Flash, Flash, Flash, Flash…Oh, and Did We Mention Flash?

Summary Bullets:

  • Flash technology has proven itself in the role of the high-performance pinnacle of the storage stack, but a few companies are looking to redefine it to accommodate the growing number of large, in-memory applications.
  • Upcoming offerings from several vendors are looking to move flash even closer to the compute layer, and this has the potential to remap the traditional CPU/memory architecture in a server near you.

I’ve had the pleasure of attending a number of technology conferences recently, and aside from “hybrid cloud” the one message that crosses over all of them is the overwhelming interest in flash memory technology and how it can improve the performance and flexibility of your data center. We all know that flash isn’t really all that new, flash-based SSDs and memory cards have becoming the de facto storage platform for almost every portable device, but adopting flash for enterprise-level applications has taken a little longer as vendors scrambled to insure that it truly meets the reliability, performance, and cost structure expected for high performance, high duty cycle applications. The obvious first-case applications focused on storage vendors who found that the SSD technology and form-factor was a perfect match for use as a caching layer at the very top of the storage stack in the conventional NAS/SAN model. There were also a few forward-looking vendors like Fusion-IO and OCZ Technologies that chose to decouple flash from the storage bus and upgrade it directly to the PCIe bus.

Diameter Signaling Over IP Exchange Promises Bright New Horizon for 4G LTE Roaming

Summary Bullets:

  • Diameter signaling is very complex and can be costly for mobile network operators (MNOs) to deliver
  • Wholesale carriers are moving in to help solve these complexity issues on behalf of MNO clients, and in the near future more widely available 4G roaming will help business users be more productive while on the road

Whilst Diameter signaling and IPX seem purely technical terms that have little to do with enterprise IT and communications, the fact is, the implications of these technologies on the way we can be productive while on the move are considerable. Imagine leaving your home 4G network, getting on a plane to travel to another country, and within minutes of landing, zap! you are once again able to enjoy high-speed mobile access and enterprise-quality video and voice. However, users are going to have to be aware of how their cross-border ubiquitous 4G LTE mobile experience is going to cause a huge spike in the monthly bill. We are all familiar with the high data roaming costs that can come with mobile broadband roaming, and therefore the enterprise customer needs to be continually pushing mobile vendors for fairer terms and prices, and already begin conversations on cost effective widespread 4G LTE roaming. Vodafone, for example, has recently suggested that 4G doubles data usage and that it expects 4G to increase mobile data revenues, including roaming, even in the light of incoming EU roaming legislation.
