I think that controller (with cache and RAID capabilities) lists for around $1200 US. I imagine street price will fall in the $1000 area. They have info on the Web site (http://www.dpt.com/).

The hardware definitely looks good on paper, and the price point starts around the level of the current crop of Adaptecs. As I told Mark at DPT, FreeBSD already has the software muscle to be the top contender as an NFS server, now it needs some equally potent hardware to back it up. 42 of those new 23GB Seagate drives per controller, four controllers per machine == 3TB of *usable* filesystem space (hi, Satoshi!). :) -- Brian Tao (BT300, taob@io.org, taob@ican.net) Systems and Network Administrator, Internet Canada Corp.

It certainly is outside the realm of FreeBSD's traditional ISP and home markets (funny to talk about "traditional" on such a young BSD), but I would imagine research and industrial environments would benefit from such a beast.

It would be far better for the SCSI system writers to > place striping across controllers within that layer (as is > done under Linux). Can you clarify this part, since I don't understand what design is far better than ccd unless it is addressing a different problem and doesn't affect ccd. It makes sense to support striping against arbitrary block devices, as is done in ccd. This should not percolate down into individual controller devices (aside from possibly some get-capability types of functions with good defaults) since you'd like to just take an existing driver and plug it into the ccd system without any changes. It makes sense to stripe directly across a device that has special hooks for striping with direct driver support, bypassing ccd and using it as the designer intended. Is this what you mean? This isn't an argument against ccd as much as a statement that to use your controller technology properly you need a proper driver. (You could also mean that we need a layer of RAID control with a standard interface that is layered on top of a driver, and that driver could be either a ccd derivative or a board with RAID support, but I don't think you mean that). -- Peter Dufault Real-Time Machine Control and Simulation HD Associates, Inc.

Used 2.1R No luck there, it looks like the ahb driver does not 'see' it on boot. Second attempt, hooked it up to a Adaptec 1542B that also serves the boot disk. Found it! OK, disklabel and newfs. 1 hour and 20 minutes later I had this 28+ Gb filesystem... Only problem sofar: 'df' reports a negative 'avail' number. Percentage is also -0% (noi typo). I'll try to find out why this happens. Any known problems with disks this big? When it comes to big 'disks' I can currently make them up to 14*4.3Gbyte in size...

I perused the archives, but I never got a definative answer: where do we stand on support for disks with a blocksize other than 512 bytes? I notice from looking at the OS code that the driver explicitly screens out drives with different (!512) blocksizes. The sd driver code looks pretty simple. are there other complications from just modifing the code as it's been done in the cd-rom driver? Thanks for the info, Robert Sexton.

