Source For Fans For Supermicro SC833's
Aug 7, 2009
We have a large number of the 2U SC832 and SC833 cases from Supermicro that have been real workhorses over the years and some have had various motherboards in them as time went by. All of them are 5-7 years old and we would like to keep using them, but are concerned about the fans in the power supplies getting worn out and failing. Anyone have the source for good high quality fans that would work in these 400 and 550 watt single power supplies?
Anyone have an idea of what the normal life of one of these power fans is? All of them have been in good datacenters from there first use.
Since I know there are a lot of Supermicro users on this forum I figured this would be the best place to ask.

Any recommendations for 2u e55xx lga 1366 cpu fans? We recently put together a few systems with passive supermicro heatsinks on those cpu's and they keep overheating. I can't seem to find any decent 2u active fan solutions? What is everyone else using?

Got a question about cases fans but know someone will have a laugh at me about this.
We have recently moved from 1u supermicro cases to matx cases to lower the general server cost. We realised that we wouldnt fill 2/3 of a rack if we used 1u (16 amps power would be hit) and it was just logical to use matx.
One worry is the heat factor so was looking at some powerful fans. The one place I know where to get them from is our dyanatron supplier but I am left very confused. You always see on fans they use 0.3amp/12v (for example) but how much does that work out to be at the final power usage? this goes for the same in watts. Are fans something you have to worry about in the long run or do they make a non exsiting dent into a racks amp usage?

I have a 6RU rackmount server cabinet, which I am putting a 1RU server inside.
I am wanting to put some fans in the metal cabinet, to bring in cool air, and let out warm air.
Does anyone know where you can find these sorts of fans?
Because the server inside the rack cabinet is closed, I can't use a fan with a Molex connector.
I haven't seen any case fans that use a usb connector, or just a normal power outlet connector.

I'm under the gun, and looking for a source for 40km and 80km XFPs (e.g. Finisar, Agilestar), who keeps them in stock and at a good price. I prefer to work with vendors who are subject to US law.

I bought two Dell R200 because they was extremely cheap.
My target is Open Source SAN with active/passive setup.
Now i was wondering what RAID-level I should go for.
I will use 1TB SATA-II disks.
1) RAID-1 in both servers and mirror each other with DRBD.
With this setup i have like double RAID-1 so i lose lots of disk space.
4 disks -> 1TB
2) No-raid at all and i will mirror data with DRBD.
4 disks -> 2TB
Then there is change to go for RAID-5. Theres enough space to put third disk in that case
3) RAID-5 in both servers. Mirrors data with DRBD.
6 disks -> 2TB but more performance.
But in every setup i lose space more then i would like to.
Actually i dont need space more then 1TB, but i would like to get best possible redundancy and most space available i could.
Also need to remember that those servers does not support hot-plug HDs so in case there is disk-failure i need to be able to shutdown one server and iSCSI should still be up and running.
Of course theres change to make it active/active.
I was thinking that if I go for the RAID-5 I will make LVM-VG on both nodes (san-vg1 and san-vg2) and use it 50/50.
In case of fail both VG's will be used from working node.
Im going to use Debian Lenny I guess..
I was looking for OpenFiler because of the GUI, but im familiar with Debian and have always done everything from cmd.

Running ubuntu server 6 if I apt-get php5 the version I get is 5.1.2.
Now the latest version on the php.net site is 5.2.5.
Does it really make much of a difference if I'm slightly below current? What are your thoughts please?
I know if I go compiling from source php and mysql are difficult to get working together which is why I like the apt-get method.

Which PHP encoder do you all suggest out of Ioncube and Source Guardian? Or possibly another if you know a good one. I checked out Zend Encoder, but its expensive as hell.
Currently I'm thinking about Ioncube. I know the majority of web hosts have ioncube loader installed, but I'm not sure about source guardian.

when I compile lighttpd from source -- I cannot seem to enable/disable the modules I need.
I have tried
./configure --without-status --with-rewrite
and also
./configure --disable-status --enable-rewrite
but no luck. The rewrite flag may not work since the configure script may or may not detect the pcre library, but status should be disabled.
After the configure script is complete, I get a listing of the enabled/disabled modules that are in the build and nothing new has been changed.

if a program is compiled and installed (configure -> make -> make install) with a --prefix pointing to an empty subfolder, then would removing it be just a simple delete the folder and it's contents action ($rm -fr subfolder/).
Ok so lets say I was to install php from source with a complile prefix flag set to /usr/local/php
Then all the binaries and configuration files are set within the directory (php/conf , php/bin). If I want to delete the php installation then I would just remove the /usr/local/php directory, No?

