I was just about to praise Isilon as well. I wish they would market better, because they have a fantastic product. You can linearly scale performance and capacity independently of one another, all without downtime. Their new nodes do 200MBps (bytes, not bits) of throughput *per node*. Flexible NFS load balancing, CIFS support out of the box, snapshots, synchronization, 10Gbit Infiniband backend network, 4 gigs of cache made globally available per-node... drool.

100k might not get you much SAN from Pillar...
I'd recommend checking out Compellent, too, but again, 100k is going to be a somewhat small SAN.

What?!? Please give your definition on "Small SAN"?
I've got a quote from Compellent on a clustered solution that pushed 170k for about 8TB raw.

Still seams high with clustering (assuming you mean 2 Mirrored SANs) and full SAS.

Nope. Clustered heads. To be completely fair, this might be close to list as I asked for ballpark pricing, so after discount it would've been somewhat cheaper, but still in that same ballpark. To add a set of tier 3 storage (750G disks, same aggregate capacity) would've added another 40k onto the cost.

Edit: this doesn't have Compellent, but it's interesting nonetheless:

The Pillar pricing is in line with the quote we got from them as well.

For example,
SLM 500-SAN SAN SLAMMER
SAN SLAMMER
$39,840
BRX 500-144F15J BRICK,144GB FC 15000RPM DRIVES,JBOD CONF
BRICK,144GB FC 15000RPM DRIVES,JBOD CONFIGURATION
$27,325

Now, if I remember correctly, a brick is 12 drives, so $30k there gets you 1.7TB.

You're at 70k for a 1.7TB SAN, and this is before support and software.

We added a bit more to our original quote, came up with just under 4TB of storage, a 2nd tier, as well as built-in NFS support from Pillar, and it was listing at almost 200k.

Yeap, the tier 3 was SATA, tier 1 was 15k FC.
We ended up with a MD3ki for a stopgap solution for VMware and Isilon for NAS. Prolly gonna go with a EqualLogic box to replace that MD3ki later this year.

The Compellent solution was really nice, and I'd recommend it to anyone who's got the cash.

Say you need 100TB of storage, nothing super fast or expensive, but easily expandable and preferably managed as a single unit. Think archival-type storage, with content added frequently, but retrieved much less frequently, especially as time goes on. What do you go for these days?

Hmm, interesting stuff, thanks for the comments. This was more for hypothetical stuff. Another group is on the cusp of picking up some EqualLogic gear (their big 48-drive nodes) for this purpose, but it just seemed like overkill given the task. Figured I'd lend a hand and see if there were alternatives for them, save the company some cash, at least assuming there were other alternatives to build-it-yourself solutions. I'll shop these around.

What's the scoop on Coraid, btw? I tried looking into them a few years back, but they didn't do demo units for some reason so I passed.

Yeah, I haven't been able to find any good data on them at all. The price is pretty awesome, and the concept makes sense, but I'm not going to take the plunge if they won't let me play with the boxes first...

At my previous gig, we had 2 Isilon clusters. Great product. Their replication product over a WAN wasn't great, but for regular day-to-day use, they were fast, reliable, super easy to scale, and well-supported (aside from some hiccups with the aforementioned synciq stuff). I will likely give them another go if I find an application for it.

For a base cluster of 3000i's with redundant Infiniband, I think you'd be looking at 100-130k if I recall correctly. Pricing may have changed, and that doesn't necessarily reflect what you'd get price-wise.

LeftHand and EqualLogic will do you well, too, but note, those are block-based iSCSI products, and Isilon is file-based NAS storage. Different applications.

I'm curious to hear other peoples feedback here...

I can't think of any reason to actually use partition tables on most of my disks. Multipath devices are one example, but really even if I just add a second vmdk to a VM... why bother with a partition table? Why mount /dev/sdb1 when you can just skip the whole fdisk step and mount /dev/sdb ?

Why create a partition table with one giant partition of type lvm, when you can just pvcreate the root block device and skip all that? What do the extra steps buy you besides extra steps and the potential to break a LUN up into parts (something I have no intention of ever doing).
Speaking as someone who has nuked 1TB of production porn (Playboy) because a drive without a partition table looked just like the new drive I was going to format for a quick BACKUP of said data, it can be helpful :)
