Calculating Usable Space on a ZFSSA [24753]
A How-to Guide to Using Ryan Mathew's Size Calculator
The proper use of Ryan Mathew's Size Calculator in determining storage pool allocation is the subject of a blog by Steve Tunstall, who writes that the calculator will provide details on such questions as which type of pool to make; will more than one pool at a time work on a system; and how much usable space will you be left with when the pool(s) are installed. According to Tunstall, one need only enter the number of available disk trays and their size, the number of pools desired, and the calculator delivers both the figures and a graphical layout of the tray.

ZFS for the Mac: Now in Beta [24023]
Coming Soon from Ten's Complement
Mac users would really not have had any compelling reason to inform themselves about ZFS ... until now, suggests Robin Harris in his blog "ZFS/Mac Coming Soon" where he reports that the company Ten's Complement is developing a ZFS release for Mac that is due out in a server-grade version later in 2011. So what is ZFS? Harris includes a brief but adequate description of ZFS in which he writes, "Its tree structured checksums eliminate most of the bit rot that afflicts Macs and PCs. When ZFS retrieves your data, you can be sure it is your data, and not the misbegotten spawn of a driver burp. Add a disk drive to ZFS and it simply joins the pool of blocks available for storage. You dont have to manage another disk. Cheap snapshots: roll your file system back to any point in time - like before you downloaded a malicious pdf - with almost no overhead. Fast, cheap RAID. ZFS implements very fast RAID that fixes the performance knock-off against software RAID. In ZFS all writes are the fastest kind: full stripe writes, running on the fastest processor in your system (your Mac), rather than some 3 year old microcontroller. Every time you add a disk to your Mac you see another disk volume on the desktop. ZFS eliminates the whole volume concept. Add a disk or five to your system and it joins your storage pool. More capacity. Not more management." In a word, "Neat!"

Tiered Storage Takes Center Stage: White Paper by Fred Moore of Horison Inc. [23895]
And Reduces Acquisition and Operating Costs as Well
The central assertion of the white paper "Tiered Storage Takes Center Stage" by Fred Moore is, "Tiered storage, as a storage initiative, has been proven to significantly reduce acquisition and operating costs for medium and large scale storage enterprises." He supports this contention by citing the costs for a 100 TB capacity two-tiered, all-disk implementation at $765,000 versus $359,250 for a three-tiered implementation using tape for tier 3 archival data. This economic advantage increases, Moore continues, as the storage pool itself enlarges. The overall savings from the three-tiered implementation stem from a reductions in purchase price, monthly license fees and maintenance costs and a freeing up of storage administrators to address more critical tasks. Moore sums up his argument with the statement that, "A multi-tiered storage system with automated data management provides the optimal solution for managing the 21st century data explosion."
