There are misconceptions about what High Availability (HA) for modern infrastructures should be based on. I predict more vendors will try to position themselves as availability leaders in the future, because it sounds really cool, and obfuscates what may be fragmented or niche product capabilities. Don’t judge the book by its cover or its marketing!
With Arcserve UDP we introduced a unique set of broad capabilities that leverage our years of expertise in High Availability. As a matter of fact, if you look closely, Arcserve UDP is uniquely differentiated by delivering true High Availability for a variety of environments. No one else does this in a unified and easy to use platform.
So why should you care? It turns out that in order to deliver a true granular level of control for RPO and RTO including zero data loss, you need to have proven HA capabilities in your technology stack. As I discussed in previous posts on this blog, the challenge is to make the technology fit in a coherent fashion with other technologies you may have in your environment in order to provide data protection or data loss mitigation. This means seamless failover and automated failback with essentially no data loss, automated non-disruptive testing, and support for virtual and physical systems to name a few. That’s where having a unified architecture is critical.
Also, leveraging hypervisor capabilities and snapshots as an alternative (we call it Virtual Standby) is a good step in the direction of HA, but it’s just a starting point.
That’s where we expect to see vendors causing confusion in the market by making what we call “Near HA” pass as the real thing. It’s just not.
The real test is not what technology you use in the background, but what results you really get. It’s about having the assurance that you can recover systems and data on the basis of business-driven Service Level Agreements.
Availability for the data center is fundamentally about orchestrating a variety of technologies to get to the only result that matters: the right RPO and RTO. We call it Assured Recovery.
