Official IRC Channel - #reddit-sysadmin on Official Discord - •. Are any of you using RAID controllers (PERC or LSI, not sure if there are others) with CacheCade functionality enabled? I'm planning quite a bit ahead here, like a year, so by then it may be all change, but a server with a good spinning RAID array, plus 512gb or so of CacheCade SSD Cache on the RAID controller, running some form of VSA would appear to be a way to get some serious performance that is 100% vendor supported (hardware and VSA software) for not a lot of money vs. What NetApp or EMC or someone else would charge you a lot of money for. The keys are oem-specific - you can cross flash models - but they may not flash back. Making an ibm card into an h700 will not give it cachecade.

The oem keys are tied to the oem board which is not reflash-able. I think the software versions have a demo - not all controllers get cachecade 2.0. Some are stuck on 1.0 forever (esp lsi rebranded).

If you do use cachecade - use a DDR3 ram based model - or pci-e 3.0 - otherwise you will choke the controller with a 512gb of SSD and hard drive. Intel makes a few variants that are pretty cool - they tend to take care of their firmware more than LSI. There are about 200 variants that run cachecade 1.0 to 2 out there - be careful what you buy!

H700 with 1GB Nv cache has an encryption key on the cache board to enable cachecade 1. Packard Bell Easynote Recovery Cd Download. 0 (read-only) - sucks. 9260-8i - buggy as hell - sorry folks - probably why i hate dell systems compared to hp.

LSI and dell use reference designs (P.ray E.very R.ebuild C.ompletes) - PATROL scan and rebuilds are super sketch compared to hp (which used to use LSI chips but now use adaptec pmc-sierra). 9260-8i - $300 on ebay cachecade key - $250 Battery (a must) $179 IBM M5015 - $250 with battery - key (can't use lsi one) - $300 for cachecade 9260 series can't do raid-5 all the way - you want the dual core 9266/9285 series - they are hella faster.

These are pci-e 2.0 - the new 3.0 models aren't out yet. They run so damn hot - and crash when overheating - that you need to seriously look at your ducting/ventilation - not friendly to warner temp datacenter/closets. The new LSI nytro series are similar but incorporate up to 1TB of flash on board and can do iscsi caching. LSI sells the fusion i/o software that runs on both the host/guest to offload to fusion i/o (and nytro) - this is the best performance you'll get period. Cachecade 2.0 is not available on all models - especially non-lsi oem-branded - it's a clusterfffffuck. I implore you to wait for better solutions - for the few that have tried it - it doesn't work so hot on vmware - which is why they make a product that runs in both the guest and host - without the guest module performance is subpar.

The bottleneck is the sum of the SSD drives - say if you have 4 drives for cachecade in raid-10 - the real hard drives will never peak above the speed of the cachecade drives. A birdy told me hp is going to release this for their new gen8 - they are going to tie your server to their autonomy cloud to auto-tune systems based on results of ten's of thousands of systems - slick use of that $10B purchase. I decided @ 1/gb for samsung slc drives (small ones) it's cheaper to just throw a bunch in a jbod and configure the apps to use the disk i/o themselves. Tl;dr: cachecade sucks as-is with vmware - mostly because the controller is pretty flakey and so are the drivers. Want to buy my 9260-8i:) • • • •. So, I realize this post is a month old but I just installed two Intel 520 series 120GB SSD drives in a Dell R510 with the H700 (1GB cache) controller. Rebooted, went to raid config and added cachecade disk, selected both my SSD drives (yes you can use non dell branded!) and confirmed drive was created successfully.

If I look in ESXi 4.1 client under hardware status I see the cachecade drive. It's only been running about 24 hours, but best I can tell things on this particular host are a bit snappier but I don't have any real solid numbers yet.

This host has a fileserver, my vcenter server, and exchange2010, and a SQL server running on it, but only the first 3 are using local storage and would take advantage of cachecade. I should have benchmarked server before hand, but I'll give you a seat of the pants kind of benchmark results in a few days. Yeah I've figured out that running the drives in jbod is the best (for life) or raid-0 if you don't mind write amplification. (or cachecade). Picked up a cachecade 1 chip for 50 bones (everything but write). The ibm m5014 cachecade+everything else was hella expensive but they throw in snapshots and other crazy stuff.

LSI card from HP $60 Cachecade 1 chip $50 M5014 with LIPO BBU08 $129 M5000 Performance Key $329 (ouch) [9265 without Fastpath is just as fast as M5014, double ouch] 9265 can't do more than 4 ssd without killing the SSD bus - triple ouch. Brand new PCI-E 3.0 CV models with CC 2.0 Pro are $1530 (same as LSI Nytro 100 which is cachecade built in 100gb slc) • • • • •.
