That's my understanding as well, and one of the reasons I picked up the SSDs listed in the first post.
Performance is currently on the poor-ish side on my new array, but substantially better then what were were getting on the old array, and even that was an improvement over XFS crashing on a...
I've noticed that dedup puts a lot of load on the system during my testing, and you guys are not the firsts to advise staying away from it until it matures.
There are plans to get the server to 32+ GB of ram, and when dedup stabilizes, I'd love to use it for our VM level backups...
Yeah, I know about this. Was not my call and let's just say I had other battles to win that week.
Aaaannyway, the new zfs array is setup correctly, with the disks in JBOD mode
The testing for RaidZ showed the best Write/Rewrite speeds (not accounting for CPU usage) were with dd=0 (dedup)...
So a while back I started a project to migrate way from XFS to ZFS on our backup server [Link here]
The machine specs are now
2 x Xeon 2.26Ghz
2 x 80 GB WD
2 x Corsair Corsair_Force_3 120GB
8 x 2 TB Western Digital WD2002FYPS SATA 5400RPM
8 x 2 TB Western Digital...
So I inherited our backup server, and been tasked with rebuilding it. From a hardware point of view it consists of
2 x Xeon 2.26Ghz
2 x 80 GB WD
8 x 2 TB Western Digital WD2002FYPS SATA
1 x 3ware 9650SE-16ML 16 Port SATA Raid
When I first got the machine...
I do agree that Untangle is not to expensive, but it is more expensive then our current solution (0.00$).
I've already tried to make the case for the increase in spending, to which I was told the reason to bring in the anti-spam is that we're going to cancel our contract with our current...
I'm starting work on a new project - to remove the old linux based iptables firewalls from the office and implement a dual redundant firewall with failover. A side project is to also have some sort of web content protection and SMTP anti-spam/anti-virus in house.
I have an SSG20 at home and love it. I converted from linksys (and DD-WRT/Tomato) -> Cisco -> Smoothwall -> Juniper
and I'm sticking with Juniper.
The screenOS is used on the SSG line. Junos on the SRX.
Yeah, that's the issue I'm having. Is there a seperate application/service for each of the events (Fileshare vs logon) that I can use to build a policy around on the firewall? If they are both ntoskrnl.exe then I'm hosed eh?
The DC is the file server... sigh
The issue is that when I block outbound TCP 139 and 445 and UDP 137 and 138, the server returns a message when I try to logon with a new account
"The system cannot log uoi on due to the following error:
The RPC server is unavailable
Please try again or consult your system...
I'm trying to build a firewall policy that will do the following on a Windows 2003 Server
From the 2003 Server, allow it to contact the DC to process logons
Not allong the same server to browse the network. IE: no outbound connections
I'm having issues with the Windows TCP and UDP Ports...
I found that using any form of torrents would hammer my gaming speeds (re dropped packets, ping, etc)
I got myself a used Juniper SSG20 (http://www.juniper.net/us/en/products-services/security/ssg-series/ssg20/) and after building a few rules to prioritize my Steam and HTTP/HTTPS/DNS/ICMP...
I work for a company who are going to be splitting our office into two seperate companies and will need to split the one network as well with a shared DMZ for the equipment that belongs to both companies. The problem we have is with our ISP/consultants.

I hate bumping a semi-dead thread, but on the other hand I hate finding threads that leave you without a conclusion.
I've finally fixed the stability issues with the mobo. Turns out that it was due to the USB flash drive I was using to boot off of. I tested 2 other flash drives from OCZ and...
Quick question that I didn't know where else to put it;
Does anyone here have a copy of the Robert Half 2009 IT Salary Guide? I saw it was posted last week, I requested my copy, but they are slow to respond. I wouldn't normally ask, but I need it for Monday... ???
Thanks for all the feedback everyone.
I found a Adaptec Support Knowledgebase article that lists a known issue with the 5808 card and some drives that causes a lockup, so I'll be upping the firmware and reporting back later as this will take some time todo.
Known Issues with Seagate...
I think I'm starting to have disk I/O troubles. Every now and then all the VM lockup (screen still displays, but nothing's going on) and on the performance log of the ESX console everything flat lines.
Looking at the case, i see all the drives access LEDs' lit but nothing going on... Not...
Tell me about it. I'm installing my guest OS's on the server and it's flying. Granted that Im installing off and ISO image I made.
Question: I'm not able to give all my space to VFS in ESXi. I can see all the space, but I can only make a VFS out of 598.99GB of it...
Does it have anything to...
Updates with Pics!
So parts have started to arrive, I'm still missing the RAM, Heatsinks, CD drive, and 4 of the drives (I order my drives from different suppliers at different times to minimize getting a bad "batch" of drives)
Anyway everyone's here for pics!
Box shots! Hey wait! is...
I've been doing some more reading, and planning and have decided to change a few things around from my initial build.
I would like to take back my statement that ESX is all about tradeoffs. That's not quite what I meant. Doing ESX on the cheap is about tradeoffs in regards to when you will...
I was thinking the RAID 0+1 option, but I don't like the drop in disk space. Now, adding a 7th and 8th drive will give me 4TB before funky counting dwindles that down to ~3.6TB, but that will fill up my Storage controller, and leave me with no room to grow, which is the problem I am facing now...
So it looks like there is no way around the storage server. hmm.. that means that I'll need 2 more small disks for the ESXi box and a new case for it. The Adaptec card will go into that PE830 as I lucked out and it has a PCIe 8x slot, and I'll probably need a new NIC for it too and a touch more...
It's been a while since I've had a big project to document and seeing this new Virtualized Computing section made me feel like starting a new log

IBM uses a hardware device called an RSA (Remote Slimline Adapter.) You'll see that the is an extra RJ45 port on the back of the server where you can plug in a network cable and have console access to the machine from anywhere with an IP
A few weeks ago we moved the share that holds user's my doc's from one server to another. On the old server offline files were setup to replicate the files down to the computer. When we moved to the new server, the same was setup. Now about 1 in 50 users still see the status of the...
This would be for 50-75 users. The Barracuda 300 is a nice unit giving us the ability to move past our current user base, and also allow us to add more domains without having to license for more users (the owners love opening other companies and have 1 person do the same job for 3 companies...
