The Al Manhal Water Factory in Saudi Arabia, a subsidiary of Nestle Waters, has installed Kemp server load balancing appliances to deliver high availability and optimised performance for its Microsoft Exchange email services. With an annual capacity of over 200 million litres of drinking water to meet the demands of some 25,000 homes and offices and 2,500 retail outlets, fast and efficient communications are critical for the smooth running of this growing business. The pair of Kemp LoadMaster LM-2200s now ensures that up to 700 Al Manhal email users are automatically connected to the best performing MS Exchange email server. And if one of the servers becomes inaccessible or is taken off-line for maintenance, the Kemp load balancers will automatically re-route users to other functioning servers so that they always get a rapid and reliable experience.
“Our dependence on email and the steady growth in network traffic meant that our Microsoft Exchange Servers were coming under increasing pressure,” explained Hossam Hassan Ahmed, Network Engineer at the Al Manhal Water Factory. “The Kemp load balancers, recommended by Microsoft, now ensure good performance and high availability for our email services and have provided us with a low-cost solution, compared to some of the other vendors we looked at such as F5.”
Like many mid-size enterprises adopting server load balancing for the first time, one of the key drivers for Al Manhal Water Factory was the changes Microsoft made to its Exchange 2010 core server architecture, including the use of Exchange Client Access Server (CAS) to handle client connections. These changes mean that Microsoft now recommends the use of additional hardware or virtual load balancing to get the best performance and reliability from its Exchange email services.
The Kemp LoadMasters are designed to get the most out of advanced messaging applications and protocols used by Exchange 2010, including Outlook Web Access, Outlook Anywhere, ActiveSync, SMTP, POP3 and IMAP and RPC Client Access (Native MAPI). In addition, processor intensive SSL encryption is also offloaded from the Client Access Server CPUs to further increase speed and performance.
“Load balancing has traditionally been viewed as only necessary for very large enterprises,
but now companies of all sizes are looking for affordable load balancing solutions to ensure optimum performance from its servers and applications – including Microsoft Exchange, SharePoint, Lync and Terminal Services, ” said Thomas Kurz, Territory Manager DACH & ME for Kemp Technologies.
“Like the water we produce, we have to keep our email flowing,” adds Hossam Hassan Ahmed. “The Kemp LoadMasters give me the reassurance that we can deliver fast and reliable email services to our staff and if one server goes down, traffic will be redirected automatically to another operating server to ensure high availability. Furthermore, the Kemp team is always on hand to provide technical support if we need it.”
