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.

Cloud storage and email have supported our association but usability and search still need work
Rackspace OpenStack can be improved because it wasn't clear that you have to cancel 30 days before; otherwise they charge you for the month. I didn't really feel there was anywhere I could go if I had questions in order to live chat or reach out to someone; if that exists, it wasn't made apparent to me. Being able to search keywords and having what you're looking for come up, whether it's an email or in the drive, could definitely be improved, and making it work better with cell phones and improving the setup to be more user-friendly would be helpful.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Replication and DR implementation became faster."
"The solution has high IOPS and the I/O is important because it gives us more transactions per second."
"The combination of Cisco's architecture and IBM's flash technology, where Cisco provides FI technology for one simple architecture and IBM's flash technology is fast, is valuable."
"Customer Service: Top. Technical Support: Top"
"Rackspace OpenStack positively impacts my organization by making processes easier since I do not need to manage all servers manually because it efficiently manages server operations and maintains proper data, which saves time."
"Rackspace OpenStack impacted my organization positively in that the drive helped me keep files in an organized folder, and obviously we needed email addresses to be able to communicate with each other and for outsiders to be able to email us."
"The most valuable feature is the customization, and with the customization you can really give the customers what they want."
"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."
"The documentation was plentiful and very helpful.​"
"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"The open-source nature of OpenStack provides significant value."
 

Cons

"The solution should improve deduplication to get a lot of savings."
"Raw data mapping for storage should be a given option."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"It should have a single dashboard for cloud management and on-premises systems"
"Rackspace OpenStack can be improved because it wasn't clear that you have to cancel 30 days before; otherwise they charge you for the month."
"It could use more examples in different languages (API use cases).​"
"The pricing for Rackspace OpenStack is sometimes not competitive according to other market products, as sometimes the price is high for some components like Advanced Cluster Management (ACM) and Advanced Cluster Security, which are very costly add-ons, not the main license."
"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."
"As a beginner, I find some difficulties in understanding Rackspace OpenStack, as it can be complex without a foundational grasp of cloud and networking concepts."
 

Pricing and Cost Advice

"The solution is enterprise level so it is expensive."
"The pricing is low."
"I use it as an open-source tool."
