Cisco NX-OS is a network operating system presented as a solution to help network operations move at the speed of business, with comprehensive automation, extensive visibility, and flexible open architectures for data center networks. NX-OS is the network operating system for all fabric architectures, from traditional L2/L3 to overlay-based fabrics.Cisco NX-OS powers the modern data center.
This easy solution can be a great help for the big companies on easy multiple data processing and effective networking solutions for the various departments and also generating the real-time data reports with Cisco NX-OS is excellent. For the new users, it takes no time to become a pro on full manipulation of the features and offer the best and quality management services.
If you have one user or 1000's of users (especially using Windows), Windows Server is a no-brainer! The only reason I would suggest going with a Linux server is if you have old hardware (Windows Server is more process intensive than Linux). But, Linux is open-source, so anyone can publish updates/security updates, but on the flip side, malicious people also have full access to Linux's codebase allowing for much easier writing of exploitations/viruses/malware/ransomware.
Cisco NX-OS does a great job of supporting high dense environments due to Cisco NX-OS based devices having some of the fastest packet switching performance
Cisco NX-OS supports high bandwidth environments really well due to the high throughput links that are typically found in Cisco NX-OS network appliances
Cisco NX-OS provides some of the best redundancy in the way of "Active-Active redundancy" via it's VPC technology. This is especially desirable in data center environments.
I think one thing we'd like to see a bit more in the Nexus space is probably the troubleshooting features. So one would be the I perf feature and being able to test network traffic across links. Don't get me wrong, there's a lot of really good features in terms of troubleshooting, but one particular one that we like to see is where we can test network traffic. We can make sure that we have good latency, we got good bandwidth utilization as well. For us that's a big one. We've got to use third party tools to do that. So if the NXOS platform can do it, that's one of the thing we've got to do.
DHCP Server could be better - we use the router for DHCP Routing
Print Server - not a fan of using the server as a print server since you have to license it. Direct access to printers via IP addresses is a much more efficient way to go
Better backup program - we utilize a third-party program that gives us more flexibility when restoring individual files.
I've carefully reviewed the servers and services currently running on Windows Server 2012, and given the opportunity would renew them as is going forward. There are two systems I currently have in place, one is a very large Linux implementation for a large ecommerce site, and one is a very large backup solution front ended by FTP servers running Linux. Neither are well suited for Windows, but the overall network infrastructure is and will be Windows Server for the foreseeable future.
NX-OS has many similarities with the traditional IOS which is quite beneficial when it comes to configuration and learning. As a native Linux system, there are a lot of tools and features that can be enabled for any use case.
There are simply too many different parts of Windows Server to make it a cohesive piece of software. While some of the newer features found in Windows Server 2012 and 2016 have nice UIs that are logically laid out, there are enough parts of the system that is still based on old code with clunky UIs and confusing options to make Windows Server a particularly user-friendly experience.
Our switches running NX-OS have provided solid consistent throughput. We haven't had any issues with it not being able to handle what we threw at it. The latency is extremely low. It also has multiple management options that we hope to pursue in the future.
Cisco support never fails me. In terms of timely response, no one is on par with them. They really value the impact of having technical issues and potential business stoppage. Also, their support staff are well equipped with knowledge and skills and easily resolve the most common incidents. Most of the time, we can resolve an issue by just calling them once.
Microsoft's support is hugely wide-ranging from articles online to having to contact them directly for the more serious issues. In recent years when I have contacted them directly, I have found the support o be excellent as I have found myself connected to very knowledgeable people in the field in which I needed the support. The online support available is vast and I tend to find most of the time that there is always someone out there who has had the same issue as me in the past and knows something about how to resolve it! This is the advantage of using industry standard and long-established systems such as Windows Server.
Make sure that you have detailed processes in place for every server instance you plan to install/upgrade, if possible get the base OS loaded and Windows Updates applied ahead of time, and if using a VM take a snapshot prior to installing each role, as well as along the way.
I am much more familiar with the commands in Cisco IOS as it has been around for many more years. I know why NX-OS is a different system and can see the benefits of the fibre channel integration, but I do not understand why the commands had to use a different syntax. With the Nexus switches you don't get a choice of operating system unfortunately.
I didn't use any other system which gives the same functionality and I am not aware of any. The full integration between all components and especially the ability to integrate mail via Exchange or even via a hybrid setup with the Ofice365 cloud, including the ability to directly manage the cloud from the server, using Power Shell, is something I didn't see anywhere else.
Up to now, we haven't had a major ground-shaking attack on our networks but we take no chances by using NX-OS alongside a SIEM. All endpoints and workloads are secure so I would say we have plenty of trust in their security model.
Cisco NX-OS has provided extremely high availability in our organization; especially when we've had to perform upgrades. We've been able to leverage their ISSU technology to perform system upgrades/downgrades with no downtime
Cisco NX-OS has allowed us to leverage high throughput packet forwarding for all of our application needs. I can't remember the last time anyone has complained about slow application speeds in my environment.
Because of our Microsoft Campus Agreement, Windows products are fairly affordable for us and that has been a huge blessing. We are considering some Azure cloud options and some of that is covered under our Campus Agreement, making it a nice incentive to start migrating certain apps and functionality to the cloud
I don't have access to our budgets so I cannot give a good answer as far as the impact of ROI on our institution, but if your company can afford it, you cannot go wrong with Windows server. Not having to send your sys admins to Linux or Unix school alone is a big savings as well as not having to train your staff on using a Linux desktop instead of a Windows-based one.
The compatibility with end users of all varieties and platforms will definitely impact your ROI in a positive way. We have Apple users, Android, Windows, and even a few Linux end users on our campus and Windows server works quite well with all of them.
