While the speed of a VDI array has increased greatly due to improved CPU, RAM, network speed, and other advances, a common bottleneck for all of this speed relies in data storage arrays. Traditional hard disk drive (HDD) arrays are limited in the amount of data they can process and how much data can be accessed simultaneously.
New solid state drive (SSD) and flash storage solutions offer significantly improved speed and scalability for virtual client environments. A drawback of an all-flash storage array is the high cost of deployment & upkeep.
However, a new hybrid cloud model delivers many of the benefits of flash storage arrays with significant cost savings. By implementing hybrid storage arrays, organizations can deliver faster, better computing to its users in a surprisingly affordable way.
Hybrid Storage Solutions are More Affordable
New flash-based storage resolves many problems associated with virtualization (like bandwidth issues) but this comes at a cost that many organizations simply can’t afford.
Hybrid storage is affordable and while still giving enterprise-level organizations the the storage capacity they require.
Though hybrid solutions cost a little more than HDD-only storage arrays, the benefits mean they are a smart investment for organizations large and small who rely on VDI for daily computing.
Implementing Hybrid Storage Arrays
Here are three common ways hybrid storage arrays are implemented.
- Installing Flash Storage Alongside HDD Storage: This makes HDDs and SSDs interchangeable and is probably the simplest and easiest method to implement hybrid solutions.
- Shared Flash Appliance: With a shared flash appliance SSDs act as a persistent cache – similar to computers’ RAM – to improve how fast read and write applications are served to the end user. This means the flash storage can be used by multiple systems simultaneously. This also allows users the ability to experience high read/write speeds for applications while the disk storage system transfers data to and from HDD storage arrays. Through this method, flash storage can be installed on a PCI Express (PCIe) bus rather than a normal hard disk enclosure, delivering even faster speeds.
- Installing PCIe Flash Devices (SSDs) Directly on Servers: This dramatically increases the speed of desktop virtualization, effectively eliminating network latency between a CPU and persistent storage. Thus, VDI users experience performance similar to what they would have on a desktop, assuming memory and CPU number/speed is adequate.
Using Hybrid Cloud Storage in a Virtual Client Environment
Each of these hybrid storage solutions deliver better speed and performance for VDI users compared to what HDD-only solutions can deliver.
