In "Lisp Systems in the 1990s," Layer and Richardson explain that a Lisp system contains a programming environment with debugging tools, a storage allocation
module with a garbage collector, a compiler, an interface to foreign code (e.g., C code), and often an interface to a window system.
Like their SAN and NAS counterparts, IP-SAN offers useful and cost-saving capabilities, such as: dynamic storage allocation
(expanding storage on the fly); RAID striping and mirroring (for increased performance and reliability); snapshots (for fast backups and restores, as well as near-production development); Replication (block-level--only the changes are replicated locally and to the remote site).
The suite supports local and/or remote access by system administrators; easy setup of any standard RAID configurations without interruption of server operations; full monitoring of component health via SES and SAF-TE industry standards; full logical unit mapping for easy storage allocation
and partitioning; and a permanent database that provides means for tracking problem areas, balancing storage usage and scheduling routine maintenance.
As with memory management and e-mail, storage virtualization seeks to simplify unwieldy tasks such as setup, storage allocation
, load balancing, RAID configuration, backup, replication, and snapshots.
When combined with tiered-storage architecture to guide storage allocation
and distribution, SAN-based replication demonstrably lowers storage infrastructure TCO.
The group handles the details of storage allocation
and capacity balancing across the available physical disks and arrays.
With passwords and authentication limited to specific management nodes, ensuring physical and logical security over storage allocation
is much easier.
With virtualized storage, Server A can expand its database onto the second disk without compromising the Server B's existing storage allocation
Where storage allocation
and expansion deals with capacity growth within already existing storage, storage procurement projects future storage growth and recommends the best storage device(s) to purchase that would optimize cost and deliver the required performance.
SANenabled storage allocation
and backup software applications provide centralized capacity management.
Management software, operating with routers, provides capabilities such as stand-alone instant backup and restore, 7/24 data availability, dynamic storage allocation
, host zoning, and security.
