Sometimes it is necessary for me to run Winloose NT 4 on the Pro and it is nice when I can access files from B. But the samba performance is very bad. When the Pentium Pro machine (A) copies files from B than only 200 KB/s are achived. FTP from A to B and vice versa as well as the TCP benchmark tcpblast show the almost full performance of 1.1 MB/s. But when I run smbclient I only get 330 KB/s. smbclient locally on B delivers 5 MB/s or more. Therefore my question: Why is samba so slow when the network connections between the two machines are ok? What's going on there? On A I'm running 3.0-current, on B 2.2.2.

Do you have "-O TCP_NODELAY" on the command line for smbd (or the equivalent in the smb.conf)? Without this, the typical symptoms are very poor performance where the client is a faster machine than the server. (note also that in old versions of the FreeBSD port of samba, this option was ignored silently due to a missing include file; recent versions in ports seem to be OK).

Thanks! This options had a big effect. Performance increased to 1 MB/s. :-) BTW, what can I do with my NFS? I get only 600 KB/s when reading files over NFS (the server again the smaller K5 machine, the client the fast P6 machine).

[running 2.2.2-RELEASE], My IBM DCAS-34330 runs nice & cool, but first one got unrecoverable sector errs after transporting the system 20 kilometres in my car & then thrashing it (pc not car :-) for a while, installing my site master data there.

ECC should work on such memory (I'm doing it on a PPro system with 8 x 32MB). Make sure it true parity memory. Also, the memory could be bad. Turning parity and/or ecc on could be working! The problem just isn't noticed with ecc/parity off. Also, make sure the SIMMs have 24 or less chips on them.

Doing a 'make world' always results in sig 11 errors or strange gcc errors. Changing memory access from 60ns to 70ns resolves all the problems.

MegaHaus, Bason, FPE, and a thousand other ``Grey Market Dealers'' are selling you OEM drives, and/or dumped inventory when there price is _below_ the Quantum controller distribution price, plain and simple, so when you see all those disks drives at super deal prices you _ARE_ taking a risk you may not be able to get warranty service on the drive. Quantum is pretty good about dealing with this, they don't like upset customers who will bad mouth them and never buy another Quantum drive, so they do sometimes repair OEM drives purchased through the ``Grey'' channel. Seagate on the other hand well flat out tell you, no way, you have to go deal with so and so (the OEM who the drive was original sold to by Seagate) if you want warranty (OEM drives often only carry a 1 year warranty to the OEM from the manufacture.) Now you know why my disk prices tend to run 10 to 20% above what the discounters are, I buy from official Quantum listed distributors, will put the fact that thier is a 5 (or 3 if PC division disks) year warranty on the product _AND_ will go to bat for you with Qantum should warranty service be required outside the 1 year AAI warranty (all products from AAI have a return to AAI 1 year warranty, few if any questions asked.) should Qauntum not give you an RMA number on your first call to them. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation, Inc.

An interesting situation worth knowing about. With this motherboard: Gigabyte GA586A, rev 1.22C, based on the SiS 5571. The Cyclades 16Ye board, based on the PLX PCI9060ES, does not function correctly. More specifically, after receiving the first interrupt (incoming character, outbound character, change in handshaking state etc.) the system locks up "moderately" tight - it still responds to ARP requests, pings, etc., and CapsLock still works (but not NumLock?!), but no user processes run, no console output, no disk activity etc. These symptoms were observed consistently on a set of test hardware comprising two Cyclades cards and two of the above motherboards. Testing with Intel 430VX-based boards did *not* show the same symptoms. We were unable to test with any other operating systems, as we don't believe in congress with the devil. The Digital ethernet cards were removed without effect.

Support for the 75xx chips in XFree86 is not good. You will have to turn to Xi Graphics and their XInside product to get a working server. Note that even this server has serious problems with many 7543 implementations, and you may be forced to run with no acceleration enabled in order to achieve a decent picture. By contrast, laptops featuring the C&T 655xx chips are quite well supported.

First some background info : We're doing Vision Related research using a Binocular Stereo Camera called "BiSight" (http://www.HelpMateRobotics.com/RC_components/RC_frameset.htm). We're planning to assemble a machine (PC) for the purpose of building an active vision system that uses : 1. BiSight Binocular Camera 2. Stereo Video Capture Card - FreeBSD Driver available!!!! (http://www.iijnet.or.jp/argocraft/vcb/capture-e.html) - No detailed information in English. 3. Ofcourse, FreeBSD as the OS. BiSight Controller is a Delta-Tau PMAC (4/8 Axis Programmable Multi-Axis Controller) (http://www.deltatau.com/pmacspec.htm) Since we're aiming at real time Image Processing, we've decided to go for a Pentium II based PC. Infact it is quite difficult to do this for 30 frames/s without the support of hardware image processor. But we would like to go for the maximum frame rate that is possible without this special hardware support. (say at least 10 or 15 frames/s) I would greatly appreciate any recommedations/suggestions/advice on getting the necessary hardware for this purpose. 1. Pentium II (Single or Dual CPU) 2. Motherboard (BIOS ..) 3. Chip Set (440LX ?) - Limitations on PCI Bandwidth 4. Memory (EDO or SDRAM) 5. Any other relevant piece of h/w In particular I would like to know what pitfalls, if any, I should be looking at. Thanks a lot in advance. Regards, Ajith Pasqual.

