PrimoCache Overview
Sorta like windows storage spaces pools, sorta ZFS-ish

Alluxio – A Memory-Centric Virtual Distributed Storage System
It sounds sorta like they implented a distributed cache/storage broker, where the local node runs something similar to ZFS/ZIL/L2ARC, with final external persistent storage tier connected as a plugin.

Justifying FS-Cache []
FS-Cache seems to have been merged into the 2.6.30 kernel so is available for NFS systems. Somebody ought to make a nice little VMware VM appliance to grab local RDM SSD's for FS-Cache to grab external NFS shares, then refeed that to the VMware host server as a local NFS datastore. Though that Marvel Dragonfly hardware accelerator which links directly into VMware drivers is probably faster (though less generic).

facebook/flashcache - GitHub
Based on dm-cache and in production at Facebook. Bcache is architecturally superior but less mature. Kernel module for SSD caching of IO

Bcache - BcacheWiki
Interesting work on a filesystem agnostic block device cache implementation using SSD's, as a linux kernel patch. Very similar to ZFS' L2ARC cache which is also intended for use with SSD's. But the big difference is that this is a read/write cache, so technically it is a hybrid of ZIL and L2ARC. Creator works for Google, so this might have legs...

Marvell Launches New DragonFly Virtual Storage Accelerator [SNW Spring 2011] |
This appears at first glance to be a server local caching card that uses local SSD's, with drivers that hook into the hypervisor's network storage drivers (probably iSCSI, maybe NFS) as a transparent network storage caching layer local to a hypervisor, reducing network IO. Which is an interesting way towards boosting speed, since many VM servers using network storage have idle/empty storage slots onboard.

hashcache.pdf (application/pdf Object)
This hurts my head because, in a way, this is so simple and awesome. Use a specialized/tweaked hashing algorithm to generate the actual hard disk location of the cached webpage (hash the URL into a filepath for example). Skips the index lookup stage so obviates the need for a web cache index. I wonder if you can do filesystem tricks like altering the create time to match the web server's file age response, so that doing a cache file age check is a compare.
