Infrastructure Manager at a financial services firm with 5,001-10,000 employees
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.

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.

Quotes from Members

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

Pros

"This solution has been helpful to our organization in many ways including provisioning storage, provisioning applications, and maintaining applications."
"It’s easy to deploy and easy to scale when you need, as it’s a proven architecture that works with tools for virtualization or a private cloud environment."
"The most valuable features of the solution are reliability, scalability, and support."
"I like the combination of the brands that they decided to include, in terms of its compatibility, e.g., they integrated UCS into this solution."
"It has been very scalable – our guys scale it across six sites right now."
"It just gave us everything in one box."
"Having a proven solution and knowing that it works gives us peace of mind and ease of management."
"We haven't had any downtime in four years."
"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."
 

Cons

"A unified interface for all the components would be a great start."
"There is always room for improvement. I believe we can do hot swaps on the fly. On the release upgrades, if there was a way to do a release on the fly, that would really be cool because it does take some downtime. It takes restarting. It is more of a software thing. Customers hate doing releases."
"Cisco support is much slower. Opening cases with Cisco tech is sometimes a bit tedious. The return time for less important calls can be slower. Even Priority 1 calls can sometimes be a bit long and they will have to call me back."
"The procedure for contacting technical support could be simplified."
"I would like to see programmability into a SaaS-based offering, as I know Cisco's going in a lot of directions with their Intersight application."
"Currently, the only issue we have is with our backup solution."
"We dislike going online with the robot stuff. Many times, it has delayed our reaching out to a real support engineer."
"We have had a few stability issues with some major bugs with it, with ONTAP. We had a particularly nasty bug with one of the QLogic CNA cards, which actually took, probably, seven months to resolve."
"Raw data mapping for storage should be a given option."
"The solution should improve deduplication to get a lot of savings."
 

Pricing and Cost Advice

"Coming from a rack and stack server model to FlexPod, it has saved us a lot of time (approximately hundreds to thousands of hours)."
"It created lower total cost of ownership. Previously, we had disparate storage and servers, and there were bits of kits everywhere. Now, we have two data centers with almost identical setups in both."
"Anytime that you are buying any storage make sure you understand storage. Do not just buy storage based on what somebody sells you in terms of IO or throughput."
"We have saved time and money for new service deployments."
"We have reduced our manpower with the solution."
"Buy storage based on the solutions you need, the technologies you need, and what will make your life a lot easier down the road."
"We definitely saw a lot of operational cost savings using FlexPod. As far as capital outlay goes, that was a little bit too much for us to swallow and we weren't able to recognize enough savings in that area to afford it."
"It is not cheap, but there is a return on investment in time saved and efficiency."
"The solution is enterprise level so it is expensive."

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…
