With the continuous development of storage technologies, storage
virtualization technologies and solutions for its truly open, stand out
in a number of IT technology. Under the virtual storage environment,
storage right users will become transparent, the user can Bubiguanxin
difference in function between storage devices, Rong Liang size,
equipment type and Zhizao business Ruhe, all of the equipment will be
managed centrally to give a unified function of Ru Flash copy, such as
remote disaster recovery. Today, storage virtualization is no longer a
strange word, more and more enterprises begin to focus storage
virtualization, while its implementation to the IT planning.
As
an active advocate of open technologies, IBM has been working for
decades the development of virtualization technology, a mature
technology and rich product set multiple virtual storage milestone. IBM
Total Storage SAN Volume Controller (SAN Volume Controller hereinafter
referred to as SVC) and IBM Total Storage SAN File System (SAN file
controller hereinafter referred to as SFS) with its superior performance
to the storage industry to bring revolutionary change, contribute to
the system integration, better sharing and use of data through the
system simplifies storage management significantly reduced the number of
points and servers.
SVC: elimination of storage boundaries
At
present, the face of fierce market competition, any data loss and
operational interruptions are business can not tolerate. However, due to
historical reasons, the traditional SAN network, each storage systems
are self-contained. Complex storage infrastructures, many different
brands of storage virtualization products, not only bring a lot of
negative daily storage management, and more difficult to do without
affecting the application of the premise, data migration, change or
upgrade storage.
In response to these needs, IBM believes that
virtual storage with the storage environment, simplify the complex,
heterogeneous platform to eliminate transmission of information caused
by the barrier, enables on-demand storage system, distribution according
to need to store truly is the best solution. Based on this, IBM's SVC
is the entire SAN network controller, the entire SAN in a variety of
storage devices into one large storage pool, full use of storage
resources and allocates storage space, performance and functionality.
In
many conventional SAN disk arrays, the data copy operation is limited
storage within or between the same disk. However, virtual SAN, since the
SVC is a completely open design of the storage environment, compatible
with a variety of storage devices. Users can integrate a variety of
storage solutions including, without worrying about what SVC closed. SVC
allows the user to different suppliers across multiple storage
subsystems to use a single high-level copy services, such as FlashCopy
and remote copy MetroMirror. The software can be achieved by extending
the support of all current non-IBM disk storage systems, virtual and
manage these systems to help customers simplify the view through the
central management of heterogeneous storage environment and implement
management automation.
SVC control functions will be centralized
storage to the storage network platform of unity can be achieved. And
unified SAN file system can be concentrated on the realization of file
sharing among different platforms and data lifecycle management. Based
on open, centralized device management tools to implement resource
management and policy-based automation, and network management through
the SAN, backup / restore and storage resource management storage
management software. In addition, SVC has achieved virtual storage layer
(VirtualizationLayer) function, will be added to the SAN storage
intelligence network.
Now the user can follow the changing needs
of applications to allocate storage, but no longer subject to storage
subsystem device functionality and performance limitations. SVC is the
center of a SAN network management control point, and its server
operating system and storage subsystem transparent. The ability to truly
help customers realize heterogeneous disaster recovery environment.
As
a pioneer in the field of storage virtualization, IBM SVC to address
heterogeneous storage environments for information sharing, disaster
backup is the most technical content and the most sophisticated virtual
instruments, creating a very far-reaching impact. So far IBM has helped
more than 1,000 clients worldwide through virtual technology to simplify
the IT infrastructure. Today, IBM Corporation to existing technology,
based on new SVC3.1 version, will greatly enhance the performance of
virtualization, while scalability and interoperability has been further
improved, and thus be able to manage larger and more diverse
environment, the version of the 1024 hosts can also manage and support
all major host and operating system performance greatly. Cache capacity
than doubling the previous version, be extended to 8GB.
SFS: to
open so simple
As the use of virtual storage technology into the
simple storage of active practitioners, IBM virtualization technologies
in a proven track record of research, breakthrough technology in the
creation of SVC storage industry at the same time, the SFS will enable
those in the open systems environment, management of corporate data
assets and data storage resources in the way of revolutionary change.
SFS
for the open system environment into an innovative, cost-effective and
efficient model. Among them, the company's data assets and data storage
resources owned by the business sector does not depend on the platform
for enterprise management of public facilities. This model has the
advantage of physical data storage and data management and use of
equipment and segregated. Because public facilities are the virtual
storage system management of storage resources to create, customers can
achieve freedom Xuanze and those most suited to their application needs
of Shujucunchu 业务 virtualization technology.
Very similar with
the SVC, SFS is installed in the SAN file system, but also a combination
of hardware and software products. It's operating system platform for a
variety of Bu Tong provides a unified file storage environment, 将 more
independent of the file Xitong abstract as a Gongxiang file system,
which resolved Chuantong SAN Jiagou in documents and data management
issues, Shi Xian file-level data sharing, storage, distribution and
Serverless data backup, and the same with SVC, it also has a strategy to
dynamically adjust according to storage device configuration, and
transparent migration of data storage virtualization SAN controller
functions, all functions around the document aims to level of storage
service launched.
Not only that, SFS distributed file system in
turn design concepts and system architecture a step forward. Their
addition to the general characteristics of the distributed file system
but also the entire file system using SAN as the data storage and
transmission path. They use-of-band (out-of-band) structure, the file
system of the original data in high-speed Ethernet transmission, from
the original data server specifically to handle and store. SAN File
System uses policy-based file data location selection methods, effective
use of system resources, improve performance and reduce costs.
Enhance
the value of a comprehensive storage
IBM's storage
virtualization technology is to promote changes in the industry, IBM
offers the industry's most comprehensive storage virtualization
capabilities, from software, disk to tape solution that provides end to
end approach is the overall system to achieve each level of the virtual
and real open.
Currently, customers around the world are using
IBM's virtual storage technology. IBM storage virtualization solution
supports open standards, can be unified management of various storage
devices vendors, breaking the storage vendors has always been an
exclusive product of the barrier. And as the business of data growth,
you can always replace aging equipment or to add new the equipment,
without affecting the proper operation, Guan Liyuan as in the past
without Zai Zai night Suoyou business are Tingzhi the request to be
Kaizhangongzuo.
In the virtual environment, all of the storage
management operations, such as system upgrades, establishment and
distribution of the virtual disk, change RAID levels, storage space can
be expanded automatically to a simple storage management easier.
Therefore, companies need to open a virtual storage solution to build a
truly open storage environments, by managing the complexities of the
underlying storage environment, storage virtualization can help simplify
the infrastructure, and then use such information across the enterprise
to create a single virtual pool of such technology to help companies
significantly reduce IT management costs. Storage virtualization-based
solution is IBM's Information On Demand strategy, the main Zuchengbufen,
