ramdisk A ramdisk question

[Nixoriuz]

Is there a ramdisk os that saves to a file on a HDD/SSD on shutdown and loaded the file back in ram on startup from the HDD/SSD, no i don't want to use softperfect RAM disk or something similar. i got a server with 112GB ram and i'm not useing all of it and it would be nice to have something like this.

What OS?

 

If you on linux, you can script tmpfs to do this(built into the kernel)

 

You don't need a ram disk. The OS will automatically cache all the files that are used often and cache disk writes.

since he mentioned server with 112GB ram, i'm guessing this is for a specific use case where ramdisk could have big advantages.

Totaly depends on what your doing. 

 

 

Hey OP what are you using this for?

 

It won't really help for file servers over gig networking.

 

I wouldn't use it as a vm boot vomume.

 

If you care about your data, then id make sure you have dual psu's, dual ups's, and a ecc, a perferbly a heartbeat clone.

This is more like a test to see what i can do with a Ramdisk and how far i can push it and since i'm using VMware i'd like to have a Ramdisk OS 

Data-loss is not rly that important

 

Since i don't have an SSD or any form of fast storage i'd like to use a Ramdisk  

 

The system i got under my bed is a HP Proliant DL160 G6 dual xeon running esxi.(Don't remember the specs, server is also off atm)

If you running esxi, you can't make a ram disk. Its not supported in that OS.

 

If you want ramdisk, id use linux and kvm(if you want easy management you can use ovirt.)
