I wish we had the hardware and software to use the data port on the MB.

Re: Snap 705N/4100 lives and thrives!
 

Yeah, you and me both. I might have to pick up another 4100 just to mess with it. I am a little scared to take down my current box as I use it quite a bit...

Re: Snap 705N/4100 lives and thrives!
 

Under stand that.

I purchased an flashram/bio/... programmer with the optional TSOP40 to read my 2000 flashram. Then discovered their was 2, one in socket, other soldered in.

One of these days I'm going to try to repair with the parts I picked up. If that doesn't work, I'm going to un-solder the other chip and read it. Then merge the files.

Then the fun begains.

For some reason I'm always busy. I think it because I'm so slow, due to my back.

Re: Snap 705N/4100 lives and thrives!
 

This is from my 4000 with OS 3.4.805, hope it helps...

Re: Snap 705N/4100 lives and thrives!
 

My 2200 with 4.0.860 has more cmds than than the 4000 with 805. So there nothing there to help us.

Re: Snap 705N/4100 lives and thrives!
 

When I install the 4.0860, I bet it changes to more like what you have. I will send you a copy when I do the update. I have the OS, just not installed yet. No need until a little later on (for the MS AD), so why use it yet?

Re: Snap 705N/4100 lives and thrives!
 

No there is no reason

And it will only hog more memory

Re: Snap 705N/4100 lives and thrives!
 

Exactly! ;)

Re: Snap 705N/4100 lives and thrives!
 

Hi, I have an interesting problem, which maybe someone can shed some light on.

I have used both 4100 and 705N servers.

I have found the 4100 to be very relaible but I have had two 705N which appear to mess up the Raid 5 array from time to time

This generally happens when copying large numbers of (small) files from one place to another ie for mirroring or backup ..... I keep a large number of files spread across a few 4100 / 705n / 1100 servers in raid 5 where possible.

The problem is not catastophic as I can generally rebuild the raid, but this put the server off-line for some while and is annoying.

I have just loaded the latest troublsome 705 with 4 160Gb drives and all appeared to be fine , I then started to mirror another server and after about half an hour .......... Uggg

Both were running the 3.4.xx series SW (being the latest that can easily be obtained)

I assume the only real difference between the OSs is cosmetic, so Any ideas wht the Dells should appear to be more troublesome.

There a very large number of Incorrect Block Counts I've only pasted a few here for example.

The error log follows (in reverse chronological order):

These can be good or bad. Think postive here.

Stacks are generaly memory related, which can lead to disk corruption.
I would open the unit up and re-seat every thing, ram, ide cables, cpu ... This will cleanup all of the connections. While you have it open make sure your fans are working.

Are you running any extra demons, JVS ...
How much ram in in the unit? If you are running low on ram it cause problems too. And for some strange reason as the HD capacity goes up they like more ram.

V3 OS supports MS AD 2k but not 2k3.
4100 do not support LBA48bit addressing as you proably allready know.

These are not very fast units (as with most snaps), I'm also wondering if you may be having some network (packet) lost/collision. As networks get faster these old units can't keep up.

Just a thought.

Re: Snap 705N/4100 lives and thrives!
 

Thanks, Actually I found a loose Ram chip (although I have had it happen on other servers)

RAM Size is 64Mb (old drives were 4x30Gb) now 4x160Gb so could be an issue.

I think my reliable servers have 128MB (but can't easily check as hidden in a remote place !!! - unless I can check through debug)

I installed a clean copy of 3.4.780 with no extras (the server had been PW'd and could not get access to it, so was the only way !!!) (Adapted just gave me access to 3.4.807 !!!)

If anyone wants it, it's here:



You say not very fast - I can get combined throughputs (ie multiple transferes)very close to 10MB/sec - I find the tranfer rate is limited by Windows not the Server, which usually puts a limit of around either 3.5Mb or 5.8Mb - no idea why (does not seem to be related to PC's CPU speed).

The 1000 / 1100 / 2200 etc series do appear to limit at app 1.6MB/sec.

Anyone know what type of RAM chips these take as Will upgrade to 128MB or more if desireable ??

LBA limit yes I know this, but going from 4x120 to 4x160 gave a worthwhile extra >40GB of storage (Raid 5)

(I did try 4x250 before I learned of the limit .... costly mistake !!!)

Re: Snap 705N/4100 lives and thrives!
 

There is a reset procedure to clear the admin password. Do you need a copy of the admin manual and reset procedures?

What is special about 3.4.807 compaired to 805 did they say?

12.5 Meg/sec is the max for 100mbps over IP. The RAID 5 will generally max it out.

These unit use DIMM's chip PC66/100, I think some users said they needed the low profile. Issue "debug memory" from debug to get full detail on installed ram.

The over size drives should not cause any problem.

Your example is a home built NAS/serverpc running RAID 0, and SNMP is having a problem too. I would edit that post and clean it out, it really doesn't apply to the snaps.

Re: Snap 705N/4100 lives and thrives!
 

Correct. Standard height DIMM's will work, but you can't get the cover back on :D

Re: Snap 705N/4100 lives and thrives!
 

Yeah, the 4100's will max out a 100Mb connection if they are in RAID 5 config. Not too shabby for NAS. I wish there was a way to upgrade these to Gb ethernet. The 4100's would REALLY scream then!

Re: Snap 705N/4100 lives and thrives!
 

