Snap4000 Com1 port

[bitor]

What is the Com1 port on Snap4000 motherboard? Can I hook a com connector up to it and hack it? Can I maybe telnet via this com1 port?

Side note:
Less post from ppl because of the nice weather. Has anybody noticed? I have.

[re3dyb0y]

I think there may be/are the pin headers...

It will be on the forums somewhere


Also, i'll get back to your PM when i get a chance!

Phoenix32 was looking at that. The 2000v1 also has it. I was informed by a snap tech that it was disabled to free up resources. But to my knowledge no one has tested to see if its actually dead. Use a Null Modem cable and Hyterminal to capture the data. If you get anything you may need to play with the port settings to mkae it readable.

I knew someone was going to ask this some day.

Yes, yuo can telnet witht he SNAP 4000 via that serial port. Basically, what you end up with is something similar to being in the debug menu.

Dead on the 2000 or on some 4000, may be, don't know. I just know I used hyperterminal and connected to my SNAP 4000 no problem...

[bitor]

Thanks for the information!

Interesting... Why would the company put in a redundent way to do the same thing as you would via a web browser. There must be something that is special about this com1 port other then being just another way to get to the debug. Maybe something extra. Say it not only does debug , but it might do other things that we have not found out yet. Just a thought.
I'm going to try and hook the com1 port up to my pc and see how it goes.

Thanks again,

Normally when you have com port access it give you access to the core files, like a backdoor. I've used com ports in the past to download firmware. On the Guardian OS, you have a com port used to diag boot problems. You can also ssh in to the server. This is a way to gain access to the linux kernel. Just to name a few.

Hey David

Very interesting. I'd like to dig in to the com1 port , but I'd like to know what type of connector does the com1 port take inorder for it to fit in the com1 female socket on the snap4000's mobo?
On a side note...I know the Snap4000 has a 233mhz cpu. My question is will it take a faster cpu? What socket is it ? I think it is a socket 7 but cannot remember. Also, could it be possible to use a overdriver cpu on it? There I go again...lots of questions.

Thanks again,

Phoenix32 has one that came wired up. You will have to get that from him. My guess is that it is using the keyed 10 pin DIN plug. I went through my stock looking for one a while back and did not find one.

Yes it was a keyed 10 pin rs232...

No on the overdrive...

Why? Because even if you have an overdrive (which people want too much for when you find one), on a PC, you still need a BIOS flash to support that CPU (the micro code stuff). I have not seen one of those BIOS flashes around for a SNAP 4000/4100, have you? I seriously doubt the BIOS on these boards will support those AMD overdrives. It is possible, but I doubt it, and I am not spending $50 plus shipping to find out. Someone else had one around here, and we asked him to test it, but he never did, or at least didn't report back on it. FYI, the overdrives work on Super 7 (Socket seven with some enhancements, remember those days?). I am pretty sure the 4000/4100 is a basic socket 7. Try it if you want. It shoudn't hurt anything, well at least not to the SNAP board, it just probably won't work. It is possible it could hurt the overdrive if the voltages don't match.

Yes, I researched this since the original posts on the subject because nobody else seemed willing...

[bitor]

Hey

Thank you for your knowledge and research concerning these matters. I don't have an overdriver , but I recall Intel making one. The "Overdrivers" had a board that the cpu chip sat on. I don't think there was a need for any bios modifications on them. Just plug and chug because of the board. I cannot say about the AMD ones. My friend(yes I remember those days.) got an Intel one years ago. Wow, did it cost a lot of money($300). I do remember him having to reset some mobo jumpers for the bus thought. I still have a 386sx and have the first math co-processor put in a PC.(It's big and has gold all over it) . Anyway, do you know of a place where I could get a keyed 10 pin rs232 ?

Thanks again for you answering my questions.
Sincerely,
bitor

I thought the SnapOS was limited to 1TB. The Snap website says that the Snap12000 has a max of 3TB. How is this possible ?

You end up with 3 raid 5 arrays 1T each.

The fastest Intel CPU in the socket 7 Pentium class was the 233Mhz CPU, which is what we currently have. The overdrives you are talking about were for 386 and 486 systems.

Now with that said, Powerleap (evergreen) made a deal just like you are talking about. It isa CPU on a board and the board plugs into the socket. They use the AMD K6 CPU since they had higher speeds for those (Intel had gone Slot 1 and Pentium II by then). Now I read up on these overdrives, and it says right in their documentation that the BIOS had to support the micro codes for that CPU (a BIOS flash). They also had a very long list of BIOS flashes they had for various Motherboard to use this overdrive. Guess what? SNAPs were not listed. As I said before, if you want to try it, have at it. Just let us know how it went (and be prepared for the "I told you so", lol).

I have not bought a cable like that in a very long time. The last one I bought was at Radio Shack, but they don't carry as much of that stuff as they used to, so I don't know if they will have it or not. You could try places online like Jamco.

That -AND- those 12000 units have the Guardian OS...

The 12000 came in both SNAP OS and Guardian OS flavors. This may be the case with the 14000 also, but I think it was just Guardian OS.

right SNAP-TECH?

