If it’s really going to be a revolution, Intel and Micron have got to start talking about it more seriously and enterprise vendors have to start delivering 3D XPoint-powered products.
Do you like IOPS? How about millions of IOPS? Ray Lucchesi gives a breakdown of NVDIMMs, including where they are at in terms of development and usability. What surprised me was how relatively robust the hardware is compared to the software. Right now there is no standard on how to address the disks on a file system level, which is needed to really leverage their faster performance. It’s an interesting introduction into the technology.
Adam Banks at Ars Technica has a great writeup on how cheap RAM changes storage, and in effect system architecture. Cheap RAM means the ratio of RAM to storage is changing in the database, allowing for more data to be loaded and reducing disk reads. The problem? Well volatile memory is… volatile, not necessarily something […]
EMC VFCache (nÃ©e Project Lightning) is a fairly simple offering: A server-based PCIe flash card that acts as a read cache with no integration with storage arrays or hypervisors. But EMC’s entrance into the host-based flash storage market is a powerful demonstration of the wave of disruption caused by flash-based storage and high-performance computing.
The new Nimbus Data E-Class comes just at the right moment, with 500 TB of capacity, a fully redundant â€œdual activeâ€ controller architecture, massive performance (even InfiniBand), and complete feature set (once VAAI is released).
PCIe SSDs like Micron’s new P320h offer mindbending performance and enterprise class reliability. Although expensive, these devices are in an entirely different league from any other storage option. Micron promises to bring the PCIe P320h to market at nearly $15 per gigabyte, a substantial discount over other PCIe SSD competitors.
