Compare Storage Systems by Alexander Thomasian, Paperback | Indigo Chapters

Storage Systems: Organization, Performance, Coding, Reliability and Their Datacovers computer storage systems with replication and erasure coding. Noted storage systems pioneer and researcher Alexander Thomasian discusses coding, reliability, and performance of popular RAID organizations: RAID1 mirrored disks, RAID5/6/7 1/2/3-disk failure tolerant - 1/2/3DFT arrays. RAID5 is analyzed in normal, degraded (with one failed disk), and rebuild mode. Clustered RAID organizations are proposals to improve RAID performance in degraded mode. Various rebuild techniques are discussed for the systematic reconstruction of a failed disk on a spare disk. Storage technologies starting with punched cards up to ash memories and beyond are discussed. Data placement and scheduling of magnetic disks is discussed, although they are being replaced with Solid State Disks (SSDs) for high performance applications. Readers will learn about the storage of files, SQL and NoSQL databases on disk and SSD to achieve higher efficiency. Data compression, deduplication, and encryption techniques for storage systems have led to new technologies and startups, as well as techniques to save power in storage and server systems. Finally, three storage prototypes discussed areFast Array of Wimpy Nodes(FAWN) at CMU, RAMCloud at Stanford, and key-value flash Lightstore at MIT, along with two storage proposals: heterogeneous disk arrays and hierarchical RAID, which are relevant to cloud computing.
