Improved disaster recovery for small businesses
Big Blue is making plans to offer a disaster recovery service for smaller businesses that use network-attached storage systems, so that they can provide hot backup for every aspect of their networks.
IBM is going to offer TotalStorage NAS Gateway 500 with one-way processor configuration in order to provide a cheaper NAS environment with less-demanding performance needs.
This small business version will be scalable so that it can run one two, four or eight processors eventually.
The one-processor version will also include three types of mirroring over IP networks, such as asynchronous, synchronous and Mirror Write Consistency (MWC).
MWC writes data to the local disk at the same time as it is sent across the remote site. It is only finished when the remote site identifies the write as complete, which is thought to be faster than synchronous and more data secure than asynchronous.
The one-processor version will also still link storage area networks with the users who need access to data over IPs.
IBM hopes that this cheaper version will allow smaller customers to combine the performance and availability of SANs, with the speed and manageability of NAS'.
Big Blue hopes that some companies can use it in the data centre and at a remote office, so that files can be replicated in both, providing adequate disaster recovery. Software is also built in to help administrators remotely manage the data.
