Alternatives to Dell?

Josh Berkus <josh@agliodbs.com> — 2004-12-01T22:24:12Z

Folks,

A lot of people have been having a devilish time with Dell hardware lately.  
It seems like the quality control just isn't there on the Dell servers.

Thing is, some companies are required to use 1st-tier or at least 2nd-tier 
vendors for hardware; they won't home-build.   For those people, what vendors 
do others on this list recommend?   What have been your good/bad experiences?

Was the quality ever there with Dell?

I use Supermicro and have liked them.  They make motherboards and systems.

My experience with Dell is they are not reliable as well.

Half way between the big guys and home built.  I've had good success 
with Monarch Computers.  They've had ads in Linux Journal for a while 
and a couple of their boxes have been reviewed there. As a matter of 
fact, in the December issue, they did a review of a dual operton from 
Monarch.

  I believe I had expressed some problems with Dell in the past, but
  it really isn't a quality control issue that I have seen.  It is more
  of a Linux support issue.  Lately I've been running into problems with
  getting particular parts of system working under Linux (raid cards, 
  SATA drives, Ethernet cards) or I can get it working, but it
  performs badly ( PERC cards vs say a Mylex card ). 

  I think it's more of a system design issue ( wrt Linux use ) rather
  than a quality issue.

Which is a shame, because I *still* drool over a rack full of those
front bevels with the bright blue LEDs. :)

I'm using an HP DL585 quad Opteron with 16G RAM as a development box. 
It's working great. ;)

Seriously though, I never really liked HP (or worse, Compaq) hardware
before, but this box seems really well built, and I've yet to see a
'D' in the S column in top with the SA-6404/256 RAID card.

If all goes as well as it has so far on this testbed I'll be deploying
on a Slony-1 clustered set of 3 of these bad boys with 32G RAM each. 
Dollar-for-dollar, we're saving 90% (that's right, an order of
magnitude) going this route, PG with linux-amd64 on HP/Opterons, as
opposed to the E20K monster that was originally spec'd out.

Mail me direct if you want the full spec list on this beast.  And if
there is a ready-made benchmark anyone would like me to run, just drop
me a note.

Well this is almost as bad as vi/emacs ;) but I have had good experience 
with Compaq Proliant (now HP) servers. I have also "heard" good things 
about IBM.

IBM actually sells a reasonable costing Opteron server as well.

The problems I've been dealing with have been on the *650s.   They're the ones 
you name.

I don't know if Vivek is on this list; I think he just had a critical failure 
with one of the new Dells with LSI.

I recommend IBM equipment, but in the spirit of caveat emptor  I should let
you know I work for IBM... :-)

Seriously, I've been using IBM laptops and desktops for about 5 years, even
before I started working for them.  They tend to be a little more expensive
than Dell, but I think they use beefier components and don't cut the specs
quite as close as Dell does.  IBM gear is designed more for industrial use
than home computing, which is reflected in the quality (and the price).

IBM just released a new series of PowerPC-based servers that are
specifically designed to run Linux.  They're at the higher end, but from
what I understand, they provide much more bang for the buck than
Intel-based servers.

I hope this helps,

On this note about "Adaptec junk", I have a question regarding hardware 
as well. We tend to build a lot of servers in house (Supermicro based 
with the Zero-channel raid). Does anyone have any anecdotal or empirical 
data on using a ZCR card versus a full-blown RAID controller (adaptec or 
other)?? I am trying to build a medium-duty database server with 8G RAM, 
4x144GB U320 Scsi RAID 10, FreeBSD (5.3-stable or 4-stable) and was 
wondering about performance differences between ZCR and Adaptec versus 
other manufacturers' Full-RAID cards. (PCI-E)

We use a bunch of HP ProLiant DL360 and DL380 without any problems at

Many of their rack-based servers seem to be near-impossible to fit in a rack,
though. :-) (Many of their 4U servers are just desktop cases which you can
turn on their sides and apply an extra kit onto, and into the rack it goes...
after a lot of pain. :-) )

I've had very good experiences with IBM hardware, and found their sales

Consider Sun's new line of Opterons. They've been around for a couple of
years under the Newisys name. I'm using dozens of them for web servers
and PG servers and so far both the v20z and v40z have been excellent
performers with solid reliability.  The pricing was also competitive
since Sun is looking to break into the market.