Thinking very seriously about revolutionizing the ISP market, starting with WiMax-based service in the Texas hill country, as I'm tired of the basic monopoly outside of town and the near-monopoly in town for halfway decent access. Anyhow, I plan to get Cogent FastE for the main backbone, however I know I need something else in case some spat starts between Cogent and someone else (Level3, France Telecom, Telia). Internap is in Austin I know, but Cogent has a POP in San Antonio which is much closer to where I'm going to deploy the network. Any options in the Internap price range for maybe 20 Mbit to start? Yeah, I know that the price of the "backup" connection may be more than that of the main line, but if people want their WoWwebetc. I want to live up to that promise.
Thanks in advance. If I gotta use Internap I'll do that, but again that means setting up a link in the opposite direction to what I'm thinking right now. The ultimate answer would be something relatively inexpensive (sub-$100 per Mbit with 20 Mbit commit) relatively close to one of Cogent's San Antonio data centers. Cogen't bandwidth deals are awesome, but with one peering argument per year or so a backup seems needed.

I have been getting multiple emails a month for a service which I have never purchased.
The information they have harvested off the internet (since I know where they found it) and have obtained solely for use in attempting to charge me is-
Invoiced To
Steven Crothers
12345 Main St.,
Detroit, MI, 48021
United States
Which is completely obvious that it is fake.
I respond to EVERY invoice with a cancelation request, yet the tickets that get opened in the WHMCS billing panel get deleted a day later, however I have tickets in there that I have opened by use of the ticket insertion form that have stayed - none of which were ever answered.
The latest ticket information-
Department:Billing And Invoicing
Date:09/10/2009 10:05
Subject:The Second Time...
Status:Open
Urgency:Medium
It's still open without a reply.
I have put tickets into their Kayako system as well (They have two support systems, I would assume its due to poor management of their company). One of which was answered, with simply the output of `uname -a` on some server somewhere with my name as the hostname.
I than have attempted to reach anyone via livechat at [url]they constantly tell me that I am not allowed to speak to anyone until I pay my bills up to current (now remember, I have NEVER ordered anything from them, they don't even have valid information on file). Just tonight I demanded that I required to speak to a billing agent or I would be pressing harrasment charges against them for the 23 emails I have recieved in 3 months from them trying to extort money from me. They than banned me from their LiveChat software.
I have no idea what to do at this point, they are just sending me bills every month. I mark it as spam, but its frustrating to have a company trying to extort money from me on a very regular basis.

how many players you would estimate the following server could handle running Counter-Strike Source dedicated Server?
Dell PowerEdge 1550 1U Rackmount Server
1Ghz P3 Processor -
1GB RAM
2X36Gb U160 SCSI Hard Drives in RAID1 for redundancy
Windows 2000 server
Network connectivity is 100mbit in a London DC.
Of course its not possible to give a 100% accurate figure however i would like a rough estimate prior to me purchasing this machine.

I have many years of experience with Intel (SR1325, SR2200, SR2300, etc) and HP ProLiant DL servers, and have come to love HP. Their ILO2 remote management/power/KVM/VirtualMedia feature is hands-down the best I've used, and for me it's been 100% rock-solid reliable (unlike the horror stories heard about Dell DRAC cards flaking out and locking up when you need them most).
Now there's something shiny catching my eye-- the Supermicro 1U Twin systems.
http://www.supermicro.com/products/nfo/1UTwin.cfm?pg=1
Given my long positive history with HP, I'm reluctant to consider another brand, but it is hard to ignore double-density servers with colo prices (rackspace costs, not just power costs) spiraling upward.
I would love to hear from folks who have used both HP and Supermicro boxes in production. Specifically, about reliablity of the Supermicro platform in general AND about the reliability of their IPMI management modules even under Murphy's Law situations. The last thing I need is not to be able to remote-console or power cycle an unresponsive server because the IPMI card is flaky.

I know this topic has been brought up before and I wanted to revisit this again. We are a growing hosting company looking to expand our Dedicated server offerings. So far, we have been renting servers and reselling but now we have begun colocating our equipment and are looking for hardware vendors.
Would you recommend us to...
...build our own servers using the Supermicro platform?
...purchase pre-built servers from Dell?
...purchase pre-build servers from HP?
Pricing is of major concern along with speed to provision new orders. Although we don't have a dedicated resource for putting together servers, this is something we can look into should the volume of orders increase. Scalability and Flexibility is a MUST
Thanks for chiming in...
