Best Ethernet Cables for ESXi Hosts

Ethernet Cables For EsxiStruggling to keep your servers up and running?

You’re not alone.

A lot of businesses struggle with server crashes, especially during the busiest times of the day.

But don’t worry – we have the solution for you.

You’re about to find out about the best ethernet cables specifically designed for ESXi hosts.

Introduction to Ethernet Cables

Network cables are the unsung hero of network communication.

They’re the little things that make sure your data is transferred and received in its entirety, with no interference or disruption.

Ethernet cables have been around for years, and ESXi hosts have specific needs that may require a different type of cable.

Let’s explore what you need to know about the best ethernet network cables for ESXi hosts.

Years ago, I experience the problem with servers crashing during the busiest time of the day.

Guess what was causing it? After literally days of troubleshooting, the network team figured it out.

Basically, during the peak hours, our ESXi host network was maxing out the bandwidth of the cheap copper CAT6 cables we were using.

On the Cisco switches, the network team found 1000s of CRC errors on the ports.

These errors were crashing our servers because we were using iSCSI for our storage.

BTW, we were having similar problems with databases also using iSCSI storage.

Best Ethernet Cables for ESXi Hosts

In general, you’ll want to choose an Ethernet cable made of quality materials and designed for high-speed data transfer.

Cat6a or Cat7 cables are typically good for ESXi hosts on a 10G network.

These cables are made of thicker copper wire than standard Cat5 or Cat6 cables, which helps to reduce interference and crosstalk.

They also have a higher bandwidth capacity, which is important for data-intensive applications.

VMware ESXi Network Cable Best Practices

When choosing an Ethernet cable for your ESXi host, it’s also important to consider best practices for cable length.

The maximum length for a Cat6a cable is 100 meters (328 feet), while the maximum length for a Cat7 cable is 150 meters (492 feet).

If you need a longer cable, you can use multiple cables to create a daisy chain.

And don’t forget to be sure to use RJ45 couplers/jacks that are also rated for the high speed and bandwidth of your network.

Once you’ve chosen the right Ethernet cables and jack, your ESXi host network should be able to handle the load.

Here are the best practices you should consider:

  • The type of cable (Cat6e or Cat7)
  • The length of the cable
  • The maximum bandwidth capacity