I've got some patches around that might fix it, submitted by the author of the `od' driver. I've never got round to test them anyway, but after a Great Cleanup, my MO drive at least takes my one and only 1024-byte cartridge again. UFS is far more tricky to fix than just the drivers only. This is why it works for CD-ROMs: they don't apply to UFS, only to ISO9660. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) From owner-freebsd-scsi Wed May 22 12:20:22 1996 Return-Path: owner-freebsd-scsi Received: (from root@localhost) by freefall.freebsd.org (8.7.3/8.7.3) id MAA19451 for freebsd-scsi-outgoing; Wed, 22 May 1996 12:20:22 -0700 (PDT) Received: from linux4nn.gn.iaf.nl (root@linux4nn.gn.iaf.nl [193.67.144.34]) by freefall.freebsd.org (8.7.3/8.7.3) with SMTP id MAA19446; Wed, 22 May 1996 12:20:13 -0700 (PDT) Received: from uni4nn.iaf.nl (root@uni4nn.iaf.nl [193.67.144.33]) by linux4nn.gn.iaf.nl (8.6.9/8.6.9) with SMTP id VAA22555; Wed, 22 May 1996 21:20:03 +0200 Received: by uni4nn.iaf.nl with UUCP id AA21346 (5.67b/IDA-1.5); Wed, 22 May 1996 21:19:38 +0200 Received: by iafnl.es.iaf.nl with UUCP id AA05109 (5.67b/IDA-1.5); Wed, 22 May 1996 21:14:16 +0200 Received: (from wilko@localhost) by yedi.iaf.nl (8.6.12/8.6.6) id VAA01659; Wed, 22 May 1996 21:09:32 +0200 From: Wilko Bulte Message-Id: <199605221909.VAA01659@yedi.iaf.nl> X-Organisation: Private FreeBSD site - Arnhem - The Netherlands Subject: Tape performance measurements To: jmb@freebsd.org, freebsd-scsi@freebsd.org (FreeBSD SCSI hackers) Date: Wed, 22 May 1996 21:09:32 +0200 (MET DST) X-Mailer: ELM [version 2.4 PL23] Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Sender: owner-freebsd-scsi@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi there ( I copied -scsi because I think there might be some interest there) Below is the essence of Jonathan's message that triggered my measurements. > > > if you have a tape drive that your use successfully > > > plese send me the dmesg output for the drive > > > any quirks that the drive exhibits > > > any tricks you needed to get the drive working Environment: Asus TP4XE, P100, 16 Mbyte, 2.1R, used with the -current dump (has the kbytes/sec stats). 2Gb 5400 rpm Quantum on NCR810, NCR810 shared the same SCSI bus with the tapes. DLT measurements: ----------------- The dmesg entry: (ncr0:6:0): "DEC TZ87 (C) DEC 9B3C" type 1 removable SCSI 2 Uncompressed, 10Gb mode. bash# ./dump 0ubBf 32 10000000 /dev/rst2 /local DUMP: finished in 717 seconds, throughput 1247 KBytes/sec Compressed, 20Gb mode bash#sh# ./dump 0ubBf 32 10000000 /dev/rst2 /local DUMP: finished in 630 seconds, throughput 1418 KBytes/sec Slightly hacked dump, allows blocking 64 bash# ./dump 0ubBf 64 10000000 /dev/rst2 /local DUMP: finished in 657 seconds, throughput 1360 KBytes/sec Comments: I had expected the 64 blocking to be better than the 32. My experience is that the compression works better and the drive is therefore faster. I cannot keep the tape streaming, start/stop operation hurts a DLT's performance really big. On a Sun Sparc 20 with Solaris 2.5 with the (identical) disk and the DLT on _seperate_ SCSI buses I got almost 1.9 Mbyte/sec for an ufsdump of /usr. When tape and disk were on the same bus on the Sun I also had start/stop operation, and went down to something like 1.4 Mbytes/sec. (Somebody wants to donate me a second NCR810 ? 8-) Exabyte 8200 measurements: -------------------------- The dmesg entry: (ncr0:5:0): "EXABYTE EXB-8200 2687" type 1 removable SCSI 1 DUMP: finished in 700 seconds, throughput 227 KBytes/sec Comments: If I remember correctly the Exabyte is speced for 240kbytes/sec.

This disk, like some other DEC disks, does *not* spin up when powered up. Other DEC disks have jumpers to change this, the RZ24 doesn't seem to have them. When I boot DOS or enable the AHA2940's BIOS, I can hear the drive spin up and see the driver wait for it to become ready. If I don't enable the AHA2940's BIOS and I boot FreeBSD (2.1-RELEASE), the disk is not spun up and the mount fails (note that the mount attempt actually causes it to start spinning, but the FreeBSD driver obviously does not wait at that time, the SCSI_DELAY wait occurs *before* the mount attempt). If I soft reboot (CTRL-ALT-DEL) the machine at this point, the next boot completes OK. >From the FAQ, I can guess that the SCSI inquiry FreeBSD sends before waiting SCSI_DELAY does *not* cause the disk to start, and then the subsequent mount attempt fails. I don't want to enable the AHA2940 BIOS because I want to save high memory for DOS usage (this is a multi-OS machine) and I'd really love to have this machine boot unattended. How can I make FreeBSD issue a "start unit" command to the disk *before* it waits for SCSI devices to settle ? From my reading of ./sys/scsi/sd.c and cd.c, it seems to me that such a thing is done for CDROM units, but not for disks. Another possibility I imagined would be to add a scsi(8) command (and a sleep(1)) at the very beginning of /etc/rc to send a "start unit" to the disk. But: 1) this really is an ugly hack (hardcoded device names in /etc/rc) 2) I have not even managed to use scsi(8) to do that, all my attempts (like "scsi -f /dev/rsd0c -c "1b 0 0 0 1 0") have at best produced i/o errors. I even have locked up the machine tight sometimes (SCSI bus hung) Would someone please enlighten me ?

