1. hardware donation

   Benedikt Grundmann <bgrundmann@janestreet.com> — 2013-07-10T16:53:51Z

   Jane Street has a spare server we would like to donate to the postgres
   community.  We originally planed to use it for one of our database clusters
   and it matches exactly what we use in production at the moment.
   
   Rough specs:
   CPU: 8x Intel(R) Xeon(R) CPU           X5570  @ 2.93GHz
   MEM: 48GB
   
   The server will probably be most interesting for the disks in it.  That is
   where we spend the largest amount of time optimizing (for sequential scan
   speed in particular):
   
   22x600GB disks in a Raid6+0 (Raid0 of 2x 10disk raid 6 arrays) + 2 spare
   disks. Overall size 8.7 TB in that configuration.
   
   Is this something the community would find useful?  If so, who is the right
   person to talk to about shipping/delivery?
   
   Cheers,
   
   Bene

   Mark, we can use this in the performance farm, no?
   
   I know I could use it for testing ...

   Yes, we certainly can.  I can be the contact for shipping/delivery.  Thanks!

   What is the RAID controller used in the server?  That doesn't impact the 
   donation, I'm just trying to fit this one into my goals for finding 
   useful community performance testing equipment.
   
   There are a good number of systems floating around the community with HP 
   controllers--I have even one myself now--but we could use more LSI Logic 
   and Adaptec based systems.

   The server is already turned off and in our nyc office (I'm based in the
   ldn one).  But I'm pretty sure its a LSI MegaRAID SAS 9285.
