My company is looking at using Nexenta as the foundation of the storage stack of a public cloud solution. Therefore, we will definitely be implementing dedupe as will be thin-provisioning all VMs and over-subscribing the storage we have. FYI, we are going to have dual head nodes for each storage...

Thanks everyone for your replies. We're exploring vBlock, VSPEX and FlexPod as well as full homebrew SuperMicro compute/storage setup and Cisco UCS compute + SuperMicro storage options through a VAR. I'm currently leaning towards the last option and we should be able to get under the $1M for...

Thanks for that info :) It's a really relevant and on-topic response that is actually useful.

Does anyone have any experience with Eucalyptus, OpenStack, some of the other SmartOS applications/overalys? Especially in comparison to vCloud?

Thanks for that info, I'll definitely look into it. That said, we do have experience with VMware and a partiality to it and the others of the big 3.

I've been working with the sales team on stuff and they've been great so far. Then again, I'm looking at buy $110,000+ of licensing :p

Any further more specific thoughts? Especially on vCloud as that's what I really want to know/learn about? Thanks :)

Thanks for that feedback. There's pros and cons to "it" (with it being 'enterprise hardware'). Really, with cloud stuff, economical commodity hardware is part of the pluses with redundancy, "lots of it" and SPLA'd software holding it all together to keep everything as affordable as possible...

Thanks for being a dick. This is the sort of reply I absolutely wanted when coming to HF for SOME INITIAL THOUGHTS BEFORE FOR PRELIM COSTING BEFORE I BROUGHT IN EXPERTS COSTING ME BIG $$$. From an individual curiousity, I'm interested in how to build a vCloud setup as much as I am from a...

Yes, we'll be looking at bringing an expert in, but before I start dishing out $ to get advice, I need to have a basic plan I can cost to assess viability and present to our minority-share partner. I'll put that SAN on the list to check out. I'm partial to ZFS, and I'm pretty sure I can get the...

My company has been providing SaaS to clients for some time now with us receiving HaaS & on-demand storage from our data centre and then slapping on vSphere and the required software for the client etc. etc. Now, we're looking at doing a JV deal with another partner that's been doing a...

Seagate GoFlex Desk drives are great. I have 7 and another 10 are on the way. Very happy. The 3TB model is what I have and they actually are Barracuda XTs inside so go like a rocket (I'm talking 200MB/s transfers).

You rip the drive out and use it as an internal, duh! :p

I'm pulling 3TB Seagate GoFlex ones from the US posted to me on Australia for an average of $200. I've bought 14 and will get 6 more.

I read that the OP has 2 x 1TB drives and wants to buy 2 more and have 4 in his NAS Enclosure and do RAID10. Easy done as long as it supports that level of RAID. Am I missing something?

If I said that then you might buy up the ones I want :p Haha! STAC3000102...check it out :)

Create a small RAM drive and set a small cache on that? :D

I'm currently buying up Seagate GoFlex 3TBs for between $150-$230 to rip out the Barracuda XT inside. I've bought 8 and am going to get 20 in all. Make 4 x 4 drive RAID-Z2 with 2 hot spares and keep 2 as external drives to backup important data. When the prices come down I'll stock up on 24 3TB...

They sure are! You know what else is huge...

I read this whole thread and LOL'd. A lot. :D

I'm pretty sure you can use imagex to capture the drive as WIM. Then there is a tool to convert the WIM to a VHD. Once you've got that VHD you just need to convert it to VMDK and you're good to go.

Due to cost restrictions we'll be starting with 1 or 2 servers and then adding more. The intention is to eventually have a pair of servers which will act as head nodes purely for the storage system, but this will only happen once there are enough other servers to handle the load of the VMs. So...

Well I certainly underestimated how much of a dick you are. Sorry about that, won't happen again. You missed a keyword: "initially". I don't mind if there is some underutilization of my L2ARC in the beginning as once I shift VMs to new servers there will be more free RAM and everything will be...

Agreed. It's not too difficult nor expensive to buy some portable 2.5" 1TB external drives for backup. Have a group of drives on-site and off-site and rotate periodically once backed up.

I'm not looking for cheap, I'm just not looking to spend an insane amount of dollars for overkill or be wasteful. I can't afford to have 2/3 of my disks set aside for parity. I'm probably going to go with what I originally suggested which is 4 drive RAID-Z2 vdevs (2 data + 2 parity). It...

Well then why would you even bother posting? Just to be annoying? IIRC primary school maths 10 x 3 = 30 ;) But, yes, I would do this if I could afford to have that much redundancy but I'm not willing to have less than 50% of my drives being data...just too much $. That would mean 8 (data) +...

You sound like #occupy. We are the 99% and shizz. LOL.

The amount of data, initially will be about 5TB and expected to grow by a minimum of 200GB/month. The data is comprised of active/running important VMs, testing/dev VMs, general business data and non-critical media (music & videos). The most important data will be backed up online and the...

RAID-Z3 would mean 7 drive vdevs which starts to significantly reduce the number of vdevs involved in the overall stripe. Over 45 drives it would mean a stripe across 6 vdevs plus 3 hotspares.

Thanks for the replies. I'll add a few more details as the discussion has gone a little off-course. The plan is... The drives are in a 45 drive chassis (JBOD) with dual expanders for both backplanes. Each pair of expanders are hooked up to a head (i.e. dual heads) which are set up as a primary...

I'm concerned about using a set of striped mirrors with ZFS for my data--I will likely have 33 drives use. I could set this up as a stripe of 16 mirrors with a hot-spare. Sounds good, but if I lose a single drive, that mirror is compromise and has no redundancy during the rebuild. This...

There already is a NAND Flash shortage...

Hmm?

Don't replace the CPU with an old one, just get a different mobo and keep the E3 :)

I'm an N+2 person as you can lose 1 of something and still have redundancy...i.e. go with RAID-Z2!

Doing a bit of research, it seems like these 'Expansion' drives contain Barracuda LPs :( I'm hoping that's not true and someone can confirm? :D

I LOL'd at your title: "I have issues" hahaha Are you able to access the drives at all in Windows? If so, can you read/write fine? Have you tried physically disconnecting all of your drives other than your OS drive to see if this makes a difference? If not, give that a show and try each one...

Can anyone confirm whether the Seagate Expansion external drives contain Barracuda XTs like the GoFlex Desktops? I'm looking at: Seagate Expansion 2TB...

Don't need/want TLER with ZFS :D

Both: business and personal. I'll have 4 x 6 drive RAID-Z2 + 2 hot spares for 48TB usable space.
