Intelligent Capacity Management Services (ICM)
In today’s data center
environments supported by storage virtualization, the storage system’s
ability to automatically expand the virtual disk space to accommodate file
system growth is one of the key IT requirements for continuous data center
operation.
The data center
administrator needs to provide 24x7 availability of data and adequate
storage space. Costly downtime caused by “file system full” or “out of disk
space” is to be avoided. To achieve the goals of continuous system uptime
and storage availability, the data center administrator needs access to file
system information, such as file and directory tree attributes, file system
storage usage and the underlying virtual disk partition utilization
characteristics. These are all critical information required for file system
management and virtual disk space maintenance.
With traditional small
server data growth, as new servers and disks are added to the network, users
experience interruptions in their regular service. This interruption will
have severe business impact if access to company’s data is not available
during business hours. iQstor Intelligent Capacity Management Services (ICM)
offers uninterrupted virtual storage provisioning and automatic file system
expansion. |
Features and Functions
Working
in tandem with operating system specific agents, iQstor Storage
Virtualization Services (SVS), iQstor Storage Management Services and
user-defined policies for file system size limits, ICM offers the small and
mid-size businesses a non-disruptive process to gain information about
operating system specific file systems and automate virtual disk expansion
on a file system basis. The intelligent policy-based management component of
ICM allows the data center administrator to set certain thresholds for the
file system size, as well as a set of policies for growing the file system
automatically when the threshold is reached. ICM eliminates the costly
downtime associated with re-building and re-formatting operating system
partitions due to unforeseen storage requirements. |

Reporting File System Information
ICM scans
all active Vdisk (Virtual disk) volumes and provides partition and file
system layout information through the iQstor Storage Management Software to
the IT administrator. ICM examines boot sector records and provides
information about partition tables, magic numbers, checksums and various
file system data structures that include meta-data and system files.

Recognized Partition types are:
MSDOS partition
(including DOS, Win9X, WinNT, Win2K basic disk)
SUN Partition (8
maximum)
Win2K Dynamic
Partition (up to 128 simple volumes)
|
|
Recognized file systems include:
NTFS (NT, Win2k,
and Win XP)
EXT2
UFS
VXFS 4.0

Automatic Expansion of Virtual Disk Space to Accommodate File System
Growth
ICM is a
policy-based capacity management feature which through continuous monitoring
of storage consumption, prevents the system from running out of storage
space. When a Vdisk needs to be expanded, ICM provisions more capacity from
one of the storage pools without interrupting the operation of the
application servers, eliminating costly downtime associated with traditional
physical disk upgrades.
