    BIG tower vs MIDI tower

    Damn, even THG is calling them midi towers! THG case review Yes MIDI has NOTHING to do with size of a damn computer case. I have a MIDI keyboard and it still has 88 damn keys. Cheers!

    Samsung 243t

    This is a good idea however the only card that's reasonably priced (GF 6800U DDL-DVI) is MAC ONLY! Quadro 2000FX and higher will drive it natively, but they are too expensive. The 23" model is a good option, however and cheaper than the 243T. Cheers!

    Samsung 243t

    I would avoid the (243T) if you plan to use DVI. This display has serious video dynamic range issues that are not present when using analogue input. Like anyone is going to spend $2k to use analogue input! When an image dims down (fade to black) serious artifacts occur. This does not show up on my 213T nor my Sharp WUXGA display on my notebook. I've tried several different cables, display adapters, etc. with the same result. I've also tried several samples of 243T product and they exhibit this same behaviour. The easiest way to see this is run the 3DMark03 program and watch the beginning of the Troll Slayer section that starts dark and fades up. You will see this horrible artifcating. It's not video card related or software related whatsoever. This is also present in movies as well as images when edited in PS. This is totally unacceptable for a display of this calibre and I am sending all of mine back for a refund. Cheers!

    6 X 15.3k In Raid 5

    128KB works best with SRCU42X. Also, those reads should be in the 450 range. Is the HBA running at 133MHz PCI-X? Cheers!

    Lsi Logic Megaraid 320-2x Pci-x Scsi Raid

    Crucial works fine with no problems. Module is single sided too! This was installed on the Intel SRCU42X which is identical to the 320-2x. (LSi makes the part for them) Cheers!

    Lsi Logic Megaraid 320-2x Pci-x Scsi Raid

    Very good choice in configuration. I see no problems at all with this setup. Purchase the battery backup module for your 320-2X and run all logical drives with write back cache. You will also achieve great gains by upgrading the standard 128MB DDR DIMM to 512MB in this card as well. Crucial Part number CT6472Z335 Details Cheers!

    Pci-x Cards...

    Edirol FA-101 Cheers!

    Pci-x Cards...

    This will fill the bill nicely. Just add a PCI firewire card and you're all set. Cheers!

    Raptors 74gb In Raid 0

    STR isn't everything! (Eugene needs a beating a dead horse icon!) I've benched and used the Raptors and they are quick. Still, high end SCSI is even faster. If you look at the bench below you would think otherwise. I'm using the machine that produced those results and can say going from two raptors in RAID0 to that system (the benchmark is actually 4 MAS 15K drives in RAID10 on LSi Logic U320-2X w/256MB) is like going from a 400BB to a pair of Raptors in RAID0. The HD Tach results are laughable as the true burst is over 800 MB/S and STR on the RAID10 logical disk starts at 170MB/S and ends at 145. Cheers!

    Raid 1 Or 10 ? Much Improvement?

    What OS is the server running? If Win2k or 2k03 is it an Active Directory Controller? Cheers!

    For All The Abit Haters

    Oops, no edit... Anyways, that would be FOUR years ago... I bought those boards in January of 2000. Time flies when you're busy. I remember installing Windows 2000 final on those systems. Cheers!

    For All The Abit Haters

    Hell yes! It was the P3C2000 using the i820 MTH (SDRAM). Such a silly arrangement that was. Never got compensated either. If that wasn't enough, I got burned yet again with a P4S8X. Asus has been crossed off the list. SuperMicro makes a great workstation board. Cheers!

    Hdd Speed Comparison Stuff

    The most important thing has not been addressed yet! The HBA itself. Those DPT HBA's were very slow in RAID0. Like the Adaptec 2100, RAID0 should be called JBOD with stripes. Those old SCSI disks will be hot, noisy, and slow on a desktop. That HBA is ultra2 not ultra 160. Either way the peak STR will not come close to approaching 80MB/S let alone 160 if that were possible. A fast HBA makes all the difference in the world but you (generally) do get what you pay for... Cheers!

    Server Setup On A Raptor

    If you MUST use the config mentioned above, add as much RAM as possible and make sure it is ECC memory. A good UPS is also a MUST as well. For Exchange (especially with 50+ users!) we like to use mirrored SCSI OS and separate (mirrored or even RAID 10) disks for log and database files. A hot spare for EACH member is also a requirement for best availability. Yes it can get expensive but do you really want angry users breathing down your neck while you try to get an Exchange box back up? Never mind when you have to run eseutil and isinteg to repair your database after it gets corrupted from doggy (non server) hardware. (cough}highpoint controllers(cough). What version Exchange? That 16GB limit will come fast with 50 users with the non enterprise version so you better have a strict archive policy in affect. I'm sure the real Exchange Admins (Honold?) can discuss this in more detail... Cheers!
  15. While there are no empirical statistics showing the correlation between drive handling characteristics between the supplier and the end user, I believe a relationship does exist. Thus if your drives are mishandled, the chances of an anomaly surfacing that threatens the integrity of stored data and/or physical reliability is much greater than if the drive is properly handled. I've dealt with HyperMicro and Googlegear and they (both) use good drive packing/handling practice. Computer Giants used to pack well, now it appears that they just throw the drives in a box of foam shavings! Cheers!

