SR-71mach5 SpeedServer

Posted on by — 1 Comment ↓

ION recently launched it’s flagship SR-71mach5 SpeedServer™ which continues to deliver on the SR-71 legacy of all-SSD storage for “disk-impossible performance”.  This new server incorporates new technology throughout yielding more processor cores, more and faster memory and much more random I/O performance. Standard processors in the “mach5” are two 12-core 2.6GHz Intel® Xeon® E5-2690 V3, but the full Xeon E5-2600V3 processor lineup is available.  Continue reading SR-71mach5 SpeedServer→

There are many opinions on the benefits and liabilities of SSD RAID floating around the Internet; ION’s experience with SSD RAID differs dramatically from some of it.  ION’s SR-71mach4 SpeedServer™ is a server and storage platform optimized for and with SSD RAID.  This article shares some observations on the performance and endurance of SSDs in RAID usage, and examines and compares performance in different Continue reading SSD RAID→

Spinning Rust is (almost) Dead, Part 3, SSD Price vs. Performance

Finally, we get to the question, “What replaces hard disk drives?” As many people already know, the answer is solid state disks or SSDs. SSDs are made today to fit the shape, size and interfaces used by hard disk drives (HDDs), but they consist mostly of Flash memory instead of spinning rust, plus a controller and some RAM for buffering, just like a rotating Continue reading Spinning Rust is (almost) Dead, Part 3, SSD Price vs. Performance→

Spinning Rust is (almost) Dead, Part 2, Disk Drive Physics

That brings us back to spinning rust. To understand the limitations of rotating hard disk drives, it is important to understand the technology.  With a basic grasp of how a disk drive works, the mechanical limitations  quickly become obvious. If you are accessing data sequentially in big long chunks, where the disk can read an entire track, move over just one track and read Continue reading Spinning Rust is (almost) Dead, Part 2, Disk Drive Physics→

Spinning Rust is (Almost) Dead, Part 1, The Pace of Technology

“Spinning rust?” you may say? Yes, rust, or another iron oxide, is the ferromagnetic coating on the platters spinning inside every hard disk drive.  To read and write your data an actuator arm, driven by a separate motor moves a tiny recording head over each platter surface, flying on a microscopic layer of air to change the magnetic polarization one bit at a time.  Continue reading Spinning Rust is (Almost) Dead, Part 1, The Pace of Technology→
