Hi.   Not sure if you can use all cores.   It has been and still is my
experience that SM is crap.   We have several SM gpu and SM/Calxeda  Arm
clusters and they really lack in may ways from ipmi to chassis management
to the corners they cut with the processor to memory mappings.

I would consider looking at SGI UV,  ultraviolet system for a fat node type
system but they are not cheap.   We have plenty of those and they can build
it the way you want.   Lead time is a couple of months due to build  to
order.   Support from SM sucks too. :)

We discovered some performance issues with the the SM boards and how they
are layed out.  Granted these were being used  with  HPC clusters in a
fortran development environment used in OG industry.  You probably would
not even notice these running your typical web servers on them.  The ipmi
is pretty annoying and even worse if you get their 10 blade chassis
systems.  Another thing they lack is the error logging abilities and tools
that you get with a fully integrated  system from  say,  ibm, sgi.  Or
other utilities to change bios settings on the fly ..  like IBM Advanced
Settings Utility.  All of these may not matter as much I suppose  with a
small server environment.  You pay what you get for.

Just to clarify:

My use is simply as servers and workstations. Generally I don't use IPMI on
these systems. I have had trouble with the PCIe slots. Specifically, on the
dual core boards some slots are serviced by one set of hardware and other
slots by other sets of hardware. Consequently, if you don't have all cores
populated then corresponding PCIe slots will not work.

Can't say about the four core system, though.

  Is there a faster way to copy files over NFS?
 
  Probably.
 
  Ok, thanks for the specifics.
 
  You're most welcome.
 
  Currently breaking up a simple rsync over 7 or so scripts which
 copies 22 dirs having ~500,000 dirs or files each.
 
  There's a maximum useful concurrency which depends on how many disk
 spindles and what flavor of RAID is in use; exceeding it will result in
 thrashing the disks and heavily reducing throughput due to competing I/O
 requests.  Try measuring aggregate performance when running fewer rsyncs at
 once and see whether it improves.
 
  Its 35 disks broken into 7 striped RaidZ groups with an SLC based ZIL
 and no atime, the server it self has 128GB ECC RAM.  I didn't have time to
 tune or really learn ZFS but at this point its only backing up the data for
 emergency purposes.
 
  OK.  If you've got 7 independent groups and can use separate network
 pipes for each parallel copy, then using 7 simultaneous scripts is likely
 reasonable.
 
  Of course, putting half a million files into a single directory level
 is also a bad idea, even with dirhash support.  You'd do better to break
 them up into subdirs containing fewer than ~10K files apiece.
 
  I can't, thats our job structure obviously developed by scrip kiddies
 and not systems ppl, but I digress.
 
  Identifying something which is broken as designed is still helpful,
 since it indicates what needs to change.
 
  Obviously reading all the meta data is a PITA.
 
  Yes.
 
  Doin 10Gb/jumbos but in this case it don't make much of a hoot of a
 diff.
 
  Yeah, probably not-- you're almost certainly I/O bound, not network
 bound.
 
  Actually it was network bound via 1 rsync process which is why I broke
 up 154 dirs into 7 batches of 22 each.
 
  Oh.  Um, unless you can make more network bandwidth available, you've
 saturated the bottleneck.
  Doing a single copy task is likely to complete faster than splitting up
 the job into subtasks in such a case.

 Well, using iftop, I am now at least able to get ~1Gb with 7 scripts going
 were before it was in the 10Ms with 1.

 Also, physically looking at my ZFS server, it now shows the drives lights
 are blinking faster, like every second.  Were as before it was sort of
 seldom, like every 3 seconds or so.

 I was thinking to perhaps zip dirs up and then xfer the file over but it
 would prolly take as long to zip/unzip.

 This bloody project structure we have is nuts.

I also have a raspberry pi B which I use to stream video and music

OpenBSD-current on soekris 5501 has been running flawless for years too

Lastly I have a beagleboard system which I won that is not doing

There are options out there for sure.  The D525 was under 100 USD ,

  Hello,
 
 
  I am about to start deploying a large system (about 18 To which can grow
 up to 36 To) based on a big Intel platform with lot's of fancy features to
 have turbo boosted platform (ZIL on SSD + system on dongle if I go for
 FreeNAS). Since I want to move on quite fast I might decide to use FreeNAS
 in it's latest version.
 
 
  The idea behind all that was to grant 5 or six critical servers access
 to the NAS so that they can take advantage of :
 
  1. space available on the NAS
 
  2. ability of the NAS to use ZFS and of clients to support this file
 system (including snapshots)
 
  3. Access the server using iSCSI (at least this is what I initially
 planned).
 
  4. Mount part of their filesystem using data stored on the SAN (like
 /usr/local/ or other parts of the system).
 
 
 
  The server accessing the data will be of two types :
 
  1. 2 x Ubuntu server 10.04 LTS
 
  2. 4 x FreeBSD (mainly 8 and 9) with jail configured
 
 
  I have started reading about iSCSI and potential problems with FreeBSD.
 

 What problems do you mean ?



  So my main questions would be :
 
 
  • Should I go for iSCSI ?
 

 Well in all use cases, iscsi should perform faster than NFS.



  • Should I rather choose / prefer NFS ?
 
  • Should I export a Volume as UFS rather than ZFS (is ZFS supported as a
 target) ?
 

 I'm not sure what you mean here, when you export a zvol over ISCSI:
 - your SAN is the target and presents a block device (the zvol)
 - your client is the initiator
 - your client attaches to the ISCSI drive and formats it using filesystem
 XYZ, be it ext3, ufs or ntfs




 
  The main idea is stability, redundancy of data and ease of maintenance
 (in a headless FreeBSD / Linux world) before anything else !
 

 ISCSI is a bit harder to setup IMO, however I think it''s more reliable
 than NFS, what with its auto retries if it loses the network link to a
 device.



 
 
  That's the big pictures, if you have any pointers, advise, they are all
 welcome.
 
 
  It is quite late where I leave, so I will reply to posts in 8 to 10
 hours, but I hope to have enough answer(s) to start an interesting thread
 (as I think this question is very interesting and not so clearly explained
 (at least in my mind))…
 

 This is idd a very interesting topic and I hope to see more :)



 
  Thx very much for your infos and feedback.

Sorrry I do not understand what you mean by try rhtssum,thtssum,momentary
deadlock.

I disabled the onboard ethernet device and installed a new card for the
time being.  Have you submitted PR bug report yet on this?

Intel D525MW board No ethernet devices detected with 9.1 Release

2013-01-05 Thread iamatt
Hello,

I have an intel D525MW board with an ATOM processor.  The system was
running 9.0 RELEASE amd64 with no problems.  I did an binary upgrade
to 9.1 amd64 and now the onboard ethernet card is not detected.  I
encountered a similar issue when I tried to go from 9.0 RELEASE to 9.0
STABLE a while back.

i just flashed the board with latest intel BIOS  but still do not see
the ethernet device.  The  9.0 RELEASE working system  used the re0
driver.  Any suggestions in getting this resolved?


Thanks

Matt