    Disk Queue Length On Large Servers

    Your Data, your Servers (or even both!) are FOO+BAR=FUBAR! Sorry, could not resist! Cheers!
  17. If you had a SCSI system, you wouldn't have to ask that question! Anyways, there are a plethora of technical papers on the controllers you specify so it may be possible to sift through all those pages and find out if TCQ is actually available in your environment. Of course, then you have to determine if it is actually active! You may find of use! In closing, I found the following images from a frustrated user quite entertaining! Cheers!

    WD 72GB Raptor coming next month?

    A 72 GB / platter Raptor! Transfer would probably start out close to 100 MB/S?! Cheers!

    Raptors are killing me :) !?!?!?!

    The performance of retail raptors using the included SATA card flashed to a RAID card can be seen here: 36GB Raptor in RAID 0 results I cannot imagine all of these disks being defective. Sorry to say, but it sounds like the problem is obvious Cheers!

    serial ATA in a server

    What if you wanted eight, ten or twelve disks? It would require that many connectors plus a cable for EACH drive! Messy and inefficient. The bandwidth argument is invalid as well. The FASTEST (15K) disks on the outermost tracks do 1/2 what SATA is capable of... SATA is OK if you're running a very low end (entry level) server. Anything mid range and higher should be running SCSI PERIOD! Cheers!

    Is this drive better than the Seagate X15.3? I'm looking to have four or more of these in a workstation so if they are fairly quiet that would be a plus... Idle whine is OK, seek rumble is OK. HUM is NOT ok! The X1536LP's that are currently in use have a resonant hum that will drive most sane people past GeForce FX 5800 Ultra (Flow FX) crazy! How's the speed? Cheers!

    Is this the same drive in the SR database that's at the top? (aka the fastest HDD) Cheers!
  23. First and foremost let me clear a few things up... DNS is working both ways 100%. Netstat shows NO problems. Users log on fast with no lag. (Workstations are XP Pro SP1) We have this problem with both a Windows 2000 Server AND a Windows 2003 Server! IF we set the machine up as a standalone server with accounts matching those of the workstations, speed is very fast. Once we create the domain and have users logging in, the slowdowns start. The slowdowns occur when opening a zip file with 200 small images, for example. Extract that to another folder on the users's share. EXTREMEMLY slow as in it takes MINUTES. If done locally on the machine, it takes 5 sec TOP. When done through a mapped drive to the server (standalone) it's very fast like it should be. Now for the interesting part. If I access the server by \\server\users\username\etc it's fast. Through the mapped drive it's slooooow. ONLY when the server is a DC. Hardware...most workstations are dual Xeons 2.4GHz+ with 2~4GB RAM, SCSI, etc. Server is mid range Xeon MP with 6GB RAM, 12 15.3 RAID 50 etc. All connections are 1000 Mbps FD. File copy speed from WS to S and vice versa is 400~600 Mbps average. NOT hardware related! Speeds only drop when server is a domain controller! Very strange. I've searched the newsgroups and have found people having similar issues but there seems to be no real solution. This is ridiculous. We bought 2003 Enterprise w/ 100 users figuring the problem would be fixed. (The server is VERY fast as a standalone) NOPE! Any ideas? -DAK-

    Any Active Directory Experts Here?

    BINGO! We have a winner here folks! I tried this and once it took affect (replication cycle) it worked! Speeds in the domain are the same as standalone server! This is excellent indeed! Thanks a million! As for the other suggestions... I knew it wasn't DNS as I mapped out the entire network to one machine via IP addresses on everything. Same slowness. I could open up 100 instances of ping PDC -l 64000 -t and all results were <10 mS. Bandwidth was never an issue for the most part. Ok, this problem licked. Thanks guys. -DAK-

    Any Active Directory Experts Here?

    Ok the zip file was an example of many slowdowns... If I delete a folder containing lots of small files, they are deleted with the speed similar to that observed when deleting files from a floppy! I'm not kidding! CPU util on WS and Server is zilch. If I open a large spreadsheet or even word document and make a change and save it the save takes 15 sec or so. Once again, same thing, same hardware with no domain is instantaneous! Everyone says problem is DNS which it is not. Only thing I know when DNS is messed up is logons take FOREVER which they don't. Most of the time if you blink you cannot even see the logon script boxie pop up... Anything in particular I should be looking for?Thanks! -DAK-
