A question about Server rails

Recommended Posts

Posted · Original PosterOP

Hello lads, Despite knowing nothing about servers besides a FreeNAS system in a corner, I bought a Lenovo Thinkserver RD640. And it's been leaning up against a wall for the last week. I want to mount it in a rack but the first set of universal rails I bought on eBay didn't work (did get a refund though!) Since I've now learned by trial by fire, How are rails categorized? Do all brands have their own mounting hardware? The only listing I can find that specifically mentions my machine is almost $100. Would RD540 rails work as a substitute?

 

This is a pic of the first set next of rails to my machine. I have no idea what I'm doing. I got it for a good deal and I'm only using it for Minecraft and FreeNAS.

Otherwise, there are generic rails that hold the server from the bottom

Well I tried to be fancy and go with proper sliding rails, But my wallet is telling me generic bottom supporting rails are the way to go.

 

I get that this isn't consumer grade hardware, But why the fricc are 4 2.5 foot long strips of metal going for over $100 used. I swear this whole industry is nothing but a proprietary cash grab.

Well, cabinet drawer rails rated at similar weight and length cost about as much. 

Pretty cheap if they only pull out half way and don't hold a lot of weight. 

Something that extends all the way and supports what a fully loaded server might weigh are pretty expensive. 

 

Quick check of home depot site looks $100-150 for ones long enough and strong enough. Checking server rail prices at supermicro, actually look less expensive then ones for kitchen cabinets.

Prices of used bare rackmount chassis are even worse, often you can buy an entire working server for less.

Looks like no sliding server rails was a blessing in disguise, my unit barely fits in my rack. Didn't even think to measure it first. Either way, glad it worked out in the end.
