We know that SSD's help any system perform better by reducing the storage bottlenecks we all experienced from hard disk drives. But how far can flash storage go in increasing performance if money is no object?? Enter the multi-million dollar world of supercomputers. Historically supercomputers have relied on the addition of more CPU cores to increase performance, but two new system projects funded by the National Science Foundation (NSF) will try a different approach: obscene amounts of high-speed flash storage!
The news comes as the NSF is requesting a cool $7 billion in research money for 2015, and construction has apparently already begun on two new storage-centered supercomputers. Memory and high-speed flash storage arrays will be loaded on the Wrangler supercomputer at Texas Advanced Computing Center (TACC), and the Comet supercomputer at the San Diego Supercomputer Center (SDSC).
Check out the crazy numbers from the TACC's Wrangler: a combination of 120 servers, each with Haswell-based Xeon CPU's, and a total of 10 petabytes (10,000TB!) of high performance flash data storage. The NSF says the supercomputer will have 3,000 processing cores dedicated to data analysis, with flash storage layers for analytics. The Wrangler supercomputer's bandwidth is said to be 1TB/s, with 275 million IOPS! By comparison, the Comet supercomputer will have “only” 1,024 Xeon CPU cores, with a 7 petabyte high-speed flash storage array. (Come on, guys... That’s like, wayyy less bytes.)

The supercomputers are part of the NSF's “Extreme Digital” (XD) research program, and their current priorities are "relevant to the problems faced in computing today”. Hmm, kind of makes you want to run a big muilti-SSD deathwish RAID, huh?

Ottawa-based Diablo Technologies unveiled a new flash storage technology yesterday that it calls Memory Channel Storage. As the name suggest, the storage technology puts NAND flash into a DIMM form factor and interfaces the persistent storage directly with the processor via the integrated memory controller.
The Memory Channel Storage (MCS) is a drop-in replacement for DDR3 RDIMMs (Registered DIMMs) in servers and storage arrays. Unlike DRAM, MCS is persistent storage backed by NAND flash and it can allow servers to have Terabytes of storage connected to the CPU via the memory interface instead of mere Gigabytes of DRAM acting as either system memory or block storage. The photo provided in the technology report (PDF) shows a 400GB MCS module that can slot into a standard DIMM slot, for example.
Diablo Technologies claims that MCS exhibits lower latencies and higher bandwidth than PCI-E and SATA SSDs. More importantly, the storage latency is predictable and consistent, making it useful for applications such as high frequency stock trading where speed and deterministic latency are paramount. Further, users can get linear increases in throughput with each additional Memory Channel Storage module added to the system. Latencies with MCS are as much as 85% lower with PCI-E SSDs and 96% lower than SAS/SATA SSDs according to Diablo Technologies. NAND flash maintenance such as wear leveling is handled via an on-board logic chip.
Diablo Technologies is also aiming the MCS technology at servers running big data analytics, massive cloud databases, financial applications, server virtualization, and Virtual Desktop Infrastructure (VDI). MCS can act as super fast local storage or as a local cache for external (such as networked) storage in the form of mechanical hard drives or SSDs.
Some details about Memory Channel Storage are still unclear, but it looks promising. It will not be quite as fast in random access as DRAM but it will be better (more bandwidth, lower latency) than both PCI-E and SATA-connected NAND flash-based SSDs. It would be awesome to see this kind of tech make its way to consumer systems so that I can have a physical RAMDisk with fast persistent storage (at least as far as form factor, MCS uses NAND not DRAM chips).
The full press release can be found here.

A process shrink to 10nm wasn't enough for Samsung, they also doubled the density of their MLC flash storage to 128Gbits at a physical size of 170.6mm2. They claim write speeds of up to 18MB/sec and 400Mbit/s bandwidth through their toggle interface. Even better news for consumers is that this should be even cheaper than current MLC flash which will help continue to drive the price of SSDs down. Samsung didn't tell The Inquirer when we can expect to see these in devices but it should not be too long from now that we are doing longevity testing on this new Flash.
"MEMORY MAKER Samsung has announced that it is producing 128Gbit 3-bit multi-level cell (MLC) NAND flash chips for solid-state disk (SSD) drives"

Plextor, a company known best for its line of optical drives has announced a new SSD that offers up some impressive performance numbers. The M5 Pro is powered by a Marvell 88SS9187 Monet controller and claims to offer improved data protection and throughput even when the drive is near-full.
Plextor uses 128-bit error correction built into the Marvell controller in addition to a data hold-out algorithm in Plextor’s firmware to ensure that data reads from the flash memory as accurate as possible. Further, the drive offers up AES 256-bit full drive encryption to protect your data from prying eyes. The company further stated that the drives have undergone “rigorous high-temperature burn-in tests” to ensure reliability. The reliability aspects are the features that the company is touting the most in its press release, but the other half of the coin is performance.
Fortunately, if its numbers turn out to be true, users will not be disappointed. The Marvell controller is putting out some decent performance numbers. The M5 Pro SSD is capable of read and write IOPS of 94,000 and 86,000 respectively. Further, it can deliver a claimed 540 MB/s sequential read and 450 MB/s write operations. Not bad for Marvell at all!
According to Kathy Huynh, Product Marketing Manager for Plextor:
““In recent years, Plextor has been able to develop SSDs that deliver high real-world performance and sustained speed over the long-term. Our SSDs have one of the lowest annual failure rate in the consumer SSD industry. Now with the M5 Pro, we aim to use Plextor’s abilities to offer extreme data protection and give users total confidence in every single aspect of their drive.”
The new M5 Pro solid state drives will come with a five year warranty and will be available later this month. You will be able to pick up an M5 Pro in 128GB, 256GB, or 512GB capacities, though there is no word yet on how much they will cost. You can find more information in the company’s press release.
