Default M4100 Drive Trays

Hi folks, Great forums, lots of good info…

I was wondering if anyone had a source for M4100 drive trays? I just got my hands on two M4100’s that have no drives or trays in them. I purchased 8 Seagate 160GB IDE drives and now only lack the trays to put it all together.

If someone has a picture of one they can post I can easily make my own.

Thanks, Dean

NorthwestTechnical carries some parts, but did not have any listing for the 4100 sleds. They had 4000, but they are different. If you have one you may see if they are interchangable. Since Adaptec has discontiuned this model now, they will likely sell of their inventory. They did this with the other models.

If you are NOT going to moving the 4100 around you can have them lay loose. Or at least install some screws to elevate the drives for better cooling.

Or search eBay for them. Someone may have a failed unit they are parting out.

You can also use nylon standoffs between the case and drives and mount the drives directly to the case. I would snap a picture of the 4100 sled, but mine is up and running being used.

Very Cool! Thanks for all the responses and especially the photos.

That will make it very easy to duplicate the trays in my shop!

Anyone else that may need trays can contact me.

Thanks Again, Dean

Okay all,

I have been looking at this drive tray and it looks to be made of steel. I am thinking that if these trays were made from aluminum they would dissipate heat faster and much more efficiently. Any thoughts or comments.

Thanks

I'm not sure alum would work any better. Two things, There isn't really that much surface area. and if you notice the slight upward bend in the end with the slots. It is meant to spring slightly to keep the drives tight (no vibration).

I guess the question to ask then is heat a problem in these servers?

I could always double or triple the number of fins, thats not a problem.

Oh, going off topic, what type of memory cards do these 4100 use?

Thanks for the input.

No thermal advantage since most all of the drive is exposed. The sloted ends mates up to the ear sticking up on the chassis. Mine has some sound deadning material on the chassis, I think. Don't believe it's on the sleds. Where the locking nut is for the sled.

Making it out of al would work, but... would bend real easy. I would use steel, if you have it. Now these are not removed very often. Unless you use it as a test machine like mine. The steel looks to be ~16ga.

I have never heard of anyone having heat problems with the 4100. (somebody please correct me if I am wrong) newer drives are more quiet and cooler compared to older drives. These units are only running pII 233mhz. They don't generate alot of heat. The 4100 is a good machine. I am still hoping someone figures out how to get large drives into these units. Memory is 256 low density pc-100 sdram.

Hmmm ....

Good points, had not thought of the durability aspect of it. The aluminum would tend to give up much faster than the steel, especially if installed and removed frequently.

Okay, Steel it is, time to get into my shop!

Thanks for the tip on the memory!
