    Pci Bus Traffic Concerns

    I think the GigE is on PCI-X bus A @ 100MHz. And the SATA is connected to the 8111 via the bog standard 32-bit PCI bus @ 33MHz. If I'm not mistaken, you can only have 1 PCI-X device on the bus if you run at 133MHz... As soon as you add two devices to the bus, you will have to drop down to 100 or 66MHz.

    Pci Bus Traffic Concerns

    I wouldn't go so far as to call Tyan a bunch of crooks, but I have been left a little miffed with their design choices. I mentioned this in another thread, but to recap, I have a Tyan Transport GX28 1U server case with built-in s2880 Tyan thunder k8s m/b. I assumed from the start that the on-board SCSI would be easy to upgrade to RAID using ZCR. Well, lo and behold, the ZCR slot is inaccessible in this server. So, I decided to buy an LSI 320-1 RAID card (I wish they had 1X versions), and on trying to fit this card in the server, what do I find?... A tall capacitor makes it impossible to fit (ultimately i had to strip the card of its backplane and fit it in another slot --messy). Ultimately, this was not the right m/b for this 1u server. On the positive side, their server case is very well built. The hot swap drives, the SCA backplane, the cooling/air flow design, all top-notch. There aren't that many 1U cases that support 4x hot-swap scsi, with dvd-rom and floppy. The only thing missing is a scsi connector at the back for external devices.

    Megaraid 320-1 Problem

    False alarm. ...Got it to work. Started from scratch, with only 1 vol per array, and re-initialised. Also turned off on-board scsi.
  4. I have a LSI MegaRAID 320-1 and Windows Server 2003 setup can't find any connected hard drives forcing it to abort! I have tried the F6 3rd party driver installation to no avail. Has anyone installed windows on a hdd connected to MegaRAID controller? The drives work perfectly when connected to the on-board scsi and Windows finds them without problem. As soon as I connect the drives to the MegaRAID, the drives are detected by the megaRAID setup, but not Windows... Help! My drives:- (all ultra320 scsi SCA) 3x seagate 36GB drives in RAID-5 array 2 logical volumes; the first set to boot 1x seagate 15GB alone in RAID-0 1 logical volume My controller:- LSI logic MegaRAID 320-1 in a riser card on pci slot 2 (the only available one). My system:- dual opteron 244 2GB Infineon DDR 333 Tyan thunder k8s with on-board scsi

    Disk Imaging A Raid Partition

    I read on that their True Image 7 suports "all levels of RAID". I haven't tried True Image myself but the reviews are all very good.

    Ibm Gxp Fiasco Secrets Revealed !

    I've still got two GXP drives (30GB and 45GB) in my home server. Apart from running extremely hot, they haven't exhibited any problems. They must be two years old by now, maybe older, and have taken a lot of abuse. It's only a matter of time...
  7. Try clearing the cmos, re-flashing the bios to an older version, and making sure the usb option in the bios is enabled...

    My First Computer

    My timeline with PCs + some memorable games I played at the time... 1987 Sinclair QL (M68008, built-in twin minidrive, QDOS) --given away 1989 Commodore PC40 (IBM PC compat., 80286, 40MB hdd) --dumped (Leisure Suit Larry, Police Quest) 199x Toshiba 386 SX Laptop (Visual Basic 1.0 on Windows 3.1) 1993? 486DX2 66MHz, 1MB --dumped 120MB hdd on controller with 0.5MB cache Cheetah 2theMax gfx on Vesa Local Bus!

  9. Seagate is about to launch their SAVVIO 2.5" drives:,4149,1493475,00.asp Interesting points:- * 36.7GB and 73.4GB capacities * 2.5" wide, 1.5 cm high (70% smaller than their 3.5" drives) * 40% less power than equivalent 3.5" drive * MTBF: 1.4 million hours * Serial SCSI (SAS), 2Gbit Fibre Channel or Ultra320 SCSI Can't wait...

    Seagate 10k.6 4mb Or 8mb Cache

    Thanks, I do have a SCA backplane, so all is ok. At the end I placed my order at provantage instead, despite the hdd being more expensive. The controller and shipping cost tipped the scales in their favour.
  11. Uhm, just a quickie... Check the following links:- The first coming from dealtime, the second just browsing the site. Do you also get a price difference? Okay, but now the strange thing. They mention a 4MB buffer, but checking the Seagate site, the drives should have 8MB cache. $139 is a pretty good deal for these drives. Do you think they might be refurbished or older models? I'm about to get two of these, another RAID controller, and a bog standard lvd cable (why are these so hard to find...).

    Flexible Riser Cards

    Yeah, I wanted a cheap solution having already gone way over budget. However, after much brain-prodding and teeth-gnashing, I've settled on getting a proper RAID card. It's just a shame to have to abandon the on-board SCSI. Makes me wish I had bought a 2U case because then at least I could attach more external devices.
  13. I bought a Tyan Transport GX28 1U with s2880 m/b thinking that a ZCR card would simply work in the riser card provided, but much to my chagrin, I found that pci slot 1 (on which the riser lies) does not support ZCR! What a strange design decision to make the inaccessible bottom slot ZCR compatible... There's two possible solutions: 1. Disable on-board scsi and get a new PCI-X raid card (expensive). 2. Get a flexible riser card to replace the fixed one provided (cheap). And so I come to the question: Where can I get a PCI-X *flexible* riser-card for a 1U case that supports 64-bit PCI-X 3.3V @ 100 MHz? Thanks

    Pxe Server

    I'm running Windows Server 2003 and I want to boot up several clients remotely via PXE. For the moment, I want them all to boot DOS and run a script automatically. Here are the steps as I understand them:- 1. Client obtains IP + subnet mask + default gateway via DHCP 2. Client obtains bootstrap program name 3. Client retrieves bootstrap image via TFTP using the name obtained from (2) 4. Client executes bootstrap program (i.e. loads DOS) 5. Client executes script (via autoexec.bat) Is this correct? Here are the problems:- * How do I configure the TFTP daemon that comes with RIS in Windows? * How do I configure the DHCP server to send a specific bootstrap image name depending on the MAC address of the client? Or alternatively, How else can I do remote + automated installations over a network? Thanks guys.

    Centrino Mobile Technology?

    I think I read, a few weeks back, that the Centrino chipset has already been updated to support 802.11g and that it should feature in notebooks shipping in Q1 of this year. (or am I mistaken?) Further down the line, in Q2, we'll have "Dothan", the follow-up to the Pentium M. It'll accomodate a larger 2MB L2 cache and draw less power than the current range. It will launch @ 1.5GHz and go beyond 2GHz soon after. Centrino 2 codenamed "Sonoma" will probably be launched in Q3. Expect up to 25% Pentium M price cuts as we near the launch date.
