The ScaleIO UI: EMC has been working with storage for a long time. Therefore, they know how to clearly present any important data, including data flow and each drive's IOPS/bandwidth; and allow the user to easily monitor bottlenecks and problems, especially the rebuild and rebalance status of child objects. It controls them, as well as maintaining them well.
Improvements to My Organization
I just worry about capacity; performance is never a problem.
Room for Improvement
If they could introduce a write cache feature, the product would be perfect overall.
Use of Solution
I have used it for 1.5 years.
We did not encounter any deployment issues; it was very easy.
We have not encountered any stability issues. Meta Data Manager (MDM) is a lightweight process in version 2.0 . The design of MDM totally considers the chance for data loss because the MDM group can be extended to 10 roles to protect the meta data.
Actually, ScaleIO has a limitation of 1000 nodes. We only built up 20 nodes as SDS; that's enough for us.
Customer Service and Technical Support
There are rich reviews, articles and people who are expert and full of passion to solve your problems in their forum.
We previously used vSAN.
We switched because ScaleIO is a pioneer in all-flash; therefore, I applied that in our lab.
First, you should know the concept of data flow in your product so that setup is not a big deal. Then, you should understand the structure of ScaleIO; that is useful for installation.
We implemented by ourselves.
Other Solutions Considered
Before choosing this product, we did not evaluate other options.
Maybe they could support more data types. That way, it would be like setting a gateway to convert any data you want (file or object).
