EchoStreams FlacheSAN2 Review Discussion

12 posts in this topic

The EchoStreams FlacheSAN2 provides organizations with a customizable solution with its 48-bays for 7mm SSDs that fits into just 2U of rack space. EchoStreams is more than happy to build the system to an organizations' specs by installing a range of hardware to meet their exact needs. That makes the FlacheSAN2 ideal for organizations who already have an IT infrastructure plan in mind and don't need a pre-configured/turnkey solution. In our test system, we loaded up the FlacheSAN2 with four Adaptec 71605 RAID cards, four Mellanox ConnectX-3 56Gb/s dual-port InfiniBand adapters and 48 Toshiba HK3R2 SSDs for exceptional shared storage performance. The SSDs in particular give us one of the best performance/$ blends available with enterprise SSDs. Additionally, our FlacheSAN2 features a dual-processor Intel motherboard with twin Intel E5-2697 v2 CPUs to help drive plenty of I/O and bandwidth over the wire.

From a 2U platform, there aren't many competitors that can meet or exceed those numbers in this particular footprint.

Any chance of elaborating? Just curious...

Looking at the Violin WFA for example, the FS2 was able to push out much higher bandwidth and more IOPS. there were some latency differences though.

Hey Kevin.... so finally I see you managed to put together a RAID array with amazing 13 GB/s read and 6 GB/s write.... Was this basically just using storage spaces to create a RAID10 array? Have you seen anything else close to this is raw data transfer performance? Is this a single volume or multiple volumes?

I ask because It says "4 x 12 SSD Storage Spaces Mirror Pools (12 SSDs per HBA)" .... were the transfers happening on four volumes or one RAID 10 volume? As you may recall I'm looking to build a very high performance SMB file server and these numbers seem very interesting.

This was across multiple volumes. 4 Pools, each pool had 2 shares... so 8 total shares active.

Single volume will be tied to the performance level of the HBA... so multiple threads probably around the 5-6GB/s range peak read.

Its still built up, but any single volume spanning multiple HBAs will be limited to the performance of just one HBA. We built the environment up where each volume was contained to a single HBA... aka we didnt have a 48 SSD single volume.

Someone with a better understanding of drivers and interrupts would be able to explain it better... but that has been the limit we've seen across the board, even with a multi-thread workload. The hopes of getting a 5-6GB/s single file transfer might be a problem until we have something faster than storage connected to PCIe 3.0 8x lanes.

It could be multiple files to take advantage of threading better..... but yeah, single volume.

Does it have something to do with syncing the request stack?
