Look what's gone open source!

This is great news for Linux. EnhanceIO has been submitted to the Linux Kernel. This technology is based off of Facebook's Flashcache technology.
Too put it simply, this driver enables an SSD to cache any block device. Check it out on GitHub.

That looks great. Do we know how stable? Sounds like that could even cache iSCSI and NFS?

Looks pretty cool. Wonder how long it will take someone to port to Windows.

Is this supposed to look like a bad infomercial?

 

[Patrick]

I had a similar thought but was fairly impressed by that guy's presentation skill.

I guess it will kill any regular SSD with all that brute force writes for each read from array...

 

[mrkrad]

port it to esxi too

if you look at flash as an extension for ram, then just keep everything in ram all of the time!

 

[analog_]

bcache is similar project in linux.

 

[RimBlock]

Videos gone.

Sounds interesting for sure.

dm-cache anybody?
https://git.kernel.org/cgit/linux/k...t?id=c6b4fcbad044e6fffcc75bba160e720eb8d67d17

it is in kernel 3.9
LinuxChanges - Linux Kernel Newbies

and it seems to address problem

I guess it will kill any regular SSD with all that brute force writes for each read from array...

Migration throttling
--------------------

Migrating data between the origin and cache device uses bandwidth.
The user can set a throttle to prevent more than a certain amount of
migration occuring at any one time. Currently we're not taking any
account of normal io traffic going to the devices. More work needs
doing here to avoid migrating during those peak io moments.

For the time being, a message "migration_threshold <#sectors>"
can be used to set the maximum number of sectors being migrated,
the default being 204800 sectors (or 100MB).
