Computerworld - GRAPEVINE, Texas -- When it came to managing most of AOL's 6 petabytes of data, a Fibre Channel SAN sufficed. But for its most critical relational database, AOL found that the SAN was too constrained and caused its IT shop to miss business unit service levels more than 50% of the time.

After investigating what may have been causing I/O bottlenecks, AOL found the problem was backend storage. To fix the problem, AOL decided to build a 50TB storage area network (SAN) from solid state technology.

The upgrade worked, increasing throughput to the SQL database by four times over the Fibre Channel SAN, while still providing storage admins the flexibility to migrate data between storage systems because the NAND flash memory sat behind an existing virtualization appliance, which aggregates all of the backend storage and serves it up as from a single pool.

Not news to us, but this will set an excellent precedent towards showing business's that SSD's are truely ready for enterprise work.

But love can be expensive. Without offering an exact price tag, Pollack said the solid state array cost AOL about $20 per gigabyte, which with 50TB of capacity, adds up to about $1 million.

Yep.

$50,000... $1,000,000... same thing really.

Wait.

WHAT...THE...

It'd probably be more cost-effective to develop a RAID controller that can pass on TRIM commands, then use consumer SSDs in RAID1

50k doesn't get you much in terms of enterprise hardware.

Companies like dell will charge you 10k just for a cheap smaller/midsize business 4 TB san w/ typical 7200 rpms sata drives and 4-6 nics.

Thats insane, how can they charge so much? The service that comes with it?

Damn, $20 per GB? I know it's enterprise level and all but that's some ridiculous markup.

Also who the hell still uses AOL for anything? What is that, 6 Petabytes of aim cybering?

Businesses have budgets.

They just spend the money to get the job done. Nearly everything offered to businesses and the government is ludicrously priced.

Pretty much service and their guarantee of compatibility. On items like that if something goes wrong you don't have to do much more than dial a number and tell them you have a problem and they'll have guys on site or new hardware shipping to you asap.

Wow that's awesome a enterprise 50 TBS array should be monstrously fast !


For sure the bottleneck has been eliminated!

Don't second guess enterprise storage unless you actually know what you're talking about. These guys know vastly more about their usage, system, and performance. They didn't just blindly invest $1M and risk disruption.

LOL.... $50K won't even buy 10TB of HDD enterprise storage.

1) There are no RAID controllers than can support TRIM to an array.
2) This is a SAN on fibre.
3) Also "Pollack also considered using solid state drives in servers, but didn't because he would not have been able to cluster them into his SAN, they don't offer the required capacity, such drives could not be non-disruptively swapped out and data couldn't be migrated between systems."

IBM changes $10-20K per year for 1TB of storage (high-performance HDD redundant SAN and backup site, 24-hr support, 24-hr replacement).

Liability. If the system goes down for a day, it will cost more than $1M losses. If the data is lost, it will cost hundred of millions in loss.

Not really. It actually is cheap considering redundancy and the hardware required to support it. A single NIC costs more than your entire system.

AOL has outlived AGP and will outlive cockroaches; it may even be around to witness the release of DNF.
