Nexus devices run NX-OS, not Cisco iOS, as is typically seen on other Cisco products such as the Catalyst switch range. As such the upgrade process is a little different for this operating system.

In this post I’ll be showing how I sourced the firmware for my device and the steps required to update it to the latest NX-OS version as of September 2018.

Intel Optane 900P SSD – My HomeLab Review

The recently launched Optane 900P solid state drive is Intel’s first consumer storage product to depart from the use of conventional NAND flash and instead utilise Intel’s much newer 3D XPoint technology.

3D XPoint promises higher random I/O performance (up to 550K read IOPS), lower latencies and far better endurance.

In this post I’ll be installing an Intel Optane 900P SSD in my HomeLab and taking a look at its real world performance within a VMware ESXi environment. Most importantly, we’ll see how the added performance translates into real-world improvements with Windows virtual machines.
