IP/FC SAN
HyperMirror/S (Synchronous Mirroring)
The primary LUN receives the write request of the
production host, and then the data is simultaneously written onto the primary LUN and secondary LUN. If the data is successfully written
write request is processed successfully. HyperMirror/A (Asynchronous MIrroring)
The primary LUN receives the write request of the
production host, and when the data is successfully written onto the primary LUN, the primary LUN immediately returns the successful write request to the host.
The system automatically synchronizes the
incremental data of the primary LUN onto the secondary LUN at the synchronization interval. Before the synchronization, snapshots of the data
generated to avoid data on the secondary LUN from being damaged by synchronization abnormalities.

HyperImage Operating Principles
Basic Operating Principles
Before activating HyperImage, you need to create a
snapshot resource pool and then select a source LUN.
After activating HyperImage, the system creates a
mapping table that records the mapping relation of the data on the source LUN.
When a new data needs to be written onto the source
LUN, the original data on the source LUN is firstly transmitted onto the resource LUN and the mapping table is modified simultaneously, and then the new data is written onto the source LUN. The copy-on-write technology is applied in this procedure.
When another new data needs to be written onto the
same location on the source LUN, the current data is not transmitted onto the resource LUN but overwritten by the new data.
You can instantly recover the data at the snapshot point in
time through the snapshot rollback.

Operating Principles of Full HyperCopy
Full HyperCopy means to copy all the data on
the source LUN to the target LUN.
Full HyperCopy should be implemented offline. If
the source LUN receives write requests during the copy process, data on the target LUN may become inconsistent in time with that on the source LUN; therefore, the write requests to the source LUN should be paused during the copy process. Operating Principles of Incremental HyperCopy
The data on the source LUN and that on the
target LUN are initially synchronized when HyperCopy is started for the first time.
When new data is written onto the source LUN,
the incremental data amount is recorded. When HyperCopy is started again, the system copies
The incremental data overwrites the data on the
target LUN and becomes the new synchronized data.

Integration of FC and IP The S2600 integrates the technologies
GE data-processing chip and FC data- processing chip to process data from the IP and FC networks. The S2600 also supports the FC SAN and IP SAN. Integration of SAS and SATA The S2600 supports the mixing of SAS and SATA disks. SAS or SATA disks can be chosen according to the service requirements. Application: For database and mail applications, you can use SAS disks in the FC SAN. For web and video applications, you can use SATA disks in the IP SAN.

Create and use instantly After RAID groups and LUNs are created, they can be allocated to hosts instantly without waiting for initial time. The initialization of RAID groups is performed in the background, thus shortening installation time. Online expansion To increase storage capacity, you can add expander enclosures and disks online to expand RAID groups and LUNs. The capacity can be expanded in real time without interrupting services. Powerful expandability The S2600 supports a maximum of 96 disks with a maximum capacity of 96 TB when 1 TB disks are used. It supports 256 host and 512 LUNs to meet increasing requirements on capacities.