The info regarding clearing the PW would be useful (although I just reinstalled the OS

Especially as I had no idea in what condition the server was .... it looked like someone may have "made some fixes to it" So to be safe, start with something I know.

Memory, I fitted PC133 / 128Mb dimms and have been thrashing it most of the day (3 PCs copying files to it to max it out ) .... So far it is behaving well and it will not get this kind of activity undernormal use.

Never seen 12.5M/s but just under 10M/s -

Actually I find that Windows appear to put a limit in TCP/IP transferes of 4.00M/s .... but can't find anything useful on this, all of my PCs (different models and CPUs all seem to Max out at the same speed ..... very odd and why ?? (and the reason to use 3 PCs to max out the server)

No idea what is special with 3.4.807 infact I wasn't able to DL it so will ask again when I have some time - but won't be soon as "I'm on the road again" next week.

I've removed the posting as you suggest, I just put it there incase it rang any bells as the symptoms seems very similar.

Thanks for the suggestions

Re: Snap 705N/4100 lives and thrives!
 

Reset instructions can be found here: http://wiki.procooling.com/index.php/Snap_Server_Resets

PC133 will work just fine, as you have stated, it will just run at PC66 speeds.

I might suggest that you look at the switch that you are using, as I suspect that it is the source of your 4MB/sec problem. I can get 10MB/sec or better on any one of the comps on my network, so I don't believe that Windows is your problem, unless someone has done some strange registry editing. It's possible that it could also be your network cards, if all of the PC's on your network have the same NIC cards in them.

Re: Snap 705N/4100 lives and thrives!
 

Hi Thanks for the link

I am primarily using Alied Telesyn 10/100 Switches, (and others) but I have tried others with the same result (Admittedly, due to the structure of my (ad hock) network data may have to pass through 2 or three switches, but none of this seems to make any real difference even through just one switch same result. I did spent some time on this with the same thoughts in mind but did not get anywhere useful. These switched can combile 3 or 4 PCs to one destination and can pass a combined speed of 100Mb/s.

I have a variety of network cards, again no difference.

The PC software, on all, is bog standard XP pro. ( A couple have win2k, but these are older slower PCS (celeron 700mhz based HP E-pcs) so I don't expect miracles)

Thankd again

Re: Snap 705N/4100 lives and thrives!
 

No problem, always glad to be of service.

Hmmm...again, this is realy odd. Mine passes over 10MB/sec to any ONE computer on my network. If you can, pull up the network config on your snap and post it. Not just the IP address and whatnot, but the full config that shows which network options are turned on or off. That may shed some light on this...

Re: Snap 705N/4100 lives and thrives!
 

When you have a router (Netgear FVS338) that has 92mbps through the WAN with a 266 mhz X-scale cpu with 16/32 meg of ram. It pretty much full speed ahead.

Yea, I had an old SMC that clamped me around 1.8 meg/s.

WRT following issue posted above

System 22/6/2006 7:57:24
F PANIC : blkfree: freeing free block

I though I was doing so well (after Mem upgrade) having copied >>200GB (500,000 files) to the server .... but then, stupidly perhaps, I decided to click on a compressed file residing on the server to open it and, Hey presto, it crashed again with exactly the same stack content.

Now its raid rebuild time again ............. :-((((((( DOH!

Re: Snap 705N/4100 lives and thrives!
 

500,000 files whow......:uhh:

Makes me wonder if your hitting a limit, I don't know about.

Re: Snap 705N/4100 lives and thrives!
 

I cant see there being a file limit

I know in some file browsers (one ive seen in Red Hat) it wont display files over a certain number....

Re: Snap 705N/4100 lives and thrives!
 

I suspect it may me a bad bit combo in the ram. Maybe he has an old pc laying around that has a DIMM's slot or two where he can setup mem86 to test ram for several days/weeks.

Did the ram chips have gold contacts or silver?

Wonder if these snaps support eec ?

I have a Unigen spec sheet from snap. Post the part no and I will see if its listed.

EEC is listed as an option.

Re: Snap 705N/4100 lives and thrives!
 

Hi, Answers

The ram chip was out of a very relaible PC been used for months at a time without crashes (so I think it is good, but I might just try your suggestion to be absolutely sure). Although it did exactly the same with a different Module (I upgrades from 64-128Mb).

Gold contacts (wouldn't uses anything else)

Server uses Non-EEC

Next step will be an OS upgrade when time permits.

Re: Snap 705N/4100 lives and thrives!
 

OS upgrade couldn't hurt at this point. I don't see anything in your config that would cause the speed limitation that you are having. I am really curious about it now! Any chance that you could hook a PC or laptop directly to the snap with a crossover cable and see what kind of speed you get?

Re: Snap 705N/4100 lives and thrives!
 

The speed thing

There was teh issues of MS limiting numbers of connections, which was becoming problems for peoepl trying to get faster internet

drTCP i believe you need to look at

Re: Snap 705N/4100 lives and thrives!
 

Damn good question. Wish I knew...

Re: Snap 705N/4100 lives and thrives!
 

I have the document on what ram (DIMMS) Snap Apppliance used. Could cross reference if I had some part numbers. You would think being a server they wouldn't take a chance with non eec. They did get a preimun for their hardware. Unless they did there own testing and screened them.


I know on my old fried cripid 2000:cry: , it was pretty pickey. I had like 12 ps of simm's laying around, only 2 in the lot would boot.
