By not having to worry about it, I would estimate we save two to four hours a week, depending on what's happening, such as if we need to spin up a new server, which would contribute to more time if done the old way.

This forces you to go up to a larger server to get the desired processor, which increases the cost.

Reliable product with efficient automation capabilities

Cisco UCS B-Series manages various processes, including handling payments for over 650,000 growers, running group financials, managing human resources, and operating our main ERP system, SAP. The servers' resilience was particularly impactful. Even during power outages, the servers resumed operations from the last saved point without human intervention. The enhanced processing speed also allowed us to complete tasks that took two days in just one hour. The automation capabilities enhanced efficiency and facilitated integration with our networking components, particularly since we also used Cisco switches. The servers' security was reliable, and formal training on Cisco products made management easier. I rate the product an eight.

Handles workloads and diverse applications efficiently

We have a lot of VMs on Dell PowerEdge Rack Servers. On a single server, we have probably hosted 14 or 15 VMs. Out of these, 8 to 10 are continuously running, and four of them are backup VMs, so it can handle a good workload. For cybersecurity, it is only accessible on the intranet; it is not accessible through the web. We use it for local development purposes, and it is behind our firewall. Its security is strong. We handle a lot of test data for government and confidential customers. It is safe and strong locally. We have not experienced any security issues. Dell PowerEdge Rack Servers have helped to reduce unplanned production downtime if we need to replace a hard disk, instead of completely shutting a server, there is a hot swap feature. It is quite good in that aspect. Usually, for any activity, there is a downtime of about 30 minutes. It has saved a lot of time. We have tried AI workloads for a development environment for a government customer in Singapore. The servers are hosted in Singapore. It is an ML-based engine with AI. It is a government project where data is processed, and we run it on Dell PowerEdge Rack Servers. The benefit of running AI workloads on PowerEdge Servers is that it is easy to allocate memory. The application we are running is memory intensive. It is pretty easy to scale memory and storage.