I googled and found this

Multiple File System Options

The Snap Server 12000 can be configured for enhanced performance or maximum file protection. Options include:

• RAID 5 (disk striping with parity): For each array, the size of one disk is reserved for parity checking. With two arrays of six disks, yields 750GB usable capacity for the Snap Server 12000/960GB (factory default).
• RAID 1 (disk mirroring): Second set of drives duplicates the first set for maximum data protection (50% usable capacity).
• RAID 0 (disk striping): Large, virtual drive with data striped across all drives of the array (maximum of eight drives per array). No loss in usable capacity.
• Individual Independent Disks: Twelve separate drives, each seen as a separate volume (JBOD).

Hey Andy:

I stand corrected. I do remember that now. And I do remember evergreen. I think they went under. Well, I believe you Andy. I'm not going to try it after what you have posted. I am just provoking thought on the Snaps. And by the way I did a search for the Jamco site and I cannot find it. duh . Can you tell me what the website is. There are so many keywords with Jamco. I will check at Radio Shack, but I have noticed that they have reduced a lot of this type of stuff which makes me believe I will have to buy it on line somewhere.

Thanks again,

Hey David:

Wow, lots of good information...you know how I like information. So, If I have read this correctly, They do this(make 3TB) by using JBOD? Correct? Or did I miss something? I'd like to have the Snap12000 , but the price is way to hight for this poor boy. I know the SnapOS has some limitations , but you cannot beat the lack of virus you can catch with it. Do you think it is possible for somebody to read a Snap drive if they had a UnixOS ?

Thanks again,
Sincerely,
bitor

P.S. I have been backing up my media system(mp3 files) for two days on DVD+R 1-16x TDK. I purchased 100DVD sleeve at Costco and they are JUNK!!! I've used
51DVDs and out of that 24 are bad. I'm using them for data back up and have never had this bad of a problem before. I've had the best luck with HP DVD's. So stay away from them(Costco's TDK DVD's) if you can .

Bitor, It could be your burner, and not the dvd's. I've seen may burners try to burn at a rate that was not correct. Slow the burn speed down. And allow the dvd burner to cool off between burns. I've seen cd burner have the same problem. The ony one I have that I can burn 50 back to back is my Yamaha, which is not made any more. I generaly buy what's on sell at Micro Center, and I avoid Fry's GQ brand. I have gotten several batches of CD's from them rated at 52x, I was forced to burn at 12x. And to top it off that what the cd info said they were. Packaged at 52x.

A snap drive can not be read with any other os. It is a Highly MODIFIED BSD file system.

It seams to be a standard practice to size arrays (drives) by raw un-formated capacity. That is the way the HD mfg size them. The reason why is some file systems waste a lot of space. The Smart system reserves sectors for replacements. So it is very hard to say what a system will format at. Even BIOS settings have a impact.

[Phoenix32]

It could also be that he is correct. I have used TDK blanks (DVD-R x16) before with my burner (Plextor) and had no problems, but a TDK 100 pack (DVD-R x16) I got from costco last fall had the same problem he just said. 1/2 of them ended up as coasters. These were -R, not +R, but same thing from same place....

[bitor]

Question:

Why is it that the Snap4000's do not have a "shutdown" link via the browser? I have version of SnapOS 4.0.860. Strange. Maybe it's a hardware thing. I have tried the command and it says that it is not supported. I thought there might be a switch in the SnapOS that could turn this on. Really strange. Yeah, those TDK's are junk I believe since you had the problem too that makes it more possible.

Thanks again,
Sincerely,
bitor

Question:

This is based on the Snap12000 with JBOD.
Is it possible , provided that the power supply will handle it, for a Snap4000 to have 4 x 500GB hard drives installed with a setting of JBOD ? Ofcource, the Snap12000 is based on 12 x 250GB in JBOD configuration. Since we know that the snapos cannot handle over 1-1.2TB and with that being said and it in the settings of JBOD. Maybe as long as the snapOS sees it as less then 1TB per IDE with the settings of JBOD then It might be possible?

P.S. Why is there a lack of SnapExtension programs? What gives? Seems like a wealth of untapped potential

Just a thought,
bitor

[Phoenix32]

Bitor, The 4000 does not support a remote shutdown, this is why it is not in the menu. You can do the command via the debug menu and it will tell you it is shutting down, but it will not actually shut down no matter how long you wait.

I have not tested it due to the $ involved, but I can see no reason why the 4000 would not support 4 x 750 GB drives as single drives (being on the same IDE channel should make no difference). Notice I called it single drives, I refuse to call it JBOD (even though that is what the documentation calls it also), because it is NOT JBOD. JBOD combines drives (even of different sizes) into one large disk (not striped either). JBOD = Just a Bunch Of Disks.

Anywise, it may not work, I have no idea without testing it myself, but from what I can tell from the hardware etc, it should work fine IF you replace the power supply to one that can support that load.

[bitor]

Hey Andy:

Yeah, me either due to the $ involved , but I'd like to try it when I maybe get the money(hope I win the lotto :0)) or whenever the price drops enough for me to afford it.
Yes , that is correct. I agree. Why would they call it JBOD? Must sound better for them to market to the company's/public/IT person. Strange It really isn't JBOD.
Yes, I know the Snap4000 doesn't support it via the menu. I was just wondering why it did not or if there was a undocumented command.
Does the Snap2000 or Snapp2200 support this command in the menu?

Do you know how to force JVM to run so I can invoke SnapExt on my Snap1000 I have. I just want to do this temporary to use S2S then remove it. I know it will be really really slow, but I don't mind.

Thanks again in advance,

2200 supports remote shut down, not sure on the 2000's.
