Oklahoma-headquartered oil and gas wholesaler Jim Woods Marketing (JWM) has deployed ‘virtual network accelerator’ technology from Expand Networks of Slough, UK. Jim Woods has virtualized applications at its data center with VMWare and is now leveraging Expand’s WAN Optimization technology to enhance performance. JWM uses a bandwidth intensive logistics application whose performance was downgraded following virtualization.
JWM IT director, John Parnell, said, ‘With the virtualization project holding the business data over 100 miles away, WAN users were faced with latency and congestion challenges that compromised business efficiency. Bandwidth was inconsistent and choppy and application performance was sub-optimal.’ JWM compared Expand with Riverbed’s accelerators before selecting Expand for its capability, cost and low TCO.
Expand’s Virtual Accelerator uses byte-level caching and dynamic compression to optimize bandwidth. ‘Layer 7’ quality of service has also enhanced JWM’s SIP phone VoIP calls, which were previously prone to packet loss and jitter. Parnell concluded ‘The Accelerator has significantly improved user productivity and business efficiency at the company. Expand is delivering four times the bandwidth on the same infrastructure.’ More from www.expand.com.