Ah, ok. We're still in need for a good design of how to share the CD-ROM driver with the WORM driver (since all CD-R devices constitute a superclass of CD-ROM). So we should try to find a good way how to arrange for this functionality. Basically, a `pd' driver would be nothing else than an `od' driver on LUN 0, and a `cd' driver on LUN 1. The only specific code would be the driver probe. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) From owner-freebsd-scsi Thu May 23 23:51:46 1996 Return-Path: owner-freebsd-scsi Received: (from root@localhost) by freefall.freebsd.org (8.7.3/8.7.3) id XAA03380 for freebsd-scsi-outgoing; Thu, 23 May 1996 23:51:46 -0700 (PDT) Received: from irz301.inf.tu-dresden.de (irz301.inf.tu-dresden.de [141.76.1.11]) by freefall.freebsd.org (8.7.3/8.7.3) with SMTP id XAA03356; Thu, 23 May 1996 23:51:38 -0700 (PDT) Received: from sax.sax.de by irz301.inf.tu-dresden.de (8.6.12/8.6.12-s1) with ESMTP id IAA25267; Fri, 24 May 1996 08:51:35 +0200 Received: by sax.sax.de (8.6.12/8.6.12-s1) with UUCP id IAA17502; Fri, 24 May 1996 08:51:34 +0200 Received: (from j@localhost) by uriah.heep.sax.de (8.7.5/8.6.9) id IAA21885; Fri, 24 May 1996 08:41:50 +0200 (MET DST) From: J Wunsch Message-Id: <199605240641.IAA21885@uriah.heep.sax.de> Subject: Re: SCSI hostadapter To: freebsd-hackers@freebsd.org (FreeBSD hackers) Date: Fri, 24 May 1996 08:41:49 +0200 (MET DST) Cc: freebsd-scsi@freebsd.org Reply-To: freebsd-scsi@freebsd.org In-Reply-To: <199605232213.PAA08500@phaeton.artisoft.com> from Terry Lambert at "May 23, 96 03:13:34 pm" X-Phone: +49-351-2012 669 X-PGP-Fingerprint: DC 47 E6 E4 FF A6 E9 8F 93 21 E0 7D F9 12 D6 4E X-Mailer: ELM [version 2.4ME+ PL17 (25)] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-freebsd-scsi@freebsd.org X-Loop: FreeBSD.org Precedence: bulk As Terry Lambert wrote: > I believe the NCR 53c7xx series (I don't recognize the "53C700-66" > in particular, though) are not supported because they are very > low end components, for which no one has written a driver. Reminds me: does anybody have any information about the 53C400? I've got a couple of these boards sitting on a shelf, they used to accompany HP ScanJets. I don't think they will be anything that can be called performant, but just out of curiosity...

