Our I/O Virtualization Technology Part 2: Taking Full Advantage of SSD Performance with Micron’s PCIe SSD Sharing Technology

By Justin Strong - 2012-10-03

In my previous post, I introduced our new I/O virtualization (IOV) technology, which can provide numerous benefits to data centers. Today, I’m talking about the benefits of PCIe sharing to SSDs.

Micron offers some of the highest-performing SSDs in the industry. Take our RealSSD™ P320h PCI Express (PCIe) drive, for example, with its sustained read speeds of over 3 GB/s and random read IOPS approaching 800,000. While these performance numbers are impressive, a fixed amount of SSD storage for each server is not always the best solution. Large datacenters with high-performance computing needs rarely have static environments. Applications, servers, users, and configurations are constantly changing. And the growing number of hypervisors utilizing virtual machines is adding complexity. Bottom line—predicting the amount of SSD storage required for caching, tiered storage, or even primary storage is nearly impossible. Enter our new PCIe Sharing, which is the perfect fit for this situation.

PCIe SSDs have high performance and low latency, and any sharing technology must have the same performance attributes in order for servers to take full advantage of the SSD’s capabilities. Ethernet and fibre channel, while providing performance sufficient for SANs, do not have these performance attributes. Our PCIe sharing technology does. It also reduces costs and configuration efforts.

Using PCIe sharing technology to share PCIe-connected SSD resources provides the flexibility of sharing SSDs across multiple servers with the performance and latency of a dedicated PCIe SSD. Data centers get the best of both worlds.
