Most data centers today have multiple primary storage systems. Often, each one supports a specific platform or environment and each of these systems are either backed up or archived. The problem is most data centers’ cloud architectures are at least as fragmented as their on-premises storage architectures. In this ChalkTalk Video, Storage Switzerland and ClearSky Data discuss how to bring sanity to your cloud strategy.
On-Premises Fragmentation Started It
The problem with multiple primary storage systems is each of these are backed up to one or multiple backup or data protection storage systems, like a disk backup appliance. Some application data needs higher availability than what backup can provide, so they are replicated to a higher performing storage system. And some organizations have an archive storage system to store and preserve old data. Most surveys indicate the average data center has six to ten storage systems. This fragmentation is working its way to the cloud.
How did Cloud Fragmentation Start?
Since the cloud is, essentially, a clean slate, how do organizations end up with a fragmented architecture so quickly? Look at the path the most organizations take to the cloud. They start with backup, then maybe archive old data, they may be attracted to Disaster Recovery as a Service and they may even add some in-cloud compute for analytics. Each of these processes are separate solutions and in some cases a different cloud provider.
The heart of the problem is primary storage. Since most data centers can’t afford all-flash, and in many cases don’t want all-flash, they end up with multiple hard disk-based solutions. Even the flash faithful often end up with two or three all-flash arrays, one for high transactions, one for high density storage and one for average workloads. Multiple primary storage systems has a ripple effect creating the need for multiple secondary storage systems and multiple cloud solutions.
If the organization could develop a cloud-first strategy for primary storage that could solve the cloud fragmentation problem and also provide services like disaster recovery, data protection, copy data management, cloud bursting and data archive.
Of course using the cloud for primary storage has one big problem, the latency induced when accessing data. In the video we address this specific issue and explain how, with it resolved, everything else just falls into place.
In our upcoming webinar “How to Cut Disaster Recovery Expenses – Improve Recovery Times” you’ll learn that one of the best places to start with a primary cloud storage strategy is to use it to moving beyond simple DRaaS to reduce the expense of disaster recovery, while at the same time increasing recovery speeds.