The page on which the spinup parameter is is on a vendor specific page if i recall correctly. So if you reference it in the /usr/share/misc/scsi_modes you might run into big troubles if some other disk vendor use the same page, for something entirely different, wich they might since its vendor specific. You could get your disk to agressivly not want to cooperate if you change the parameter on a disk which use the same page for something entirely different, couldn't you? regards/ Joakim From owner-freebsd-scsi Fri May 24 11:53:19 1996 Return-Path: owner-freebsd-scsi Received: (from root@localhost) by freefall.freebsd.org (8.7.3/8.7.3) id LAA15817 for freebsd-scsi-outgoing; Fri, 24 May 1996 11:53:19 -0700 (PDT) Received: from schizo.cdsnet.net (schizo.cdsnet.net [204.118.244.32]) by freefall.freebsd.org (8.7.3/8.7.3) with ESMTP id LAA15812 for ; Fri, 24 May 1996 11:53:17 -0700 (PDT) Received: from localhost (mrcpu@localhost) by schizo.cdsnet.net (8.7.5/8.6.12) with SMTP id LAA07994; Fri, 24 May 1996 11:53:53 -0700 (PDT) Date: Fri, 24 May 1996 11:53:52 -0700 (PDT) From: Jaye Mathisen To: hdalog@zipnet.net cc: Joakim Henriksson , af@biomath.jussieu.fr, freebsd-scsi@freebsd.org Subject: Re: How to send "start unit" to disk during boot?

Or rzspinup.exe, I think that should work for all of them. Uses an ASPI interfaced SCSI card. If you can't find the tools I can send them to you. The newer DEC disks are either made by Seagate or Quantum. Every DEC disk that is labeled 'SWX.....' is a Storageworks Multivendor disk that does staggered spinup on powerup. The disks labeled 'RZ...' are the on-base (read: for DEC systems) drives that need a spinup command. The tendency is to go to staggered spinup for all DEC's drives Wilko (aka bulte@stowks.enet.dec.com) _ __________________________________________________________________________ | / o / / _ Wilko Bulte email: wilko@yedi.iaf.nl |/|/ / / /( (_) Private FreeBSD site - Arnhem - The Netherlands -------------------------------------------------------------------------------- From owner-freebsd-scsi Fri May 24 12:17:29 1996 Return-Path: owner-freebsd-scsi Received: (from root@localhost) by freefall.freebsd.org (8.7.3/8.7.3) id MAA18704 for freebsd-scsi-outgoing; Fri, 24 May 1996 12:17:29 -0700 (PDT) Received: from linux4nn.gn.iaf.nl (root@linux4nn.gn.iaf.nl [193.67.144.34]) by freefall.freebsd.org (8.7.3/8.7.3) with SMTP id MAA18697 for ; Fri, 24 May 1996 12:17:24 -0700 (PDT) Received: from uni4nn.iaf.nl (root@uni4nn.iaf.nl [193.67.144.33]) by linux4nn.gn.iaf.nl (8.6.9/8.6.9) with SMTP id VAA29504; Fri, 24 May 1996 21:17:00 +0200 Received: by uni4nn.iaf.nl with UUCP id AA12788 (5.67b/IDA-1.5); Fri, 24 May 1996 21:16:15 +0200 Received: by iafnl.es.iaf.nl with UUCP id AA02206 (5.67b/IDA-1.5); Fri, 24 May 1996 20:48:26 +0200 Received: (from wilko@localhost) by yedi.iaf.nl (8.6.12/8.6.6) id TAA20959; Fri, 24 May 1996 19:29:22 +0200 From: Wilko Bulte Message-Id: <199605241729.TAA20959@yedi.iaf.nl> X-Organisation: Private FreeBSD site - Arnhem - The Netherlands Subject: Re: dump and 32blocks limit To: joerg_wunsch@uriah.heep.sax.de Date: Fri, 24 May 1996 19:29:22 +0200 (MET DST) Cc: freebsd-scsi@freebsd.org, andreas@knobel.gun.de In-Reply-To: <199605232113.XAA19528@uriah.heep.sax.de> from "J Wunsch" at May 23, 96 11:13:03 pm X-Mailer: ELM [version 2.4 PL23] Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Sender: owner-freebsd-scsi@freebsd.org X-Loop: FreeBSD.org Precedence: bulk > As Wilko Bulte wrote: > > > I'm not absolutely sure this is SCSI-only related but: > > > > I grabbed the -current dump sources and found a 32 block limit builtin > > there.

