In recent years there has been a significant increase in the number of organizations considering flash-based solid-state drive (SSD) solutions for data center storage. While solid state drives have been used in consumer products such as MP3 players for a decade or more, data center deployments are new in the last couple of years. SSD implementations have provided organizations with orders of magnitude improvements in IO performance compared to traditional hard disk drives (HDD).
A single SSD can deliver performance that might take hundreds of HDDs as it eliminates storage bottlenecks for applications that require fast performance and low latency. Today’s SSDs are also highly reliable with a life expectancy around ten years, and are much more power efficient than mechanical, spinning HDDs. These features make SSD attractive from an operational perspective, but the high cost of most SSD solutions compared to traditional disk arrays is making the investment hard to justify for most organizations.
The WhipTail XLR8r is an SSD appliance that supports up to 12 TB of MLC flash in an industry standard rack-mounted 2U form factor. The WhipTail Racerunner OS (RROS) is designed to overcome the write performance and longevity challenges associated with cost effective MLC flash technology. It performs random writes faster than random reads, a capability that is ideally suited for a virtual desktop infrastructure as multiple users sharing a common desktop image flips IO from mostly random reads for a single user to mostly random writes for a mix of users.
This ESG Lab Validation report documents the results of hands-on testing of a solid state drive (SSD) solution from WhipTail Tech with a focus on cost effectively solving storage performance challenges in a consolidated virtual desktop infrastructure (VDI).
