PureSystems, something old, something new, something from big blue
PART I For a certain generation of IBM faithful or followers the recently announced PureFlex and PureApplication systems might give a sense of DejaVu perhaps even causing some to wonder if they just woke up from a long Rip Van Winkle type nap. Yet for another generation who may not yet be future…

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

"The strengths of the system is how the Flex scales from a very powerful, next generation BladeCenter all the way up to an IaaS platform."
"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."
"The open-source nature of OpenStack provides significant value."
"OpenStack allowed for mass uploading of images to Akamai cloud services."
"There are many services that can be directly used which are not available in VMware."
"It was a very flexible and scalable solution. It was very useful because we were not dependent on a single vendor's solution. Increasing the number of machines or changing the hardware configuration was very easy."
"The documentation was plentiful and very helpful.​"
"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."
"It created a reusable library with OpenStack features."
 

Cons

"The FSM does not quite deliver in the areas it plays too. A fairly sluggish interface that is more complex and less streamlined than it perhaps could be, holds it back and deployment of certain functionality from the switches requires more user intervention than feels necessary."
"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."
"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."
"We are moving from Rackspace OpenStack to CloudStack due to the requirement of human resources and technicality. There are lots of moving parts in Rackspace OpenStack."
"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."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"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."
"The line migration is a problem."
