The server also has an embedded journaling file system
for simpler administration--an important consideration, since studies have shown that while every megabyte of storage added to a server costs less than 60 cents to purchase, it incurs an additional $3.5 per year in labor and lost productivity to manage.
As far as SCO is concerned, this means technologies such as the AIX Journaling File System
, the AIX Enterprise Volume Management System, and the Dynix Remove Copy Update should be treated as part of the original Unix System V code, and therefore should not have been donated to Linux.
"Quick Restore complements 9205 NAS features designed for maximum reliability and minimal downtime, such as the ext3 journaling file system
, RAID 5, and easy installation and management."
This is not to say that the company doesn't offer prod-ucts in other areas; indeed, through much of the '90s, some observers might say that the company almost lost sight of its strengths, allowing itself to be drawn into the general-purpose Unix server wars--where it has been thoroughly trounced by Sun and HP and then into the world of Windows servers--the very definition of a me-too, commodity market and, now, SGI is an enthusiastic player in the open-source Unix world, as well, and has made valuable contributions to Linux, includeing the company's XFS journaling file system
, which addressed a serious weakness in Linux.
