PURE storage arrays are one of many new “All Flash” Storage arrays in the marketplace with compression and deduplication built into the product. This means customers can buy 20TB of storage, but actually store 80TB of data because of these space reduction technologies.
Customers love these arrays because they improve the cost effectiveness of all flash storage. PURE Storage environments deliver:
- Excellent sustained performance
- Excellent compression and deduplication services
- Simplistic set up and run
While these arrays are simple to implement and simple to manage at an operational level, there are some unique features of these arrays that can cause management related issues if not properly maintained.
So, what are those unique features and what issues do customers need to be aware of? PURE Storage arrays are “variable capacity arrays” which means the overall capacity of any array can, and often does, change over time.
Raw Storage: 10 TB
Effective Storage: 40 TB
The challenge with this environment is NOT managing to the effective capacity – it is the fact that “Effective Capacity” changes over time. This may not sound so difficult, but when your effective capacity changes by 20% over a 1-2 week period this can create a variety of unexpected and sometimes even “emergency” events.
