MANAGEMENT SERVICES DEPARTMENT <br /> MIS DIVISION <br /> Memorandum No. 2009-07 <br /> July 1, 2009 <br /> MEMO TO: Honorable Mayor McElroy and City Council <br /> FROM: Ryan P. McCrady, City Manager {�'� I� <br /> Gerard J. Bauer, Assistant City Manager �� , <br /> David S. Johnston, Manager, MIS Divisio ' <br /> SUBJECT: Server Infrastructure Upgrade <br /> SUMMARY RECOMMENDATION: Staff recommends that Council approve the <br /> resolution at Enclosure l., authorizing the City Manager to execute a purchase agreement <br /> with S. E. A. Group, Inc. for the purchase of a Dell EqualLogic PS6000E storage area <br /> network (SAN). <br /> BACKGROUND: Council recently approved the purchase of server virtualization <br /> software and a small number of very powerful rack-mounted servers, the master <br /> computers that host all applications, control data traffic, and provide centralized data <br /> storage for the many workstation computers on our network. These were essential first <br /> steps toward the City's-long range goal of controlling costs by consolidating servers, and <br /> will result in the replacement of as many as 11 major servers by as few as three. This <br /> purchase provides the final hardware element needed for the project, an integrated array <br /> of data storage devices, independent of the servers, but capable of serving the data <br /> requirements of any or all of them. Current City infrastructure consists of multiple <br /> dedicated storage devices contained within the server requiring the data. SAN <br /> technology provides several major advantages, all with cost-saving implications: 1) the <br /> capability for independent server upgrades without mandating the replacement of the data <br /> storage devices at the same time, 2) more efficient use of storage capacity by elimination <br /> of redundant storage requirements, 3) improved system reliability through greatly <br /> enhanced fault tolerance, due to redundant dual controller design, offering no single point <br /> of failure, 4) modular design to allow for growth when needed without affecting data <br /> availability, and 5) reduced administrative costs resulting from the automation of <br /> repetitive management tasks. <br /> The summary of quotes received is provided at Enclosure 2. Staff recommends <br /> acceptance of the proposal of the lowest cost bidder, S. E. A. Group, Inc, for $28,658.00. <br /> POTENTIAL OBJECTIONS: None anticipated. <br /> 1 <br />
