Report to Lead Member on the Proposed Network Upgrade and Replacement Storage Area Network This report provides an overview of the proposed upgrade to the Council’s core Network and the replacement of the Council’s Storage Area Networks. Core IP Network The Network provides communications services for Data, Video and Voice across the Council. The current network, implemented in 1999 was specifically installed to meet the year 2000 compliance and support new Corporate systems such as SAP and Email. The Network that was implemented used the latest technology available at that time which allowed the transportation of differing types of traffic over a single infrastructure i.e. Voice, Video and Data. Storage Area Network Storage Area Networks (hereafter SANs) are a highly available centralised storage solution, which improves applications performance allowing virtually uninterruptible access to data. Server backups and restores can be performed quickly and additional Disaster Recovery solutions. SANs allow the Council’s Server storage to be managed more efficiently and effectively across the Council’s Data Centres. The Council currently has Six SANs located in each of the Council’s Data Centres. There are two Data Centres located on the Civic Centre campus and one at each of the four Network Nodal Sites strategically located across the City. These were initially implemented as part of the Education ICT Infrastructure project, however the number of applications using the SANs for the storage of Data has increased significantly to include the following: Email File Storage CRM ICLipse Document Imaging Obtree Web Site Content Management System Caching Service for Internet Access Business Rates System Norwell Legal System Education Management System All Windows based servers are now using the SANs for the purpose of backing up data to tape for Disaster Recovery and Audit purposes. Most medium to large scale Windows based Server Applications utilise the SANs for the storage of data, the SAN is therefore classified as a Business Critical Service. The Case for Change This section sets out the reasons why these two critical technologies need to be considered for replacement. Core IP Network The current core network is mainly leased on an operating lease, which expires in December this year and all equipment on the lease will be returned. Network technology has developed significantly during this period, combined networks were just being developed in 1999 and therefore the solution that has been implemented at the Council is complex, proprietary and difficult to upgrade. With the end of the lease of the equipment this year it is proposed that the Council replace the core network with a new design, which will give the Council more flexibility, availability and capacity. Storage Area Network All six SANs were implemented during November 2001. The SANs had a combined Storage capacity of 4.6TeraBytes (4,600 GigaBytes) of Hard Disk space, this has grown in less than two years to 11TB (11,000GB). The SAN also has up to 86.4TB (86,400GB) of offline Storage using tapes for backing up servers. Unfortunately shortly after the SANs were deployed by Dell within the Council they announced that they would be ceasing production of their own SAN equipment within 12 months. Dell signed a joint partnership agreement with EMC to develop and manufacture SAN equipment, EMC are the market leader for SAN equipment and software. There are two major implications for the Council, development and support of the SAN. The Storage requirements of the Council are currently increasing by 50% each year, the current Dell SAN has exhausted its capacity. A small Dell EMC SAN has been purchase to allow continued growth. It is not possible for an existing Dell SAN to integrate with a new Dell EMC SAN, therefore separate SANs have been implemented. The support agreement with Dell will expire in November 2004, it will be costly to extend this support for future years and will be impossible to have support beyond 2006. Proposals This section sets out the proposed changes to the Network and SANs Core IP Network The Council’s preferred Network supplier has been approached to provide a design, which meets the Council’s current requirements for Network services and those likely requirements for the next five years. The supplier has provided the Council with a network design and kit list, which in our opinion meets these requirements whilst reducing the financial impact on the Council. The Core of the Network will be changed to a different technology, which is also capable of transmitting Voice, Video and Data over the same Infrastructure. The new network includes greater resilience and manageability through the simplification of the design and the use of industry standard protocols. Storage Area Network It is proposed to replace the current Dell SANs with a new Dell EMC SAN located at the Civic Centre incorporating the equipment already purchased. Desktop Services are currently designing this replacement SAN with Dell and EMC. The main advantages of new Dell EMC Storage Area Networks are: Enterprise Class Products from industry leader Guaranteed minimum 5 year development life of equipment Improved performance Increased Saleability Improved Disaster Recovery facilities Reduction in medium to long term costs Existing products which have been developed for the last ten years The improved performance will have a direct reflection on the speed of access to data held on the SANs. This will improve the speed of the applications listed above which will allow users to work more efficiently. The new disaster recovery facilities will provide increased protection from disasters allowing data to be recovered quickly and from reduced time intervals. The EMC solution will give increased flexibility allowing capacity to be moved from one system to another allowing increased management and reducing ongoing costs by limiting the amount of spare redundant capacity. Financial Information The current lease payments for the Network are £195K per annum. The cost of the equipment for the Network upgrade will be £300K The cost of the equipment for the SAN replacement will be no more than £300K The cost of this equipment on a lease for five years will be no more than £145K per annum, a reduction of £50K per year from the current lease payments The expected installation costs for both projects are no more than £75K. Maintenance charges and circuit charges will be no more than the current budgets, details on these costs are still being evaluated. Recommendations Lead Members are asked to approve these proposals, for the equipment to be purchased through the Framework Agreements that the Authority has with each of the suppliers and for the orders to be raised ASAP to allow the equipment to be installed before the December deadline.