Most RAID systems do not allow you add drives to an existing array. Generally you have to tear down the array setup, and make a new one, losing all previous data. Some can merge in a new drive preserving data, but is time consuming, and array has to be offline. > generally i'm interested in raid5. > > 3 drives is the minimum, right? Yes. > then 4th drive gives the hot spare. how about 5th? 6th? 7th? Not necessarily. You can have anything over 3, not including spares. Generally, 3 or 5 drives is the best choice. Making an array with too many drives will really hurt write performance. > a graph would be nice. There is a simple formula for this that calculate the amount of usable space on any RAID-5 array given the number and size of each drive. For some reason it elludes me now. > what about unstandard raid's (6 7 8 9 10, some of those might not even > exist, but i believe i've seen at least 6 7 and 10) They are non-standard and propietary. Who knows what they do. Generally they are just tweaked RAID-5 type systems, but some sales drone decided to give them a higher number, because bigger is better, and most customers buy into that. > mickey > > Tom From owner-freebsd-hardware Fri Oct 17 11:45:13 1997 Return-Path: Received: (from root@localhost) by hub.freebsd.org (8.8.7/8.8.7) id LAA29432 for hardware-outgoing; Fri, 17 Oct 1997 11:45:13 -0700 (PDT) (envelope-from owner-freebsd-hardware) Received: from ns.sbbs.se (ns.sbbs.se [193.13.199.1]) by hub.freebsd.org (8.8.7/8.8.7) with SMTP id LAA29426 for ; Fri, 17 Oct 1997 11:45:06 -0700 (PDT) (envelope-from martin@filex.se) Received: from [130.244.109.41] by ns.sbbs.se (NTMail 3.02.13) with ESMTP id ua541574 for ; Fri, 17 Oct 1997 20:45:21 +0200 Message-ID: <3447B2B7.6445@filex.se> Date: Fri, 17 Oct 1997 20:47:19 +0200 From: Martin Nilsson X-Mailer: Mozilla 3.01 (WinNT; I) MIME-Version: 1.0 To: freebsd-hardware@FreeBSD.ORG Subject: FreeBSD and IDE drives Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-hardware@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk How good are the IDE/ATA drivers in FreeBSD? I'm running 2.2.1 on a 430TX based motherboard with a 4.3GB Quantum Ultra DMA harddrive. When I boot the system FreeBSD detects the PCI IDE controller but doesn't assign a driver for it, instead the IDE controller is detected and used when the ISA bus is scanned. How fast is the communication between the drive and controller? The drive has a maximum thruput of about 10MB/s Would there be any benefit if the driver used the PIIX4 chip in DMA busmaster mode? /Martin From owner-freebsd-hardware Sat Oct 18 14:28:21 1997 Return-Path: Received: (from root@localhost) by hub.freebsd.org (8.8.7/8.8.7) id OAA05359 for hardware-outgoing; Sat, 18 Oct 1997 14:28:21 -0700 (PDT) (envelope-from owner-freebsd-hardware) Received: from isgate.is (isgate.is [193.4.58.51]) by hub.freebsd.org (8.8.7/8.8.7) with ESMTP id OAA05350 for ; Sat, 18 Oct 1997 14:28:16 -0700 (PDT) (envelope-from totii@est.is) Received: from eh.est.is (eh.est.is [194.144.208.34]) by isgate.is (8.7.5-M/) with ESMTP id VAA05452; Sat, 18 Oct 1997 21:27:55 GMT Received: from didda.est.is (totii@ppp-21.est.is [194.144.208.121]) by eh.est.is (8.8.5/8.8.5) with SMTP id VAA15710; Sat, 18 Oct 1997 21:26:16 GMT Message-ID: <344929B6.41C67EA6@est.is> Date: Sat, 18 Oct 1997 21:27:19 +0000 From: =?iso-8859-1?Q?=DEor=F0ur?= Ivarsson X-Mailer: Mozilla 3.01Gold (X11; I; FreeBSD 2.2.2-RELEASE i386) MIME-Version: 1.0 To: mika ruohotie CC: hardware@FreeBSD.ORG Subject: Re: raid References: <199710171352.PAA11906@shadows.aeon.net> Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-hardware@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk mika ruohotie wrote: > > uh, is there documentation exactly how much more disk space one > gains when plugging another drive into raid system. > > generally i'm interested in raid5. > > 3 drives is the minimum, right? > > then 4th drive gives the hot spare. how about 5th? 6th? 7th? > > a graph would be nice. > > what about unstandard raid's (6 7 8 9 10, some of those might not even > exist, but i believe i've seen at least 6 7 and 10) > > mickey I installed Mylex EISA raid controllers in two Novell fileservers using 500MB disks serveral years ago. The installation gave me 2GB using 5 disks 2.5GB using 6 disks. The final installation in both cases was using 6 disks and the seventh for online backup. Thordur Ivarsson thivars@est.is
