DISK_PAK OnLine! for UNIX

UNIX file systems truly do fragment

File systems fragment throughout your daily operations. Every time a file is created, deleted, or changed, portions of that file may scatter across the file system.

DISK_PAK for UNIX optimizes the file system,

putting all elements of each file together;
grouping available space; and
clustering heavily accessed files.

Each of these steps allows the read/write heads to access data quicker. Since moving the heads is the most time-consuming activity when accessing your file systems, DISK_PAK for UNIX provides peak system responsiveness.

New with DISK_PAK OnLine!

An enhanced version of EAGLE's flagship product, DISK_PAK, DISK_PAK OnLine! offers these additional features:

File systems don't have to be unmounted to be reorganized
Users can access data during the on-line optimization process
Automatic File Placement (AFP), which clusters the most frequently accessed files, speeds up disk I/O and reduces seek distances
The product is transparent to the users; users not affected during reorganization
Disk monitor capabilities allow system administators to actively monitor disk performance
Network capabilities allow centralized disk management on the entire network
The root file system can now be optimized

A tried and true defragmenter

Defragmenting file systems with DISK_PAK OnLine! provides you with a number of measurable benefits. In addition to the new features, DISK_PAK OnLine!:

Defragments the file system in place without operator assistance
Reduces user complaints due to slow system response
Makes UNIX data caching more efficient
Has several user-selectable parameters, providing a truly "customized" optimization of each file system
Supports RAID disk subsystems and third-party drives
Operates with interactive or non-interactive (batch) execution
Has an OSF/Motif user interface
Can do multiple scans and organizes simultaneously
Allows scans and organizes to be interrupted during any phase of the process

DISK_PAK OnLine! fixes access and space fragmentation which dumping and reloading cannot! Access fragmentation is when two heavily accessed files are placed at different locations on the file system. Space fragmentation is caused when available space is scattered throughout the file system.

Seeing is believing

You may obtain a Disk Fragmentation Analysis Kit from EAGLE that contains read-only software which illustrates the degree of fragmentation on your system. We recommend using this analysis tool frequently, tracking how quickly fragmentation occurs. The analysis software reports statistics on available space, degree of fragmentation, and number of contiguous directories and files in each file system. Click on the link and try it for FREE!

DISK_MONITOR

An important part of DISK_PAK OnLine! is the DISK_MONITOR utility, offering system managers a unique graphic of the need for and the effects of the optimization done by DISK_PAK OnLine! DISK_MONITOR includes a histogram to graphically show where accesses are occurring on the file system and how fragmented those accesses are across the file system. Fragmented accesses translate into high seek distance, which greatly hinders system performance.

Safe and secure

Each new revision of DISK_PAK for UNIX goes through extensive testing by the EAGLE technical staff. EAGLE has even gone so far as to literally pull the plug when our file system is organizing, and not one piece of data was lost. At any given time during optimization, there are actually two copies of the information DISK_PAK is working on, so if the power dies or some other physical problem occurs within your system, your data will be safe.
