Rebuild mirrors up to 50-times faster
SoftRAID has introduced a new 4.0 version of its self-titled RAID software and disk management utility. Previously announced in January of last year, the upgrade offers a wide range of new features and improvements, such as 64-bit kernel support in Snow Leopard operating systems, and full compatibility for Solid State Disks (SSD). Also amongst the new changes is the ability to now rebuild mirrors approximately 50-times faster, enabling mirror rebuilds to take less than 10 minutes on 1 – 2TB volumes.
SoftRAID 4.0 demo at Expo
SoftRAID on Wednesday announced SoftRAID 4.0, a major upgrade to its RAID management software for Mac OS X. Expected to be demonstrated at MacWorld (booth 342), version 4.0 will be released by the end of Q1 2009 and will bring RAID enhancements to improve the rebuilding process -- especially on large volumes. With Fast Mirror Rebuilds, SoftRAID keeps track of which parts of the volume are used when a mirror disk is not present, and only rebuilds those sectors when the other mirror disk is reconnected. This allows users to rebuild there mirror volumes in minutes rather than hours.
SoftRAID upgrades to 3.6.7
SoftRAID has upgraded its Mac RAID software to 3.6.7, in response to compatibility problems with Leopard. The main feature of the upgrade is a new driver mechanism that stores two copies of the RAID header information. Leopard users on Intel-based Macs were experiencing occasional RAID header corruption, which led to SoftRAID engineers having to recover the volumes. The new update stores a backup copy of the header as a fallback when the software recognizes the primary has become corrupted. The corruption was occurring at a ratio of 1 in 10 million header write cycles. The update is free to version 3 owners and costs $130 for a downloaded version ($150 retail).
