[Gluster-users] working inifiniband HW ??

2013-07-08 Thread HL

Dear List,

I am currently testing glusterfs on a small scale  non-production env 
with ordinary nics.


I would like to purchase a couple of inifiniband nics in order to 
connect 3 servers in point to point mode

that is with no switches in between.

Since I've noticed that some of you have this kind of H/W
Any info on brands/models and
a good known to work setup
will be highly appreciated.

Regards,
Harry

Depends on the kind of performance you're after. :)

If you're just wanting something better than 10GbE at minimal cost,
these work fine under Linux:

  http://www.ebay.co.uk/itm/360657396651
  ~US$40 each, not counting postage

They're rebadged Mellanox MHGH28-XTC cards.  Completely ok to be
flashed with standard Mellanox firmware.

For cables, I use these:

  http://www.ebay.co.uk/itm/251200441924
  US$14 each, not counting postage

Note, I'm comfortable getting stuff off eBay where the seller
seems ok.  So far, so good. ;)

If you do decide to use the above stuff, and later on want a switch,
try and find a Voltaire ISR 9024D-M.  They're DDR infiniband (20Gb/s
per port), and can run fanless (completely silent).

  http://www.ebay.co.uk/itm/350827346490

They can be had pretty cheaply if you're willing to wait for good
pricing.  I got mine for ~US$270.

Hope that helps. :)

Regards and best wishes,

Justin Clift

I concur - I used the same cards on our test cluster - just make sure you
upgrade the firmware  to the latest revision:
http://www.mellanox.com/content/pages.php?pg=custom_firmware_table

The fw upgrade is not trivial - well, it IS trivial, but bringing all the
info together was not - if you want some rough notes, let me know.

Nowdays there should be copious info on the new Mellanox Community
website (recently launched):

  http://community.mellanox.com

Saying that because I've written out the step-by-step instructions
for people on the forums there a bunch of times over the last
month or two.  :)

Searching for flint or mstflint should pull up appropriate
stuff for anyone else who needs it.  Hopefully useful. :)
