We approached this in a phased manner, connecting 2 x old FC switches to the existing 8Gbps ports on the compellent (Fault Domain A and Fault Domain B), then connected the new 16Gbps interfaces to new FC switches on new Fault Domain C and new Fault Domain D. We are…
This is a simple script which takes a CSV input file (plus a few arguments) and updates the zoning config. The script * Checks that the config name already exists * Checks that the specified storage alias already exists * automatically saves the config * automatically enables the config --> note - this…
A common question when provisioning storage is "which presentation protocol do I use". This article isn't really designed to deep-dive into each protocol, but rather provide an architectural overview of each delivery method to assist with designing a new storage implementation. NAS vs SAN This is…
This is just a simple cheat sheet I'll likely expand over time to capture all the useful information pertaining to fibre optic communications. Connectors The most common data connectors are outlined below LC Lucent Connector Typically used for 4Gbps+ Fibre Channel and 10Gbps Ethernet communications. Most structured cabling…
I came across a situation that ordinarily should have been "impossible" (with standard physical HBAs), but as NetApp uses software coded HBA WWPNs, I was faced with duplicate WWPNs on a C-DOT HA pair of nodes. First, it is necessary to understand how Data ONTAP generates WWPNs for…
