Review: Pure Storage FlashBlade Delivers for Higher Education Research Institutions

Dynamic, flexible storage supports data-intensive, high-performance computing.

Universities, particularly those with a research emphasis, can be similar to large enterprises in their use of high-performance clustered systems, data mining and real-time data processing. 

Such systems need the fastest possible storage — in throughput, low latency and maximum input/output operations per second — and constant data access.

The Pure Storage FlashBlade system delivers, with microsecond latency, up to 1.5 terabytes per second of throughput and 2.5 petabytes of capacity. 

The scale-out architecture yields maximum performance in four rack units, with Peripheral Component Interconnect Express (PCIe) access and Non-Volatile Memory Express (NVMe) flash storage. Plus, power-safe, battery-backed RAM ensures that transactions complete.

FlashBlade Makes It Easy to Expand Capacity and Performance

The Pure1 system allows for management of up to five chassis and 75 blades through one pane of glass. Automated clustering and N+2 redundancy with self-healing mean that little setup and maintenance are required, even with large systems

Smart endurance tunes the array for optimum allocation, wear leveling and garbage collection, while flash-level quality of service ensures that critical data gets the best performance. 

Installation is straightforward, and once the system is set up, users can easily install additional blades to increase capacity and performance.

Pure Storage FlashBlade

Pure Storage has included sophisticated features: Metadata, files and objects are distributed across multiple blades, ensuring redundancy, fault tolerance and improved I/O, since responses stream from multiple blades simultaneously. The system supports standard storage protocols, including Amazon S3 objects, NFS, SMB and HTTP, as well as block-level devices, with built-in thin provisioning, compression, encryption and data locking, and snapshots

It’s also fast enough (about 1 gigabyte per second, per blade) to support thousands of systems for virtual desktops as well as data lakes, Big Data and HPC systems with one set of five chassis. 

With speed, power and an extensive feature set, the FlashBlade system is a versatile solution for any institution

Features Support Redundancy and Rapid Reconstruction

Pure Storage engineered the FlashBlade system for flash and NVMe flash. Many older systems have a long history of data center use, but this is a mixed blessing. 

Those systems also have a long legacy of old protocols that are based on hard disk standards, which means that old commands and methods of accessing data (dating back to the 1960s) are included in many modern standards for addressing storage.

This adds overhead to modern devices that are more like RAM than traditional rotating storage in the way that they’re accessed. Pure Storage bypasses those old protocols and standards with an all-flash system

To ensure redundancy and fault tolerance, the FlashBlade system uses erasure coding as well as variable block sizes, distributing files across multiple blades in multiple chassis with sufficient error correction so that even if any of the pieces are lost, the whole file can be quickly reconstructed. 

In addition, pulling files from multiple locations on multiple blades increases throughput. Here, that happens automatically, with no need for planning on the part of the administrator

The system is elastic and dynamic, self-optimizing for maximum throughput on files that see the most use, without sacrificing performance on other files.
