All you need to know about Storage Area Networks
The amount of data of an average company doubles every year.Thus, companies who own 1TB of data today will own 32TB in fiveyears. Storage networks help to tame such data quantities and tomanage this data growth efficiently. Since stored data andinformation are the biggest asset of any company, anyone who isinvolved in the planning or the operation of IT systems requires abasic knowledge of the principle and the use of storagenetworks.
Storage Networks Explained covers thefundaments, techniques and functions of storage networks such asdisk subsystems, Fibre Channel SAN, Internet SCSI (iSCSI), FibreChannel over Ethernet (FCoE), Network Attached Storage (NAS), filesystems, and storage virtualization. Furthermore the authorsdescribe the use of these techniques and how they are designed toachieve high-availability, flexibility, and scalability of data andapplications. Additional attention is given to network backup andthe management of storage networks. Written by leading experts inthe field, this book on storage area networks is updated and fullyrevised.
This book provides system administrators and systemarchitects, as well as students and decision makers, with the toolsneeded for optimal selection and cost-effective use of storagenetworks.
The Linux Journal awarded the first edition with the“Editor’s Choice Award 2005” in the category“System Administration Book.”
- Presents the basic concepts of storage networks, such as I/Otechniques, disk subsystems, virtualization, NAS and SAN filesystems
- Covers the design of storage networks which provide flexible,highly-available, and scaleable IT systems
- Explains the use of storage networks for data sharing, dataprotection, and digital archiving
- Discusses management of storage networks using SNMP, SMI-S, andIEEE 1244
About the Author
The authors are employed at IBM’s storage competence centerin Mainz, Germany. They work at the interface between technologyand customers. Their duties cover a wide field of responsibilities.They develop and test new software for storage networks. Theypresent the latest hardware and software products in the field ofstorage networks to customers and explain their underlyingconcepts. Last but not least they deploy and support respectivehardware and software in customer environments.Ulf Troppens
