The all FLASH/SSD storage trend is unstoppable, as is the case with NAS services in the future, with a number of startups supporting all-SSD NAS storage services, including EMC Isilion, all-flash nodes.

High IOPS capability under flash scenarios, corresponding to NAS should be OPS operational capability. such as random small file reading and writing, analysis and hotspot acceleration. On the NAS support for the database. For example, GPFs NAS on Purescale, Oracle support. Assume that storage media uses SSDs. There will be significant improvements in database performance and processing power.

Today we look at Purestorage's flashblade SSD nas product, EMC Isilon all Flash. And the all Flash FAS A-series SSD NAS product based on the traditional data ontap.

First of all, recall the Flasharray product, Flasharray//m Hardware is an upgraded version of the previous generation FA. In contrast, there are improvements in both capacity and performance. Flasharray//M20 is an entry-level device. The 3u-5u box supports scaling from 5TB-40TB to 250TB of usable capacity. Performance up to 200,000 (32K block) iops,//m50 in 3u-5u box supports 20TB and 176TB bare capacity, supports scaling to 500TB usable capacity, 270,000 IOPS.

The MLC Flash chip is used in the flasharray//m new array. Purestorage feels that MLC will be the trend that he is able to achieve SLC the same durability level.

Flashblade is a rack-scale flash system for pure storage. Using multiple protocols to access unstructured data is also the first set of object-based, all-flash, non-structured data storage systems on the market. Only its rack size differs from EMC's DSSD rack-scale flash system. In addition, the latter is mainly oriented to delay-sensitive structured data.

Flassharray//m is primarily oriented towards structured data. As a matter of fact. Flashblade is a complement to the existing Flasharray//m programme.

Flashblade is intended for potential large-scale unstructured datasets in use case design. such as the Internet of Things, log data, and machine data.

It can be linked to large-scale simulation tasks, including traditional weather forecasts and airflow analysis, security threat analysis, and big data analysis, and more.

Flashblade can increase storage capacity, IO and metadata performance, transmission bandwidth, and client connectivity in non-destructive conditions by adding blade devices. The level of consistent low latency it provides should go far beyond disk-based object storage systems.

The Flashblade design uses 15 aligned blades in 4U space, and the device is capable of achieving petabytes of storage capacity by scaling out.

The blade is a complete storage node server.

The blade contains the elastic Fabric Connector for implementing an external 40GbitE network. Support NAND Raw storage capacity of 8 TB to flasharray//m TB (similar to the system, using Samsung's 3D V-nand TLC), built-in Nv-ram to provide powerful buffer storage capacity. In addition with ARM CPU core and a piece of FPGA. The inter-blade network is connected to the compute and memory card through a PCIe card-specific protocol.

The elasticity software is responsible for providing a common set of scale-out object storage systems that can be accessed via file NFS, CIFS, and object protocols. At the same time have the future of new protocol adaptability, that is, the forthcoming HDFs.

The features of the elasticity software stack include Elastic core mates for end-to-end garbage collection, LDPC error recovery, and snapshot functionality. Replication capabilities, data reduction and deduplication, encryption and other enterprise storage functions.

Elasticity has a set of namespaces and metadata addressing capabilities. Ability to create more than 100 million unique objects/files per second. It provides a set of Web GUI management interfaces and Rest API interfaces.

On Dell EMC World 2016, the Isilon all Flash product was unveiled with the new Onefs software, which enables integrated tiering and data acceleration with older storage nodes, so Dell EMC also defines Isilon all Flash is an accelerator for the data lake.

The new all-flash Isilon does not use NVRAM to save logs, but instead uses flash memory directly.

All-Flash Isilon actually has only one hardware form, placing 4 nodes in a 4U chassis. Each node supports a 15 SSD disk.

The capacity of the disk can be selected, there are three kinds of 1.6TB,3.2TB,15.4TB. The interconnect interface of the node must be IB or 400,000 trillion, capable of scaling up to 100 chassis, or 400 nodes, capable of supporting up to 100PB capacity.

NetApp released the All-Flash AFF 8000 series last year after a series of restructurings (EF series, Flashray) and acquisitions (SolidFire) in the flash market. This product improves performance and data management capabilities. Improve flash performance and efficiency with software innovations such as NetApp Data ONTAP flashessentials.

Recently, NetApp's AFF a700s series includes A200 entry-level systems, A300 mid-tier systems, and a700s high-end systems. A-series storage systems provide users with the highest scalability performance in the industry. Take advantage of the NVME network-ready cluster architecture, leading to support for the TBSSD, 32Gb fiber and 40Gb Ethernet connectivity capabilities.

The AFF a series fully supports complex public cloud environments. Enable users to connect to open solutions for public clouds including AWS, Azure, IBM Cloud, and more. Extended FAS scale out NAS capability. Very good support for different scenarios NAS file application load.
