This week, IBM announced its new line of x86 servers, and included among the usual incremental product improvements is a performance game-changer called eXFlash. eXFlash is the first commercially available implantation of the MCS architecture announced last year by Diablo Technologies. The MCS architecture, and IBM’s eXFlash offering in particular, allows flash memory to be embedded on the system as close to the CPU as main memory, with latencies substantially lower than any other available flash options, offering better performance at a lower solution cost than other embedded flash solutions. Key aspects of the announcement include:
■ Flash DIMMs offer scalable high performance. Write latency (a critical metric) for IBM eXFlash will be in the 5 to 10 microsecond range, whereas best-of-breed competing mezzanine card and PCIe flash can only offer 15 to 20 microseconds (and external flash storage is slower still). Additionally, since the DIMMs are directly attached to the memory controller, flash I/O does not compete with other I/O on the system I/O hub and PCIe subsystem, improving overall system performance for heavily-loaded systems. Additional benefits include linear performance scalability as the number of DIMMs increase and optional built-in hardware mirroring of DIMM pairs.
■ eXFlash DIMMs are compatible with current software. Part of the magic of MCS flash is that it appears to the OS as a standard block-mode device, so all existing block-mode software will work, including applications, caching and tiering or general storage management software. For IBM users, compatibility with IBM’s storage management and FlashCache Storage Accelerator solutions is guaranteed. Other vendors will face zero to low effort in qualifying their solutions.
During 2014, we’ll pass a key milestone: an installed base of 2 billion smartphones globally. Mobile is becoming not only the new digital hub but also the bridge to the physical world. That’s why mobile will affect more than just your digital operations — it will transform your entire business. 2014 will be the year that companies increase investments to transform their businesses, with mobile as a focal point.
Let’s highlight a few of the mobile trends that we predict for 2014:
Competitive advantage in mobile will shift from experience design to big data and analytics. Mobile is transformative but only if you can engage your consumers in their exact moment of need with the right services, content, or information. Not only do you need to understand their context in that moment but you also need insights gleaned from data over time to know how to best serve them in that moment.
Mobile contextual data will offer deep customer insights — beyond mobile. Mobile is a key driver of big data. Most advanced marketers will get that mobile’s value as a marketing tool will be measured by more than just the effectiveness of marketing to people on mobile websites or apps. They will start evaluating mobile’s impact on other channels.