The CD-R devices use mode pages in the 0x2X range. I always thought that there's a vendor-specific reserved range, too bad that DEC seems to violate the specs here. So i'm not sure whether this one should be committed to the source tree or not. What do other people think? > J"org, I didn't need the source code patch for sd.c you suggested, so > I can't tell.

The scsi_start_unit() is supposed to wait until the drive reports that it has spun up. Maybe since this is the first spinup after the power cycle, it still reports a unit attention? It would be interesting to know why the existing code didn't work -- so we could fix it. (For the `od' driver, i definately needed to make this change. I've gone further in my experiments and do a scsi_stop_unit() on each odclose(), but will yet wait for some comments by the author of od(4).) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) From owner-freebsd-scsi Fri May 24 13:42:36 1996 Return-Path: owner-freebsd-scsi Received: (from root@localhost) by freefall.freebsd.org (8.7.5/8.7.3) id NAA25551 for freebsd-scsi-outgoing; Fri, 24 May 1996 13:42:36 -0700 (PDT) Received: from hda (ip5-max1-fitch.zipnet.net [199.232.245.5]) by freefall.freebsd.org (8.7.5/8.7.3) with SMTP id NAA25542 for ; Fri, 24 May 1996 13:42:27 -0700 (PDT) Received: (from dufault@localhost) by hda (8.6.11/8.6.9) id QAA24715; Fri, 24 May 1996 16:41:19 -0400 From: Peter Dufault Message-Id: <199605242041.QAA24715@hda> Subject: Re: How to send "start unit" to disk during boot?

Well, sometimes I had a SUN 4mm DAT (Archive Python) at home. When doing backups with dump everything seemed to be fine. I could choose blocksizes of about 96 blocks (as it's usual on Sun's). But when I tried to read those tapes with restore, I got an error message (forgot which exactly), you could perhaps browse the -current list for my e-mail... The result was, that I was only able to restore dumps that were made with a blocksize <= 64 blocks if I remember exactly. Untli this bug is fixed somewhere in kernel land I had the idea to disallow blocksizes >64 blocks in dump ... I think people wouldn't find it funny, if they are unable to restore their backups in case they saved the time of verifying a dump ;-)) Don't ask me, what's exactly the reason for this ...

Now look at the 64 KB physio limitation: your 96 KB has been accepted by dump(8), but physio(9) split it into one 64 KB block (due to its limit), and one 32 KB block. This gives you a tape with alternate 64/32/64/32 KB blocking, nothing you would really like to have... So we should bump the limit to 64 KB, and explain the limitation of physio in the man page (until it's been fixed -- which should remain a goal, think of importing tapes with > 64 KB blocking). -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) From owner-freebsd-scsi Sat May 25 14:23:21 1996 Return-Path: owner-freebsd-scsi Received: (from root@localhost) by freefall.freebsd.org (8.7.5/8.7.3) id OAA14983 for freebsd-scsi-outgoing; Sat, 25 May 1996 14:23:21 -0700 (PDT) Received: from irz301.inf.tu-dresden.de (irz301.inf.tu-dresden.de [141.76.1.11]) by freefall.freebsd.org (8.7.5/8.7.3) with SMTP id OAA14976 for ; Sat, 25 May 1996 14:23:13 -0700 (PDT) Received: from sax.sax.de by irz301.inf.tu-dresden.de (8.6.12/8.6.12-s1) with ESMTP id XAA14653; Sat, 25 May 1996 23:21:50 +0200 Received: by sax.sax.de (8.6.12/8.6.12-s1) with UUCP id XAA08518; Sat, 25 May 1996 23:21:50 +0200 Received: (from j@localhost) by uriah.heep.sax.de (8.7.5/8.6.9) id XAA27362; Sat, 25 May 1996 23:06:37 +0200 (MET DST) From: J Wunsch Message-Id: <199605252106.XAA27362@uriah.heep.sax.de> Subject: Re: kern/1245: scsi tape driver write-protect and eject handling is broken To: freebsd-scsi@freebsd.org Date: Sat, 25 May 1996 23:06:37 +0200 (MET DST) Cc: fredriks@mcs.com Reply-To: joerg_wunsch@uriah.heep.sax.de (Joerg Wunsch) In-Reply-To: <199605251730.KAA05048@freefall.freebsd.org> from Lars Fredriksen at "May 25, 96 10:30:03 am" X-Phone: +49-351-2012 669 X-PGP-Fingerprint: DC 47 E6 E4 FF A6 E9 8F 93 21 E0 7D F9 12 D6 4E X-Mailer: ELM [version 2.4ME+ PL17 (25)] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-freebsd-scsi@freebsd.org X-Loop: FreeBSD.org Precedence: bulk (Moved to freebsd-scsi) As Lars Fredriksen wrote: > Here are the context diffs.

