Featured Reviews

John Kevin - PeerSpot reviewer
Deputy IT Manager at MBBank
Enforces standardized setup procedures following Certified Validated Design (CVD) guidelines and offers greater flexibility and control over the system compared to traditional systems
The GUI setup follows the right setup, meaning we have to follow the CVDi.e. Certified Validated Design. Everything is clear, because you can build CI yourself, but without rules, it can be messy. With FlexPod, there are rules to follow, making it more standardized. This helps with troubleshooting and compatibility assessments, simplifying troubleshooting significantly. We also use FlexPod pre-validated architectures to validate the design. It is very, very important to us because we had a bad case in 2015 where separate items integrated poorly due to no version or firmware compatibility certification. Troubleshooting became a nightmare. So, standards are crucial for us, and everything entering production should be verified or at least documented for certification.

Open-source nature enables seamless cloud management and customer transition

Quotes from Members

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

Pros

"With the components that come in FlexPod, it has enabled us to reduce connectivity down to one wire, whereas before, we had eight, 12, or 20 wires going to one server."
"It runs very well lights out. Set it and forget it."
"It can scale, compute, and storage independently by what we need."
"There are very many features, but from experience, the single point of contact for support has been valuable to our customers."
"The data is available, compressed, and deduped."
"For the management side of our UCS, it is a single pane of glass for multiple people, whether it is data center, sysadmin, or server deployment."
"We have significantly less latency now with our imagery."
"Our performance increase has been about 15 percent from what we previously used."
"The initial setup isn't too difficult."
"The most valuable feature is the customization. With the customization you can really give the customers what they want."
"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."
"Administrators are very comfortable with the functionality and services OpenStack offers."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"The solution is stable."
"It created a reusable library with OpenStack features."
"The documentation was plentiful and very helpful.​"
 

Cons

"I want to use the expansion to its fullest extent, scaling by deploying 10 to 15 virtual missions in a given FlexPod."
"The solution has not reduced our data center costs."
"Our environment does not always require this solution, so we are not reaping the optimal ROI."
"The interface is a little convoluted."
"Sometimes, it can take awhile for support cases to get to the right people, especially if it's not a P1 case."
"I would like them to scale more to rack unit servers instead of blade servers."
"On the UCS side, sometimes it is difficult to set up."
"There have been issues upgrading the firmware."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"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 deployment process could be easy."
"The pricing of Rackspace is quite high in the Vietnam market."
"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 line migration is a problem."
 

Pricing and Cost Advice

"We have reduced our manpower with the solution."
"We immediately saw a return on investment due to the fact that replacing our legacy storage arrays with the new AFFs reduced the footprint and maintenance costs. Overall, we saw an almost immediate ROI."
"We have saved time and money for new service deployments. Without FlexPod, it probably takes about ten hours. With FlexPod, within two hours, we are up and running. So, we have seen about an 80 percent time decrease."
"Our licensing costs are about $50,000 per year."
"Storage is very expensive. To buy MIC cards and additional storage either on-prem or in the cloud, the IT department does not have money for it, so you need a more niche product or a more flexible way to store your data. That is the benefit that you get from this product."
"If your company really needs to be up 100% of the time, and you need to do a private data center, I don't know if I could realistically actually recommend another blueprint."
"We have saved time and money for new service deployments."
"Everything is purchased, so we do not do any leasing with this product."
"The pricing is low."
"I use it as an open-source tool."

Nutanix vs. VMware EVO:RAIL vs. FlexPod
Originally posted at www.storagegaga.com/dont-get-too-drunk-on-hyper-converged/ I hate the fact that I am bursting the big bubble brewing about Hyper Convergence (HC). I urge all to look past the hot air and hype frenzy that are going on, because in the end, the HC platforms have to be aligned…
