Solutions > Performance and Availability
Prior to centralized storage, an outage on an individual disk impacted only a single application or server. Ninety-nine percent availability was acceptable. But with centralized storage, the loss of the SAN impacts the entire organization. One hundred percent availability must be the standard.
But how do you increase availability further? Operating procedures, high-quality equipment and operator training can only go so far.
SANscreen offers a solution. Most outages that occur in the SAN are not the result of a single action, but of multiple events that occur in a sequence. These latent quality issues can build up over time – days, weeks, or months – as the SAN is configured and changed. The key is to uncover and find these issues before they build into a critical mass that causes an outage.
SANscreen detects various levels of service quality violations and vulnerabilities in the storage environment. Storage managers can track their overall SAN health at any given point in time, then prioritize and fix the most serious service violations.
SANscreen goes beyond just reporting on the current state of service violations in the environment. Using the ability to simulate the impact of device-level change on service levels, SANscreen can also help to prevent the introduction of service violations that occur as a result of configuration changes.
