It is stable. It is much more stable than other hardware, like Dell and HP. 

During the upgrade earlier, it was recommended to upgrade from south to northbound, upgrade Viccars, then blade, then IO, then SaaS, then click interconnects, Site A, and then come to Site B.

Now, we have an opportunity to automate the upgrade activity. 

However, during our upgrades, when we did the entire infrastructure for FIA and FIB, during the reboot, FI failed very frequently. 

FIA or FIB failed in approximately six to seven situations out of ten upgrades. The replacement of FI took much more time than if we had a business hour for four hours; it took approximately one or two days. Running the entire infrastructure on FIB or a single FI is really risky. That is a main area of improvement for Cisco UCS.

It is stable and one of the most reliable systems I've ever encountered. You won't regret going for Cisco UCS B-Series because it is very good.

These are not stable servers because we have seen some cases where the servers have gone down when there were power fluctuations. Though the servers came with in-built batteries and in-built SPS, the blade servers were not accessible. They're designed to have one blade not dependent on another blade, but they still went down.

It is a stable solution, considering that I haven't seen many challenges in the tool. Cisco has a good record from the support perspective, making it an area where I don't see any specific challenges.

We haven’t faced any issues with the solution’s stability so far.

I rate the solution ten out of ten for stability.

The solution is stable.

It is a stable platform.

It's pretty stable. I'd rate the reliability eight out of ten. 

The solution is stable.

It's very stable.

It is a very stable solution, like a rock.

Stability-wise, it is excellent.

The tool is stable. I rate the stability a nine or ten out of ten.

Cisco UCS B-Series is stable.

There was only one server failure during my use of 24 blades in my old system. There were 20 blades in my new/replacement implementation. In reality, this is a small installation.

This is a stable product. However, if the customer is using devices from different vendors on the same network then there can be some small problems.

It is a stable solution.

We went through the original teething pains of any new system. In particular, once we had our operational epiphany on what the potential was, we were limited by how fast features could be added to UCS Manger. With XML extensions, UCS Central (Manager of Managers) and UCS Director (Automation), we have enough on our plate.

I rate the solution ten out of ten for stability.

We hit a software defect once that caused a reload of some critical assets. This was immediately resolved and is the only true case of a stability issues I have seen.

The solution is stable. 

We have found this to be a very stable solution.

The B-series is definitely stable, that is for sure. We rarely have any issues with the B-series. If there are any issues, we are covered by the four-hour response window and we can get parts replaced within a few hours if there's any faulty hardware. Stability is something I would say is over 90 percent better than most other products.  

The solution's stability is good. Although, it is much more complicated regarding usage or management compared to other vendors.

The stability of the Cisco UCS B-Series has been good. We have not had a problem.

Although we have experienced some hardware issues, that is normal for this product. Overall, it is stable.

This solution is very much stable, especially the network side.

No issues with stability that we have not seen across other systems. In particular, due to Cisco networking dominance, the focus is on drivers that work with their products for all the competitors as well. Networking is typically the server area with the most work to be done – but this is the strength of Cisco.

The stability, in general, has been amazing. There are no bugs or glitches. It doesn't crash or freeze. Cisco is extremely reliable and offers good performance. 

Very stable and very reliable.

Over time the solution became more unstable. This is why I planned for a hyper-converged HyperFlex Infrastructure. Hopefully, this will reduce the percentage the server consumes and an overall performance improvement.

This is a very stable product.

No issues encountered.

I would rate the product's stability a seven out of ten since we encountered bugs during the upgrade. 

The stability of the solution is fantastic. It's one of the greatest selling features. It doesn't crash or freeze. There aren't bugs or glitches. It's extremely reliable.

Stability is a non-issue with Cisco UCS. We have not had any stability issues and to just mention, the Cisco UCS team employs strenuous testing mechanisms of all the UCS components. They provide this for all their firmware updates prior to public release. This is not to say that we've not had any issues, but the issues have been extremely small in comparison to the amount of systems we've deployed. Those issues were quickly identified, rectified and the systems were brought back online in a prompt manner with minimal customer business impact.

Some of the version of firmware does have issues but Cisco is very good at fixing the bugs and giving new firmware versions.

No, we haven't had issues post setup.

This solution is stable and powerful - we've had no problems with it.

We haven't had any problem or any outage, and it's always running. Every process and everything you run, memory and cache memory, is always running. It's very stable.

The solution is stable. We haven't encounter any failures or problems in these particular servers. We have had three to four years without any downtime happening.

B-Series blades, along with the C Series tack mounts are the most reliable server hardware platform I have worked with in my 20+ years in the industry.

No, the product has been stable.

The solution, for the most part, is pretty stable. There aren't really bugs or glitches and it doesn't really crash or freeze. It's pretty reliable. 

The stability and performance of this Cisco product are excellent. There are no bugs or glitches. It doesn't crash or freeze. It's very reliable. 

We had some issues with certain NX-OSs in the Fabric Interconnect.

There have been no performance issues.

As with any system, there are very occasional bugs. But Cisco is quick to remedy any issue. Firmware is often already out to fix issues that we run into.

This is a stable product.

This solution is stable, we had not had any issues.

It is very stable.

No.

I've had no issues with stability.

I have not encountered any stability issues.

The product is stable (with new versions of the firmware), although previous versions were having some issue with stability.

Cisco UCS B-Series is a reliable solution.

We've had no issues with stability.
