Infrastructure Head at a program development consultancy with 11-50 employees

A very high IOPS that gives more I/O transactions per second

Scalability used to be an issue so at that time it was rated an eight out of ten. We have become OPEX-based and rent storage from them. Physical storage is about 200% of our requirements but we only pay for what we use. This resolved all of our scalability issues. When we reach a certain threshold like 100%, OPEX calls us and asks if we want to add more storage. Our total capacity right now is 300 terabytes but we are only using around 200 terabytes. We bought the storage two years ago and our projections are on par. We don't need more capacity now but have plans to increase in another two years. With our OPEX storage, scalability is rated a nine out of ten.

Cons

"The solution should improve deduplication to get a lot of savings."

"Raw data mapping for storage should be a given option."

"It could use more examples in different languages (API use cases)."

"The pricing of Rackspace is quite high in the Vietnam market."

"In terms of what needs to be improved, I would say the support. Rackspace might have some good support but the open source OpenStack doesn't have support because there are too many versions coming and too many people are customizing it."

"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."

"So for the main stability, there have been a couple of issues that I've experienced."

"OpenStack is difficult for the novice in terms of beginning to use cloud tools."

"The pricing of Rackspace is quite high in the Vietnam market."

"VMware has a side-to-side replication feature, which is still more mature than Rackspace OpenStack's which can't be used in a production environment."
