Data centre that
holds the calamity function- ** power office storage system
One
of the main electric power providers as China, **Utilities Electric
Co. offers the
electric power continually for all trades and professions of the
whole province, grasping the
electric power artery of the whole province, is undertaking the
power supply task of the whole province. The particularity of power
consumption and electric power use increased constantly, ** Electric
Co. realize that the computer system must be normal running of 7*24
hours; As soon as the key data of the marketing system of electric
power destroied, the loss will be huge and difficult to make up.
So, the fault-tolerant function of computer system is too simple
to meet the demands, what ** Electric Co. needs is the scheme that
can deal with various kinds of calamitous strikes calmly .
After
reviewing many manufacturers, finally, ** Electric Co. has chosen
the storage solution that offered by COMPAQ. The solution can resumed
the marketing system of electric power within short time even take
place under the situations of natural calamity, such as fire, thunder
and lightning and hurricane,etc..
Finally, ** power office has accepted to use MA8000 optic fibre
storage solution and DRM data duplicate manager of COMPAQ as the
data centre foundation, and realized all-sidedly that the data management
immediately and holds the calamity at different place. This scheme
is through the special-purpose optic fibre circuit, two MA8000 at
different place joined, the data of two MA8000 is guaranteed to
be totally unanimous. The computer system of ** power office can
protect those important datum and apllication system of local &
city bureau ofclass I & class II.
This solution offers the following characteristic for **The power
office:
·Backs up the online real-time continuous data of pruduce and backup
place, highly guarantee the unanimous of two place. If the calamity
takes place, DRM can guarantee that the backup can be used online
at backup place, supporting recovering the work of application system
rapidly at the backup place. These kind of recovery usually can
be finished within several minutes.
· Utilizing the
function of DRM that moving a large amount of data, ** power office
has began the application about data storing and data excavating.
Besides, utilizing DRM moving importan data out of storage subsystem
temporarily and processing system maintain, these can great reduced
the degree of difficulty and workload.
· The strong expand ability of system, support using 4, 9, 18 and
36GB UltraSCSI hard disks, the capacity of single storage subsystem
is up to 2.5 TBs, The whole long-range mirror image capacity is
more up to 10 TBs( 2.5 TBs of every subsystem, 4 stature systems
of every website); In system, most high to support every host server
joine by 6 a piece of host server buses , each storage subsystem
can support 12 host servers .
·Utilizing the funtion of DRM to write into history and rebuild
"MiniMerge", when the system breaks down, the fast recovery
of assurance data can be guaranteed too.
Online /online two-way solution
·DRM disposes some single trouble in the hardware and software package
, thus guarantee the high usability of the host server.
·Supporting clone function at the start palce and the end place,
and the function fo quickly replication at the goal place.
