SNAP 4500/4200 Limits
Well, we beat SNAP OS limits with the 4100 and 4000 (as well as some 1x00 and 2x00 units) into the ground, so let's see what we can do with Guardian OS units. Or more specifically the SNAP 4500 and 4200 (and maybe 4400).
We know they came in 640, 720, 1000, and 1600 GB versions. We also know replacement drives/sleds can be purchased up to 400 GB. From this, we know a 4200 or 4500 can do 1.6TB then. But, can it do 2.0TB with 4 x 500 GB or 3.0TB with 4 x 750 GB drives? Is 4 x 400 GB the limit? Or, did Adaptec just stop at 400 GB with these units because they are no longer current? We -think- the newer v4 Guardian OS is based on Redhat Linux (I don't think we know this one for 100% sure yet do we). But, can we base limits on this? We do not know what was modified or left out when they wrote the Guardian OS. Thus, even if we knew for sure it was Redhat, does that really prove anything for our limits? It would be real easy to sit back and say, "Yup, sure looks like it will handle more". But given the cost of 4 x 500 GB or 4 x 750 GB drives, I don't know about you, but I don't have that kind of money to throw around for experimenting. Has anyone here tried more than 4 x 400 GB drives in a 4200 or 4500? (or even a 4400 maybe)? If so, what was the results please? Has anyone got a really good belief based on solid evidence that the 4200 or 4500 (or even 4400) will do more than 4 x 400 GB drives? If so, what is your evidence please? |

We do know that Adaptec is offering the newer models 520 with:

Re: SNAP 4500/4200 Limits
I hooded up a monitor and keyboard and was not locked. Did not try it through the com port. Might try the default password for the GuardianOS.
What Guardian OS version are you running? UPDATED Read Below Update: Your 4400 dump has the same info as mine, We Must be on the same OS version. Quote:

When the Guardian OS was first released on the 4400 the Snap Appliance Dudes told us that the Guardian OS was definitely based on Red Hat Linux for the advanced features that it offered like; better security and integration into windows and mixed environments, then it was poked and prodded into what it is today… From a REP; I heard later that they stopped saying this (the bit about Red Hat Linux) publicly when a guru or two started typing Linux commands into it and managed to really screw their Snap Servers up, the Guardian OS might take some of the commands but they never made up a manual on what not to type... :nono: I didn’t ever hear if there was a fix for this as it didn’t happen to any of my customers but as the OS is totally on the drives I would imagine it would not be that hard? :evilaugh: |
Re: SNAP 4500/4200 Limits
Has anyone tried drives larger than 4 x 400 GB in a SNAP 4200/4500 or 4400?
Might be a moot point for me. Seems Hitachi and Seagate are the only ones making IDE drives over 320 GB. The Hitachis have had very poor reviews (high failure rates and high heat). The Seagates have had good reviews, but I am not a fan of Seagate, so... But this info may still be useful to others... |
Re: SNAP 4500/4200 Limits
I think I asked this once before quite a while back, but I will ask again anywise...
Do any of you have drive sleds for the 4200/4500, or know where I can get some? I need 3 drive sleds for a 4500. Yes, I know you can buy replacement drives (with the sleds) from various sources, but $400 for a 250 GB drive is totally unreasonable. If you have any drives sleds, or know where I can get some, please leave me a PM here on the forum or send me an e-mail at phoenix32x@hotmail.com Thank you... |
Re: SNAP 4500/4200 Limits
Are the drive sleds from the 725n the same as the 4500?

Note: The sleds for the 4200/4500 are very slightly shorter than the 4400 sled. I think David and somone else (Sorry, I forget who now) posted some pictures of the 4500, 4400, and 715N drive sleds here somewhere a week or so ago. |
Re: SNAP 4500/4200 Limits
The 4500 are shorter, about 0.375" and has "U" to one side of the V slot.

David provided me with some pictures of some sleds. In both pictures, the sled on the top is the sled from a 715N (which we think is the same as the 4400) and the lower sled is from a 4500 (same as a 4200 also). I need the type in the lower picture. If you look close, there is a U shaped slot on the bottom side near the back of the 4500 sled.
Also, David looked up the sled of the 725N, in a digram type picture, and it appears it is the same (or similar) to the sleds used in the 4200/4500, but it is difficult to tell in a diagram type picture. eschw95458, do you have a 725N sled to compare to? And if they are the same, do you have or know where I can get some of these sleds? |

Re: SNAP 4500/4200 Limits
They sure do look a lot alike don't they...
But anywise, if anyone knows where I can get some drive sleds, please let me know... |

Re: SNAP 4500/4200 Limits
Come on im just kiddin. I thought about bidding on it but with out the ability to get sleds at a resonable price i passed.
On another note. Confirmed 4 750 gig drives in a 4400 looks like 2.04 TB Raid 5 Ill let eschw95458 fill you in on the rest |
Re: SNAP 4500/4200 Limits
I just picked up a 4400 yesterday with 4 180gb drives, would you guys care to share the details of the 4x 750gb upgrade?
I'm running an old 2.4.040 OS |
Re: SNAP 4500/4200 Limits
It's easy on a guardian unit. If yhe unit has not been reset back to factory settings do so. May want to look to see if he had any addon keys. or OS updates on the unit prior.
Break the raid5 array if built. Power down and remove all drives execpt #1 Power backup, hot swap a new drive into position 2. Powerup, once up hot swap the remaining hd, then build your new raid5. Done I took 5 hr to build the 4x400gig raid5 in my 4500 so 750's should be around 7 hrs. |

I've been looking for a Guardian OS 3 and 4 version to load before I upgrade but since the only snaps I've every owned were all 4000/4100 units I don't have any non Snap OS Sups. |
Re: SNAP 4500/4200 Limits
You need to record what that key is if you want it, do it any way just incase you change you mind. You can sync to your SnapOS with it. It is not included with the std load. It was replaced with another software package. If you pester Adaptec they may give you v2.6 which is required for AD support. Vista is only supported on v4.1 or 4.2

Re: SNAP 4500/4200 Limits
Phoenix32,
I cant believe that guy wouldnt take 700 for that snap 4500. Any way nice job whats your plan with 3 of these now? Im not allowed to buy any more servers until i finish upgrading all mine. |
Re: SNAP 4500/4200 Limits
He is spoiled with the speed of the 4500's, he will quickly retire/sell his SnapOS units.
