Choosing Network-Attached Storage for VMware: What You Should Know
VMware users have three choices when selecting a storage protocol: Fibre Channel (FC), Internet SCSI (iSCSI), and Network File System (NFS). This research note suggests that while vendors tend to market their products based on their strengths and interests, users need to look at different variables to determine what is in their best interests. Included are 5 key findings and 2 important recommendations. Length: 3 pages » |

Measurement and Analysis of Large-Scale Network File System Workloads
This study presents the analysis of CIFS traffic deployed in the NetApp data center for a three-month period, representing over 22TB of storage used by 1500 employees. The study finds that workloads were quite different from those previously studied, showing that modern file system workload has changed in the past 5–10 years. This change has implications on the future design of network file systems, which is described in the paper. Length: 14 pages

A Highly Accurate Method for Assessing the Reliability of Redundant Arrays of Inexpensive Disks
RAID storage has achieved widespread adoption since the late 1980’s, but IT organizations have been challenged at accurately assessing reliability. This reprint from IEEE Transactions on Computers contends that the mean time-to data-loss (MTTDL) and Markov models for predicting RAID reliability are highly inaccurate, and proposes a new model with considerably higher accuracy.
