Open-E DSS V7
When it comes to storage systems, in today’s competitive market, industries expect trustworthy solutions which will ensure safety of their business in case of any disaster.
Even short periods of downtime in the storage infrastructure will cost company’s money, reputation and can get into possible legal repercussions. Moreover, in some industry sectors, there are new regulations in place that persuade enterprises to follow specific HA requirements.
High Availability clusters are built of a redundant hardware - typical setup is a two-node cluster in an automatic failover configuration. An example of interface protocol which can be used for this purpose is iSCSI.
Using the same storage resources, you can improve their overall performance by applying specific configuration of cluster nodes – e.g. Active-Active or Active-Passive setups.
The main difference between them is the way they process workload and utilize available storage resources. In Active-Active setup, all resources are in use - handling I/O traffic. With Active-Passive setup however, part of storage resources is in a standby mode – only being operational when disruption takes place.
