very cool for Network too. This functionality is also available in CTOP.py
  • As I shared in the past news of the blog, I’m resuming my contributions to ZFS Community.

Long time ago I created some ZFS tools that I want to share soon as Open Source.

I equipped myself with the proper Hardware to test on SAS and SATA:

  • 12G Internal PCI-E SAS/SATA HBA RAID Controller Card, Broadcom’s SAS 3008, compatible for SAS 9300-8I.
    This is just an HDA (Host Data Adapter), it doesn’t support RAID. Only connects up to 8 drives or 1024 through expander, to my computer.
    It has a bandwidth of 9,600 MB/s which guarantees me that I’ll be able to add 12 SAS SSD Enterprise grade at almost the max speed of the drives. Those drives perform at 900 MB/s so if I’m using all of them at the same time, like if I have a pool of 8 + 3 and I rebuild a broken drive or I just push Data, I would be using 12×900 = 10,800 MB/s. Close. Fair enough.
  • VANDESAIL Mini-SAS Cables, 1m Internal Mini-SAS to 4x SAS SATA Forward Breakout Cable Hard Drive Data Transfer Cable (SAS Cable).
  • SilverStone SST-FS212B – Aluminium Trayless Hot Swap Mobile Rack Backplane / Internal Hard Drive Enclosure for 12x 2.5 Inch SAS/SATA HDD or SSD, fit in any 3x 5.25 Inch Drive Bay, with Fan and Lock, black
  • Terminator is here.
    I ordered this T-800 head a while ago and finally arrived.

Finally I will have my empty USB keys located and protected. ;)

Remember to be always nice to robots. :)
