Boost desktop performance

As an IT organization delivering a desktop service to users, key performance metrics such as boot/logon time, application launch time and overall desktop response time are critical to users accepting VDI and the success of a VDI project. Unfortunately, the performance of virtual desktops are often degraded by the amount of disk throughput available to each desktop (measured in IOPS) during peak usage periods. With Atlantis ILIO, IT organizations can deliver a virtual desktop that outperforms physical PCs and eliminates desktop performance degradation during period of IO storms such as boot storms, logon storms, patching and anti-virus scans.

Microsoft Windows 7 was designed with the assumption that it would run on a PC with its own processor, memory and exclusive access to a high throughput, low latency hard drive. In a conventional shared storage environment providing the data throughput required to support many hundreds or thousands of desktops all starting and launching applications at the same time, is a formidable and expensive challenge.

Increase IOPS per Desktop—Fast Virtual Desktop Hard Drives

Atlantis ILIO processes all common disk read/write activity locally at the Windows NTFS protocol layer on the same rack (Top-Of-Rack deployment) or in the same hypervisor (On Each Server Deployment), giving each virtual desktop a faster hard drive than a physical PC.  The impact of Atlantis ILIO on Initial system startup, logon performance and application usage is similar to that of replacing a physical PC’s standard hard disk with a Solid State Drive (SSD), making the virtual desktop, not only faster than a conventional desktop PC, but also significantly cheaper than upgrading every physical desktop to deliver equivalent performance.

Optimizing IO Traffic—From Random to Sequential

Microsoft Windows 7 is designed to optimize Disk IO activity. However, with VDI, the direct connection to a local hard disk is lost, and with it the benefits of the operating system’s IO optimization. Atlantis ILIO restores this optimization by intercepting all incoming disk IO and converting this random activity into deduplicated sequential IO that the storage infrastructure can process with maximum efficiency, further reducing the loading on the storage system’s disk controllers. This optimizes virtual desktop performance with minimal data center storage expense.
