Virtualisation relief for peak processing periods
Virtualisation relief for peak processing periods
Jul 12, 2005: Hitachi Data Systems has extended its virtualisation products for the enterprise to the midrange and SMB companies to the ease the stress of storage and performance when systems are at their peak.
According to Hitachi, The new TagmaStore Network Storage Controller model NSC55, delivers all of the functionality of the TagmaStore Universal Storage Platform.
This includes its parallel crossbar switch architecture for high availability and performance; large-scale controller virtualisation layer for ease-of-management; logical partitioning for application quality-of-service; and the storage-agnostic universal replication for business continuance.
Tim Smith, HDS' marketing manager, ANZ, used the analogy of legs to make his point about how valuable he believes the system will be to companies.
"If you can imagine it is like having a pair of legs. If you are sitting down, they are redundant, but if you lost them, then you can't do anything with them. The new NSC55 system allows the user to make use of the redundant legs. It uses them when they are needed. But without NSC55, you might as well not have those legs at your disposal.
"It allows the user to automatically select more storage resources needed for high-powered transactions when it needs the storage, but then return back to lesser storage resources when the peaks are over.
"For instance, a data warehouse application might do 200 transactions a day, however there might be an increase spike in transactions during the middle of the month. The system can dynamically move to a higher storage system just for that period of time to help all the applications cope with the peak period."
Smith outlined that the systems work to meet the median storage capacity, so that it meets draws on resources not used in the troughs and applies them to the peaks, when they are most needed to keep the systems running smoothly. This means that the users do not see any slowing down in performance and minimises failures.
