Flash Arrays – Speeding up access to data
We supply all flash arrays to provide applications such as OLTP, Databases, Virtualisation for Server or Desktop, VOD, VDI, VR, 3D modelling, video editing, molecular modelling to deliver maximum IOPS and capacity based on the application requirement. In order to achieve the performance, enterprise flash arrays achieve, we also need to look at potential bottlenecks in the network to maximise the performance and alleviate any unforeseen issues. By deploying an enterprise flash storage array you will typically see a 10x or more performance increase in your system environment which in turn leads to increased productivity. Although the cost of flash storage is coming down the cost per Terabyte is still 2-3x that of a comparable disk storage solution.
Flash Array Storage vs Hard Disk
Enterprise flash storage capacities are slowly increasing and at present stand at 2TB for an SSD drive, although larger capacity drives have been announced by Seagate and Samsung they are not yet commercially available. With hard disk capacities of 14TB and rising and likely to reach 20TB by 2020. An SSD flash drive has many benefits over hard disks and these are:
- Increased Performance
- Far Lower Latency
- Higher IOP Rating
- Lower Energy Use
- Weigh Less
- Higher Shock Rating
- Run Silently
The differing types of flash storage
All of the systems below contain flash storage in one form or another.
- Hybrid Storage – Designed as an intermediary between spinning disks and flash. Introduced over 5 years ago, these were the first storage platforms to take advantage of flash, could provide significant performance improvements, albeit at far less cost than an All-Flash Array.
- SSD Storage – Based on 2.5″ SSD drives, these are primarily designed to replace 1 or 2 drives in an existing disk sub-system to enhance performance. The issue is that a normal RAID storage system cannot handle the massive performance SSD’s provide, basically they overwhelm the data bus. So there is little or no point in replacing 16x spinning disk with SSD as it probably won’t be able to handle it.
- PCIe Storage – Now flash operates at the speed of the bus rather than the SAS/SATA controller. The primary issue with PCIe is the number of controllers that can handle the extra bus speed and the lack of standard compatibility between storage vendors which could cause interoperability issues. Over time these issues will all be incorporated in future versions of PCIe, but for now, it’s a path that hasn’t been tried, tested or approved by standards committees.
- All Flash Storage – Designed to take full advantage of SSD drive technology, allied to high-speed controllers, advanced data analytics and a relatively future-proof upgrade path, these systems are designed to provide the simplest and easiest out of box uses with a number of host interfaces allowing you to connect and go.
Buying a flash array storage solutions is a high investment and an unknown risk for many companies as they have always bought disk-based systems. Flash storage today is as reliable as hard disk systems and can scale to provide PB’s of usable space. They can have multiple flash controllers, support the latest flash technology developments including NVMe, clustered and provide scalability for performance and capacity.
