Comparing SAN and NAS
Both SANs and NAS are based on open industry-standard network protocols—Fibre Channel for SANs and networking protocols such as TCP/IP for NAS. While SANs support a broad range of applications—including providing storage for NAS appliances—NAS storage is typically limited to applications that access data at the file level. Regardless of their differences, both SANs and NAS play vital roles in today’s enterprises and provide many advantages over traditional server-attached storage implementations.


NFC forecast dims at Gartner
For 2013, NFC-related transactions will make up only 2% of total mobile payment transactions, growing to 5% in 2017, Gartner said. Those percentages translate into about $4.7 billion for NFC-related payments globally in 2013, increasing to about $36 billion in 2017. In the previous Gartner forecast, the 2017 value of NFC payments was expected to reach an estimated $60 billion.


Tiering storage: Best practices to promote efficiency
Tape has always played the role of tier-three storage because of its extraordinarily high capacity and low per-gigabyte cost, while we've recently seen flash SSD suggested as a tier-zero layer because of its super-fast performance, very high cost and comparatively low capacity. In between these layers, we see tier-one storage comprising 15,000 rpm Fibre Channel (FC) or SAS drives and tier two representing lumbering, high-capacity, low-cost SATA arrays.


The Benefits of a Reverse Proxy
A reverse proxy is server component that sits between the internet and your web servers. It accepts HTTP requests, provides various services, and forwards the requests to one or many servers. Having a point at which you can inspect, transform and route HTTP requests before they reach your web servers provides a whole host of benefits. Here are some:


HTTPS is confusing one of the core metadata tools of the Internet: HTTP Referrers. HTTP Referrers disappear when going from HTTPS to HTTP, but, more worryingly, sensitive HTTPS Referrers still get carried when going from HTTPS to HTTPS. Most secure applications aren't aware of where their HTTP Referrers do or don't go. Don't worry though: there's hope. Or at least meta hope.


But despite all the virtual machine (VM) hoopla, not all SQL Server environments should be virtualized. Issues around licensing, performance, availability and support must be considered before SQL Server can be committed to a virtual environment. Failure to do so could result in a substandard production environment that wears the VM label proudly but fails to deliver on the VM promise.


Windows Phone to overtake the iPhone? It will happen.
A new Canalys report says that by 2017, the iPhone will have a 14.1 percent market share, with Windows Phone nipping at its heels, with a 12.7% share. In 2012, the report says, the iPhone had a 19.5% market share, and Windows Phone a 2.4 percent market share. Android dominates now and will dominate in the future, with a 67.7 percent market share in 2012, and a 67.1 percent market share in 2017.


Dell Challenges Cisco, HP With Converged Infrastructure Lineup
Dell on Tuesday unveiled an expanded range of converged infrastructure products, opening the technology, which Dell had previously pitched to large enterprises, to new classes of customers. Designed to simplify daily IT tasks and enable companies to more rapidly provision and deploy virtual machines, the offerings not only combine storage, networking, and computing into a single chassis but also bring all components under the control of a single management console.


Mobile and cloud to reduce enterprise costs by $28tn by 2015
The data also reflect a growing trend towards bring-your-own-application (BYOA), which is a huge challenge for IT. According to Ovum’s survey, roughly 50 per cent of those bringing their own tablets or smartphones to work are doing so without the knowledge of their IT departments. “IT needs to get on board or risk losing out,” said Adrian Drury, practice leader of consumer impact IT at Ovum.


Five web-based network troubleshooting tools
Network troubleshooting can run the gamut of possibilities. From hardware to software to external, uncontrollable forces, to powerful Jedi mind tricks. When you’re troubleshooting networking issues, the problem can often point toward many and varied issues. When that happens, you’ll want to have access to tools to help you diagnose the issue. One place to turn for such a tool set is the good old Internet.
