ESXi 6.7 & IO Filters
Today VMware announced the general availability of ESXi 6.7, with a huge number of enhancements that VMware administrators will undoubtedly find exciting. Here at JetStream software, we’ve been eagerly awaiting the announcement as well.
Several months ago, we began the process of validating JetStream Accelerate with the VMware vSphere APIs for IO Filtering (VAIO) on ESXi 6.7. Today, as ESXi 6.7 is announced, we are pleased to be the first (and so far, only) vendor listed on the VMware Compatibility Guide with support for VAIO on ESXi 6.7.
Continuing What We Started
While JetStream Accelerate is a “new” product, it has deep roots. Our team originally collaborated with VMware in the development of the IO Filters APIs during the development of ESXi 6.0. At the time, we were still working at SanDisk, and our software for storage IO acceleration was called FlashSoft. (You can check out Cormac Hogan’s blog post about the software here.)
Like FlashSoft before it, JetStream Accelerate is integrated with the VMware vSphere hypervisor as an IO Filter and is managed through vCenter. It’s installed as a VIB and deployed across the cluster automatically. The software is managed through Storage Policy Based Management (SPBM) and is certified VMware Ready.
Since the first FlashSoft release based on VAIO, a lot has changed. We founded JetStream Software to address the need for better data management capabilities in cross-cloud environments, and we continue to apply our experience with public APIs including VAIO, vVOL and VASA for integration with VMware environments, both in on-premises data centers and in the cloud.
What hasn’t changed is our commitment to enabling IO acceleration with host-based non-volatile memory. The software is still installed as an IO Filter, because that gives the greatest assurance of compatibility and supportability to the VMware customer. That’s why, from Day One of general availability for ESXi 6.7, JetStream Accelerate is available as a validated VMware Ready solution.
Efficiency, Economy & Performance
JetStream Accelerate delivers greater efficiency to the data center, by reducing storage IO constraints on application performance and VM density. Testing has shown that application performance typically improves by 3x to 5x, although we occasionally see significantly greater improvements. Provided sufficient system memory and CPU, reducing IO bottlenecks has also been shown to enable increased VM density – allowing the number of VMs per physical host to increase by 2x to 3x in most cases.
One of the most overlooked benefits of host-based IO optimization is the improved efficiency of existing storage systems. Many customers have reported that by addressing storage IO performance in the host, they’ve realized greater value and a longer useful life from their storage systems. All in all, the solution brings greater efficiency, economy and performance to the VMware data center.
