Outages happen; big horrible nasty outages happen. In a career which now spans over twenty years, I’ve been involved with probably half a dozen; from PDUs catching fire due to overload to failed air-conditioning to wrong application of the EPO*.

Vaulting on EMC Symmetrix V-Max Systems

In this blog post we will cover the Vaulting technology related to the EMC Symmetrix V-Max and the DMX-4 technology. Vaulting is a key feature added on DMX-3 series of machines, which was further extended into the DMX-4’s and now the Symmetrix V-Max Systems. With power outages or major power fluctuations or other critical environmental conditions (temperature, water, fire and environmental hazards) in data centers, the vaulting technology saves all the data during the shutdown of the machine offering additional safety features with the customer’s data in transit (channels, cache – memory, etc).
