Seeking Guardian OS Limits

[blue68f100]

As the topic reads.

We are seeing more and more Guardian OS units come through this forum. I am seeking data on the upgradeability of the GUARDIAN OS.

We have run into limits that I suspect is SnapOS limits, 1T. Will not debate weather it is hardware or software based. Mute point it is a limit.

The 4400 were only made with 480-720 gig. 160w PS, 1-1.26 P3 w/512meg ram, 2 1gb lan ports, Ultra160 SCSI on 720 model for backup.

Is this a Hardware LIMIT or just the maximum size hard drive that was installed due to cost and size when these were built?

The 4200 has a std lower capacity of 320-640gig, hot swapable. 2.4ghz Celeron w/256meg DDR (3 slots expandable to 3 GB), 250w PS, 2 1gb lan ports, opt Ulta2 SCSI, iSCSI support.

The 4500 has 1-1.6T, iSCSI, 2.4-3.0ghz P4, 3 ddr slots 512m-3gb, hot swappable, 2-1gb lan ports, 250w PS, Ulta2 SCSI, expandable with ext storage arrays

NOTE: All of these units seam to be limited in size by the Largest drive produced when it was design.

Are we seeing the limit of a 4 disk Array?

Or is this a limit of OS, Snap OS = 1T, Guardian OS 13.6T (4500 w/exp) ?

Does anyone know what Linux Kernel this OS was built on?

Open for facts gathering

For those wondering what a oss file is. http://oss.snapappliance.com/ Does the GPL license mean any thing? Yes,This is because the use of public code. So they are required by the agreement to release the code.

Give you the license to modify the original sources

Did some more digging. It looks that only the 4500 is listed with storage above 1T (1.6T). Most all other stop at 720gig. I then went back through my records where I worked with a user tring to upgrade a 4400. What was discovered was the drives would reconize large disk but disk format was limitted, prior till building the raid.

Here are some details to get you thinking. OS v 2.6 BIOS ????.

Org 160gig Maxtors 4G160J8 formated to 154,476 gig (RAID5) cap.
200gig WD2000JB-00 formated to 169,7700 gig (RAID5) cap.
200gig Maxtor 6L200P0 formated to 154,476 gig (RAID5) cap.
The 160 gig maxtor had as much usable space as the 200gig Maxtor
All of the 4 disk array raid5 sets were roughly the capacty of 3 x formated space
With the 200gig maxtor giving away 45gig to the 160 gig.

So it apears there is some issues with Large drives on Guardian OS units, too. All execpt 1 (4500) will accept 400gig drives.

Sam, I confirmed what you found on the kernel.

You reckon i should wiki table it the data from the Kernel's?

I don't recon that will hurt, don't see what advantage it will gain. If you do just put a foot note under the Guardian OS Snap Units.

I have been looking over the "gsu" OS files. These have more reference to different hardware than the Snap OS. There is reference to platform byte, CPU type, speed, ram, scsi, HD cap, ....

What will these upgrade to?

Besides the mega speed boost, it apears these may have limitation too.
