Startup Pure Storage Inc. and solid-state storage maestro Texas Memory Systems (TMS) Inc. today
launched an all-flash storage array lineup regulating multi-level dungeon (MLC) peep to move down prices.
Pure Storage came out of secrecy with a Pure Storage FlashArray FA-300, that a startup’s
executives wish will move “flash to a masses” with a cost indicate of $5 per gigabyte of usable
storage.

Pure Storage’s FA-310 and FA-320 enclose 2.5 in. SATA-based MLC drives. The FA-310 is a single
controller complement that supports 5.5 TB or 11 TB of tender capacity, while a FA-320 has two
controllers and from 11 TB to 22 TB of tender capacity. Assuming a 10-to-1 deduplication ratio brings
the limit tender capacities to 110 TB for a FA-310 and 220 TB for a FA-320.
Texas Memory Systems combined an craving MLC (eMLC) complement to a lineup of
all-flash
storage devices. The TMS RamSan-810 comes in during approximately $13 per GB, roughly half the
street cost of a single-level dungeon (SLC) RamSan-710. The 10 TB RamSan-810 can scale to 400 TB
with a opening of 160 GBps and 12.8 million IOPS in a 40U rack, according to TMS.
A new face in peep storage
Newcomer Pure Storage joins a tiny organisation of vendors offered all-SSD arrays, including TMS, Nimbus Data Systems Inc. and SolidFire. Pure Storage uses SSD drives from Samsung, a vital financier that
has helped a startup assemble $55 million in funding.
The FA-300 inclination have active/active clustered controllers for high availability, with two
six-core Intel Westmere CPUs (12 cores) per controller or 4 CPUs (24 cores) per array. Each array
has 48 GB of DRAM per controller, and additional non-volatile RAM (NVRAM) to insist information in the
event of a energy loss.
“The fun around here is that CPUs are cheaper than flash,” pronounced Matt Kixmoeller, Pure Storage’s
vice boss of product marketing/management, referring to how a FlashArray uses CPU-heavy
deduplication program to revoke a cost of flash. “Our concentration is all-flash and we trust we can
deliver peep during underneath a cost of a hybrid [flash and tough drive] solution.”
The FA-300 array is in a fourth beta contrast release, and will be generally accessible by the
end of a year. Final pricing will be set closer to release, Kixmoeller said, nonetheless Pure
Storage has sloping a palm with a $5 per gigabyte claim.
The $5 per gigabyte cost (which includes high availability) takes into comment hardware,
software and assumes a 5-to-1 information reduction, pronounced Michael Cornwell, Pure Storage’s executive of
technology and strategy. The association skeleton to come to marketplace with a most cheaper cost indicate than
other all-flash array companies. Nimbus Data has a cost per gigabyte during usually over $12.
Unlike Nimbus Data, that keeps costs down partially by production a possess SSDs, Pure Storage
gets SSDs from Samsung for a arrays. However, Cornwell pronounced Pure Storage will keep a cost low
because of how it manages information on a peep drives with a Purity handling system. The Purity
software handles inline data reduction by tellurian deduplication, application and skinny provisioning.
Also, a program sends I/Os in together to a SSDs to urge opening and refreshes a data
on a cells to keep a electrons quick so that information doesn’t fade.
“We’re means to use MLC in an craving sourroundings since of how we conduct a flash,”
Cornwell said. “Our program is always lovely a information so we never knowledge that event.
We’re in a credentials relocating information to opposite cells to safeguard a information doesn’t blur away.”
Pure Storage also offers information insurance by a exclusive RAID-3D. “We optimize RAID for
flash,” Cornwell said. “Flash doesn’t have a emanate of locality of information that hoop has. We’re able
to lay out information in a hierarchical manner, that enables improved opening of a information store. The
way we lay out a information allows for quick reconstruct times.
Nimbus Data and TMS call their peep eMLC, while Pure Storage and Samsung tag theirs MLC. Until recently, MLC was
considered good usually for consumer inclination while SLC was a choice for a enterprise. The high
price of SLC has singular a adoption, though, call peep vendors to tweak MLC to urge its
reliability and performance.
Mark Peters, a comparison researcher during Enterprise Strategy Group, pronounced there’s not indispensably a
difference between eMLC and MLC. “The ‘e’ of eMLC is to communicate that we have a program in the
system to overcome some of a fundamental hurdles with MLC,” he said. “Pure Storage has management
software on tip of a MLC. They’re usually not job it eMLC.”
