Business-critical applications requires high level of performance, availability, security and scalability.
So, a new breed of storage solutions known as an intelligent storage system has evolved
These systems has an RAID arrays which controls the management, allocation & utilization of storage resources.
These systems has a cache with large amount of memory.
Components of Intelligent storage system
It consist of four component such as
Front-end:
It provides the interface between the storage system & the host.
It consist of two components front-end ports & front-end controllers.
Front-end ports enable hosts to connect to the intelligent storage system
Front-end controllers- route data to & from cache via the internal data bus using command queuing algorithm first in first out, seek time optimization and access time optimization
Cache:
This component enhances the I/O performance in an intelligent storage system.
It improves storage system performance by isolating hosts from the mechanical delays associated with physical disks.
Accessing data from cache takes less than a millisecond.
Back end
It provides the interface between cache & physical disks
The back end controls data transfers between cache & the physical disks, from cache data is sent to the back end & then routed to the destination disk
For high data protection & availability, storage systems, are configured with dual controllers with multiple ports.
Physical disks:
It stores data persistently
Disks are connected to the back end with either SCSI or FC interface
