Re: 32Gb servers?

[Mike Tewner]

Have you looked into using memcached ?

http://www.danga.com/memcached/ :

memcached is a high-performance, distributed memory object caching system,
generic in nature, but intended for use in speeding up dynamic web
applications by alleviating database load.

Danga Interactive http://www.danga.com/ developed memcached to enhance the
speed of LiveJournal.com http://www.livejournal.com/, a site which was
already doing 20 million+ dynamic page views per day for 1 million users
with a bunch of webservers and a bunch of database servers.
memcacheddropped the database load to almost nothing, yielding faster
page load times
for users, better resource utilization, and faster access to the databases
on a memcache miss.

Amos, what is your budget for this ?

There are a few options:

SGI 1200 or SGI 2100
HP DL360G5
Dell PowerEdge 1950
IBM x3455
IBM x3550
No name Intel based boards stuff (if you're talking about
5 exits, try Data-Store - they are one and the same AFAIK
- www.datastore.co.il)

However, for a server with 32GB memory, I would go
for one of the brand names.

 Hello,

 Where would you go if you had to get a 32Gb RAM server, much
 preferably rack-mounted.
 Don't care so much about CPU or very fast disks, just needs lots of RAM.
 Can run either Windows (possibly developer's preference) or Linux (my
 preference).

 Dell's smallest server which supports 32Gb jumps the price to over 45k
 when it comes with 32Gb, 44k of this is just for the ram.

 I'm trying to dig the other big name brands (IBM, Sun, SGI, HP) but so
 far their web sites weren't very helpful to understand what can they
 offer that answers these simple requirements.

 Thanks,

 --Amos

 Your suggestion about pinging with different sized packets showed me that I 
 couldn't ping with more than 512 bytes. I set the mtu to 512 and can now send

 1 - the internet is VERY slow

512 is really low - analog modem style low, and not even modern v.90
modems, but old v.42 modems (which used 768 bytes IIRC). This accounts
for the very slow speed, but it also indicates a very serious problem.
But 512 is too a nice a number to be attributed to line noise, I think.
I would suspect something wacky going on with hardware somewhere -
either your DSL modem or the Bezeq DSLAM.

 2 - Although I can work, none of the other machines on my network (Linux or 
 Windows) can do anything on the Internet. 

You need to make sure that none of the other machines use MTU larger
then 512. Its easy to do automatically by adding a clamp MSS entry to
your iptables masquerading setup: STFW for clamp-mss-to-pmtu.
