Engineering Firm MCW Consultants Ltd Ramps Up File Integrity and Productivity With Packeteer(R) iShared(R) Solution

Packeteer® (NASDAQ:PKTR), the global leader in WAN application delivery, today announced that the MCW Group of Companies, a leading professional engineering services firm in Canada, has deployed iShared® appliances and iShared FlexInstall software at all of its offices throughout Canada to optimize performance in the company’s enterprise-wide virtual private network (VPN). The iShared solution has reduced file access times by a factor of 25, and now ensures integrity of the company’s large AutoCAD files by eliminating previous version control problems. The MCW Group of Companies provides Consulting Engineering Services (MCW Consultants Ltd.), Energy Management Services (MCW Custom Energy Solutions Ltd), and Power Engineering Services, (AGE Power Consultants). Because engineers at different locations routinely worked on the same project, the company operated a VPN connecting all of its offices. To deliver acceptable levels of performance, many of the larger AutoCAD files were replicated via the VPN to local servers. But the inability to coordinate updates to multiple versions of the same file caused version control and data corruption problems. "What we needed was a distributed file system that would seamlessly extend the datacenter out to all offices,” explained Shawn Marten, IT manager at MCW. "As a complete ‘remote office in a box,’ the iShared solution is perfect for this purpose. With iShared’s approach that is based on single-instance storage with application-intelligent caching, we no longer need to make any tradeoffs between file integrity and user productivity.” iShared’s Wide Area File Services (WAFS) technology provides real-time, read-write access for both the Common Internet File System (CIFS) and the Network File System (NFS) via the WAN. iShared’s WAFS is a true distributed file system that combines file integrity features, such as read-ahead and file differencing, with intelligent WAN bandwidth optimization features, including branch office caching, TCP acceleration and data reduction through wide-dictionary compression. To fully optimize WAN bandwidth utilization, only the changes in a file — and not entire files — are transmitted. iShared’s file differencing technique also incorporates sophisticated journaling and recovery provisions to maintain full availability and transparency for file read/write operations during WAN disruptions and outages. iShared’s file performance optimization and acceleration technology is also a key component in Packeteer’s iShaper product which adds to these features with best-in-class application classification, visibility and QoS to create the industry’s first unified branch office appliance. "As soon as we installed the iShared solution, there was an immediate and significant improvement in performance,” Marten said. "An AutoCAD file that used to take a minute to download across the VPN, now loads in about two seconds. This has not only improved the productivity of our engineers, but it has also eliminated the complaints the IT department used to get concerning poor performance.” The MCW Group of Companies is using a mix of iShared appliances and iShared FlexInstall software. The datacenter and the three largest offices are each equipped with a model IS 300 appliance; one other office has a model IS 100 appliance. The remaining offices utilize iShared FlexInstall software, which is installed on existing Microsoft Windows 2003 servers. "Both the appliances and the software were very easy to install and configure; just fill in the blanks and it runs great,” Marten added. "As MCW Group of Companies continues to grow and provide engineering services across Canada, the IT department will deliver IT solutions that will address WAN performance concerns and enable synergy among all offices,” said Alex Rodas, senior IT manager at MCW. "The Packeteer iShared solution has become part of the overall network improvements that will enable us to meet our strategic plans and produce a solid network.” About MCW Group of Companies of Companies Since 1964 the MCW Group of Companies http://www.mcw.com has built a solid reputation for the delivery of Professional Consulting Engineering Services, Energy Management Services and Engineering Development Services.
