TrueNAS Core In part 1 I cover some basic ZFS theory and the layout of a high performance ZFS pool for ESXi VM block storage. I will be using TrueNAS Core, which in my opinion is hands down the best free storage platform on the market and it is open source. TrueNAS Core will give …
Introduction to Fibre Channel (FC) If you are new to Fibre Channel SAN technology you should take the time to familiarise yourself with the basic terminology. Fibre Channel (FC) was developed in the late 1980s and became an American National Standards Institute (ANSI) standard in 1994 with it’s physical topology as well as logical topology …
In this blog we will learn how to change the Round Robin Path Selection Policy (VMW_PSP_RR) on FC and iSCSI LUNs in a VMware environment to better balance the I/O load across all active storage paths and make the setting persistent. Modifying the IOPS limitation to 1 will improve performance where an active storage path …
The Scope I’m going to setup Fibre Channel storage network to connect ESXi 7 hosts to a TrueNAS Core storage server using a Cisco MDS series switch. I’ve chosen to use Fibre Channel for my VM datastores because of it’s great performance and reliability and the fact that it works so well with VMware ESXi. Fibre …
I’ve been running the VMs in my home lab on a ZFS pool on FreeNAS and now TruneNAS CORE made up of 600GB 10K SAS drives in a 6 x 2 way mirror configuration for some time and it works fine, but I’ve always wanted to have an all SSD high performance array. The price …
Eventually you will come to the point where you’ll need more storage. I’m running TrueNAS and there are 3 main ways of increasing storage capacity. You could replace every disc in the pool to a larger size, one disc at a time resilvering each disc as you go and once all discs are replaced the …
