Pure Storage Releases All-Flash RAID Array Priced More Like Disk Array
, the all-flash enterprise storage company, last week announced that its next generation
FlashArray 300 Series
with the 2.0 release of the Purity Operating Environment is generally available. The FlashArray delivers higher resiliency via active/active high availability, FlashCare™ Technology and an enhanced Data Integrity Fabric. Additional advances include always-on encryption with zero key management, a new web user interface, command line interface, and VMware vStorage API for Array Integration (VAAI) support. Pure Storage makes it affordable for enterprises and cloud providers to broadly deploy
for their performance workloads, including virtual servers, virtual desktops, and databases and analytics workloads. With over 100 units shipped and production deployments for over a year, the FlashArray's performance, reliability, deduplication and compression are enterprise proven.
New Features in Next Generation Pure Storage FlashArray:
Active/active high availability (HA) - Within the FlashArray, multiple storage controllers are clustered via InfiniBand for high availability which allows for active/active IO handling on all ports of all controllers. The FlashArray provides
non-disruptive operations by healing around any hardware component failure, including a complete
failure of a FlashArray controller. Additionally, all storage components are hot-swappable (controllers, flash drives, NV-RAM modules), allowing for replacement of failed components without downtime.
FlashCare™ Technology - While competing arrays must rely on SLC or enterprise MLC flash (eMLC) to meet the endurance needs of enterprises, Pure Storage leverages standard
MLC flash to drive down cost. Pure Storage's FlashCare Technology delivers flash-cell longevity, and reliability that is comparable to SLC at a substantially lower cost, while simultaneously ensuring consistent latency. FlashCare employs unique IO management techniques, including an SSD-optimized data layout, wear leveling, geometry-aligned writes, IO micro-scheduling with QoS monitoring and non-blocking reads & writes. FlashCare enables the FlashArray to sustain years of multi-100,000-write IOPS workloads while maintaining consistent sub-millisecond latency without compromising the flash media or the data it stores.
Enhanced Data Integrity Fabric - One of flash's challenges is a higher bit error rate than rotational disk. The FlashArray implements a multi-layer Data Integrity Fabric, which combines overlapping user block-level and array page-level checksums with continuous background analysis to detect and heal data integrity issues automatically. This Data Integrity Fabric extends data protection beyond the already robust ECC (error correction code) that runs within each SSD.
Always-on full array encryption with zero key management - The FlashArray encrypts 100% of the data that is stored within the array. This protects user data from the theft or
loss of SSDs, whether that happens in the data center, in transit, while an array is being serviced, or as SSDs are being disposed during technology refreshes. Encryption has zero performance impact, and leverages a built-in key generation and management scheme that requires no end-user key management.
VMware vStorage API for Array Integration (VAAI) support - The FlashArray now supports the VMware VAAI APIs with vSphere 5.0, supporting write-same/block zeroing, ATS, UNMAP and thin provisioning.
New full-functionality web GUI and CLI - Designed with extreme simplicity in mind, the FlashArray now features an enhanced web management GUI and CLI. The FlashArray eliminates whole disciplines of storage management, including:
RAID configuration, space reclamation, setting tiering policies, carving LUNs, performance troubleshooting for spindle contention, and so on. The new FlashArray GUI enables the provisioning of storage with a single click, and provides in-depth historical performance analytics for no additional fee. Finally, the FlashArray is DevOps ready with a CLI designed for scripting and automation, offering complete programmatic management of the FlashArray.
"The industry is acknowledging solid state drives for enterprise applications as a highly attractive IT solution for next-generation server systems that offer outstanding energy efficiency," said Byungse So, Senior Vice President, Memory Product Planning and Application Engineering, Device Solutions, Samsung Electronics. "Samsung will continue to work closely with Pure Storage to develop advanced high-performance technologies to expand the green memory market."
"Storage has been constrained by mechanical disk and has thus been untouched by Moore's Law," said Scott Dietzen, CEO of Pure Storage. "Storage accounts for far too much latency, power, floor space and capital expenditure in the data center. We set out to push mechanical disk out of the performance path, and to do so by making all-flash storage less expensive than arrays of 15K rpm disk drives that do the performance heavy lifting today. With all-flash storage radically faster, more space and power efficient, simpler and more reliable than disk arrays and hybrids."
The FlashArray 300 Series is available in dual controller or single controller versions
with up to 12 host I/O ports, with either 8Gbit/s Fibre Channel or 10Gbit/s Ethernet supported. The arrays offer a raw data capacity of 5.5TB up to 22TB.
One of the features of the Purity Operating Environment is always-on de-duplication
, which enables the firm to claim an effective capacity of up to 100TB as well as delivering a high performance of up to 200,000 input/output operations per second (IOPS).