Most of mine I got through a Sun reseller. Some of mine I got off of
Ebay.  You should be able to get them a lot cheaper than than retail web
pricing. :)

However, even full retail seems like it was a hell of a lot cheaper for
a v40z than a DL585. :)

That's true :) One of the reasons the compaq's are expensive
is they supposedly use a quad board, even for the dual machine.
Which means a different opteron chip as well.

I don't know this for a fact, it is just what one of their
"ahem" sales guys told me.

The IBM machines are seem reasonable though.

We were originally heading towards an IBM deployment, but the 325 was
all that was available at the time, and it only supported 12GB.  Then
when I heard they canceled their rumored quad processor 350, I feared
Intel/AMD politics and IBM dropped from the running. :)

(IBM now has the 326 that supports 16GB of RAM)

I can confirm that.  You have a choice of CPUs, but all the DL585s are
expandable to 4 procs if you get the 800 series Opterons.  Each CPU
sits on it's own daughter board that links up the HyperTransport
busses between all the others.  Each CPU card has (I think...) 8 slots
for DIMMS, for a max of 64G.

At least in that case they were being accurate. ;)

Why would I want that giant beast when a 1U will do for dual
opterons? :)

The V40zs have dual procs on the main board with a daughter board for
the other two procs. Each CPU has 4 DIMM slots. Sun has the daughter
boards for an outrageous price, but you can buy white box Newisys
daughter boards for a lot less.

The 64GB of 2GB DIMMs I am jealous of, other than that, the DL585 is so
outrageously priced I never considered it.

I wouldn't buy a ray of sunshine from Sun in the middle of January at
the north pole, given the customer experience I had with them.  They
had consistent failures in some critical hardware, and it was like
asking them to donate a kidney when we tried to get the things fixed. 
Finally, they told us that they'd sell us the new line of hardware
instead.  In other words, "The last version was broken, but _this_
one works!  We promise!"  We told them to take a long walk off a
short pier.  Their service people sure _try_ hard in the field, but
some machines required three and four visits to fix.  

I also find the Sun Opteron offering to be way overpriced compared to
the competition.

In case it's not obvious, I don't speak for my employer.

Drivers for their devices are not problems, but performance is.

Their RAID cards are either Adaptec or LSI, but people who use the
"real" branded versions of those cards always seem to get better
performance.  Way better.

I'm considering FreeBSD systems and a custom built configuration right
now.  Very hard decision to make.

For desktops and web/office servers, I still like the Dells.  Just not
for the DB servers anymore.

I'm here, but time delayed :-)

No critical failures on the Dell, just performance failure.  It can't
keep up.  You'd think with a box like this:

4GB RAM
Dual Xeon (32 bit)
PERC3 (LSI based controller) dual channel
chan0: RAID1 two disks for OS + pg_xlog
chan1: RAID5 14 disks U320 18Gb
FreeBSD 4.10
PG 7.4.6

I should get better than a sustained 6MB/s I/O throughput with peaks
to 30MB/s and about 30% the tracks/sec others report with name-brand
LSI controllers with Opteron systems.

The computer is wicked fast, but the I/O can't hold up, and I can't
get a straight answer as to why.

I'm no closer to solving the vendor problem than anyone else here.

Way off topic, but Dell regularly advertises included hardware that is
"almost" the same as the name brand hardware if purchased individually.

My brother bought a Dell and needed to upgrade his video driver and the
Dell tech said he has to use Dell's drivers rather than the
manufacturers driver because the video card isn't identical to the
manufacturers.  Of course the manufacturer had an updated driver that
fixed the problem while Dell had only the broken one.  He upgraded the
driver anyway and it worked.

Do you want to purchase hardware from a vendor that tries to shave every
dollar off the hardware cost, even if compatibility or performance
suffers?  I don't.
