August 09, 2012 10:14 AMThe best predictors of storage-related application performance have always been latency and IOPS. Hybrid SSD and HD systems are changing how those numbers should be viewed.
August 03, 2012 12:14 PMIn the first of a three-part series, Howard Marks describes how storage system throughput is a bad indicator of performance and how SSDs can vastly improve performance, even for entry-level storage systems.
May 29, 2012 09:21 AMImprovements in Silver Peak VXOA 5.2 WAN optimization include support for 512,000 flows and Xen and KVM hypervisors, as well as automated optimization for LAN tunneling protocols.
May 23, 2012 11:37 AMCiena demonstrates a virtual WAN that it says will improve low latency and bursty bandwidth applications. Learn more about the company's Data Center Without Walls concept.
March 27, 2012 09:00 AMApplications and initiatives like private cloud computing, virtualization and mobility are placing increasing pressure on network infrastructure to be faster and more capable. Initiatives like software-defined networking and protocols such as OpenFlow can make the network more flexible and manageable, but they don’t really solve the problem of application performance where high-speed, low-latency requirements are the rule. Only by removing hops and their attendant latency from the network will we continue to see performance gains. Arista’s 7124FX switch uniquely puts customer programmable FPGAs at the edge of the network for microsecond application processing.
March 16, 2012 09:00 AMAccording to the Fifth Annual State of the Network Study released by Network Instruments, 83% of IT professionals surveyed said problem number one with application management is “determining whether problems are caused by the network, the system or the application.”
March 14, 2012 09:27 AMA new study shows that companies are expanding their use of videoconferencing, but many worry that they may not be able to keep up with the network bandwidth demands of the technology. The concerns are documented in a survey that looks at three networking-related issues: video, cloud computing and application management. In the first of a three-part series, Network Computing looks at videoconferencing and the network.
March 06, 2012 01:00 PMWhile the federal government has mandated that nearly 40% (more than 800) of its data centers be consolidated by 2015, the results of at least two recent studies indicate several concerns about the implications of the consolidation. According to the Federal Data Center Consolidation Initiative (FDCCI), federal government data centers quadrupled between 1998 and 2010, from 432 to 2,094, and, on average, they have been using only 27% of their computing power. As a result, federal CIOs are looking to consolidate effectively without compromising data center management by embracing server virtualization, shifting to a "cloud-first" policy and through modular computing.
March 01, 2012 09:00 AMOne of the dirty little secrets of software as a service (SaaS) is how long it takes to get the service. A request for access to a SaaS application travels from the client device, across the corporate WAN, across the public Internet to the SaaS provider's data center where the app is hosted--and back--so a lot of time is spent making the connection, not to mention the hundreds or thousands of round trips made in just one session in which the app is being used. Application delivery platform provider Akamai Technologies has partnered with WAN optimization provider Riverbed Technology to include their technologies in each other's products to improve the performance of SaaS applications.
