All-flash data center still an idea in development
The concept of the all-flash data center isn't new, and as the cost of SSDs continue to decline, vendors are pushing the of the all-flash data center like never before. Reality is a different matter, though. When it comes to older data, slower technology tiers -- such as tape and high-capacity HDDs -- and the cloud can still save plenty of money and resources. So how much flash is enough? It depends.
IT resources must remain continuously available nowadays. Establishing data center resiliency through technologies like replication and erasure coding, as well as implementing continuous backup and instant recovery, is only a start. Learn how to develop a resiliency plan of your own.
An increasing array of backup, disaster recovery and archiving services has turned the public cloud into a favorite target for secondary and tertiary data. Advances have also made the cloud a viable option as a primary storage tier in the storage hierarchy. Particularly if tier-two or tier-one workloads could benefit from the scalability, resilience and broad accessibility the public cloud delivers. Here's why.
