Consolidation Solutions
Beginning with the desire to consolidate storage disks into
storage arrays, consolidation is taking place everywhere in the
data center: physical server consolidation enabled by advances in
virtualization technologies, consolidation of smaller Storage Area
Networks (SANs) into a single larger SAN, and consolidation of
block and file data at a central corporate data center.
Driving IT Efficiencies
Rapid changes in hardware, technology, and capacity demands are
forcing enterprises to implement ongoing server and storage
consolidation and data migration strategies to optimize available
storage assets. Consolidating widely distributed or underutilized
resource into centrally managed environments, or migrating data,
are no longer point-in-time projects for administrators.
There are impressive technical and business advantages to
consolidation in the data center. A SAN infrastructure enables
any-to-any connectivity between heterogeneous server and storage
systems. This allows much more efficient use of storage and server
resources by consolidating widely distributed or underutilized
resource into centrally managed environments to:
- Increase storage utilization by lowering allocation for
headroom-unused storage that will be used within one to two
years
- Decrease storage capital expenditures by enabling the purchase
of storage on an "as-needed" basis
- Increase administrative staff productivity and be able to
manage more storage with fewer personnel
- Reduce application downtime and minimize business impact for
storage upgrades
- Create a centralized network environment for storage and server
platforms
A More Robust Business Solution
Traditionally, organizations have paired storage resources with
specific servers, primarily because of technical restrictions. This
implementation results in poor utilization of storage resources
because the storage is dedicated to each server and not shared
among servers. For example, free disk space on one server's disk
subsystem cannot be used by other storage-constrained servers.
This paired server-device model has proven to be especially
inflexible during periods of expansion. Simply adding more
resources as requirements grow typically results in a very
difficult environment to manage and poor utilization of resources.
In addition, when organizations have to buy a greater number of
servers and storage devices, they tend to choose less expensive,
slower, and less reliable ones.
SANs provide unprecedented flexibility for storage
environments-changing the way storage resources can be purchased
and managed. By enabling any-to-any server and storage connectivity
via switches, SANs decouple dedicated devices and enable storage
resource sharing. This cost-effective open systems approach enables
the selection of best-of-breed heterogeneous.
Data Center Infrastructure
Over the past few years, the number of server, device, and Fibre
Channel SAN ports in data centers has skyrocketed-growing by a
factor of 10 to 100, or even more. At the same time, Fibre Channel
data rates have increased from 1 Gbit/sec to 8 Gbit/sec. This
dramatic growth in both the size and speed of data center
infrastructures has turned cable management into a large and
growing problem for many organizations. Troubleshooting and
reconfiguration with traditional cabling is often difficult and
time-consuming. Scalability is also problematic, resulting in
inefficiency and increased costs. In order to fully leverage the
increased bandwidth, performance, and advanced management
capabilities of industry-leading technology, a structured cabling
solution can be customized for each unique environment.
