Did you ever have a visitor to your data center say, “I didn’t know any of these systems were still around?” The implication here is that your data center is one step away from being a museum. Having “museum worthy” systems is not a badge of honor. It means that the systems in the data center are probably not delivering optimal value.
For a storage system, this can be especially bad. Disk systems are typically in use no longer than five years. There’s good reason for these systems to have a limited lifespan. They are electro-mechanical devices that wear out when in constant usage.
