Saga designed end-to-end FCoE solution for Erste Bank. That means that all the traffic from the server to the storage are sent via FCoE infrastructure based on the converged network adapters (CNA) in the server, a Cisco Nexus switch and a NetApp storage. New solution allows all users, from any point in network, to see server disks using the FCoE infrastructure.
Advantages of IT consolidation with FCoE standard, especially in data centers that had invested a lot in FC infrastructure, can first be seen through decrease of equipment that needs to be managed. Data Center Bridging (DCB) Ethernet add-ons are implemented to enable the traditional LAN and to allow FCoE to share the same cables to transfer data. This solution supports NFS, CIFS, iSCSI and LAN standards. DCB also enables defining priority traffic. In that way FCoE can have higher priority, while the applications that can work with variable data transfer have lower priority. And during heavy data transfer loads it is possible to stop the traffic with lower priority and allow only higher priority traffic and operations that can't be delayed.
Why should companies implement FCoE standard? One of the more important reasons is to cut cost. Analysis showed that FCoE is more cost-effective than IP and FC technologies together. This solution is easier to manage and maintain, because the company doesn't need different people for different technologies: one person can manage FCoE infrastructure. Initial investment isn't half the price of IP and FC initial investment together, but in the long run, looking at the number of people that are needed in the IT department, and the more efficient management, implementing FCoE is more cost-effective and financial benefits can be measured.
Unified storage is the idea of one architecture that combines the advantages of NAS and SAN solutions, while providing better data center efficiency. Latest generation of unified storage saves money by reducing necessary space, and using about 50% less energy for power and cooling. When looking at the active usage of some of the typical applications (Oracle, SAP, Exchange, file services, archiving, and VMware), NetApp storage implemented in this solutions has 30 to 55% less TCO than competitors' products.