I don't particularly like the #ifdef EXB_8500C -- either we do support it, so it should be available all the time, or we don't. But the other thing (and that's why the freebsd-scsi) is that it wasn't clear that the entire conception of ``MAX_DENSITY_CODE'' seems to make sense. What are the pros and cons? Why is it there? Is it only ``legacy code''? -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) From owner-freebsd-scsi Sat May 25 15:20:29 1996 Return-Path: owner-freebsd-scsi Received: (from root@localhost) by freefall.freebsd.org (8.7.5/8.7.3) id PAA17377 for freebsd-scsi-outgoing; Sat, 25 May 1996 15:20:29 -0700 (PDT) Received: from linux4nn.gn.iaf.nl (root@linux4nn.gn.iaf.nl [193.67.144.34]) by freefall.freebsd.org (8.7.5/8.7.3) with SMTP id PAA17372 for ; Sat, 25 May 1996 15:20:26 -0700 (PDT) Received: from uni4nn.iaf.nl (root@uni4nn.iaf.nl [193.67.144.33]) by linux4nn.gn.iaf.nl (8.6.9/8.6.9) with SMTP id AAA00491; Sun, 26 May 1996 00:20:11 +0200 Received: by uni4nn.iaf.nl with UUCP id AA04253 (5.67b/IDA-1.5); Sun, 26 May 1996 00:19:31 +0200 Received: by iafnl.es.iaf.nl with UUCP id AA18114 (5.67b/IDA-1.5); Sat, 25 May 1996 23:33:01 +0200 Received: (from wilko@localhost) by yedi.iaf.nl (8.6.12/8.6.6) id UAA03638; Sat, 25 May 1996 20:45:35 +0200 From: Wilko Bulte Message-Id: <199605251845.UAA03638@yedi.iaf.nl> X-Organisation: Private FreeBSD site - Arnhem - The Netherlands Subject: Re: How to send "start unit" to disk during boot?

Hmm, I think DEC did this from Day-1 when CD-R was a unheard of device.

The thing is I _never_ saw it on my tape units (I have a couple, you probably saw the list on -scsi go by). So, I'm wondering if it is really a sw bug or it is a device-specific FreeBSD interaction. I've seen far too much strange errors coming from crappy firmware in devices. > Untli this bug is fixed somewhere in kernel land I had the idea to > disallow blocksizes >64 blocks in dump ... I think people wouldn't find > it funny, if they are unable to restore their backups in case they > saved the time of verifying a dump ;-)) I agree a readable dump is strongly preferable :^) This gets back to my question posted sometime ago: how does one verify a dump??? That is, without actually restoring it.. Correct me if I'm wrong but I did not see any options to do this. (Of course you need a _really_ quiescent filesystem to make this work) If a more or less painless 'compare' is feasible, I can try to do some testing with the various tapehardware. I can borrow I think some 10 types of different tape units from my boss (QIC, Exabyte, DAT, DLT). > Don't ask me, what's exactly the reason for this ... Was this broken > in 1.1.5.1, too ???
