Update : But you may want to only go to 20GB depending on your setup! One of my colleagues discovered 8GB over-provisioning wasn’t even maxing out 10Gb network (remember, every write to VMware is a sync so it hits the ZIL no matter what) with 2 x 10Gb fiber lagged connections between VMware and FreeNAS. You can boot into an Ubuntu LiveCD and use hdparm, instructions are here: You can also do this after after VMware is installed by passing the LSI controller to an Ubuntu VM (FreeNAS doesn’t have hdparm). If you’re going to use an SSD for SLOG you can over-provision them. Optional: Over-provision ZIL / SLOG SSDs. If you can’t P20 in aversion later than P20.00.04.00 then use P19 or P16. Some earlier versions of the P20 firmware were buggy, so make sure it’s version P20.00.04.00 or later.

(If you already have the card passed through to FreeNAS via VT-d (steps 6-8) you can actually flash the card from FreeNAS using the sas2flash utility using the steps below (in this example my card is already in IT mode so I’m just upgrading it): ] # cd /root/ Supermicro firmware: For IBM M1015 / LSI Avago 9220-8i Here’s instructions to flash the firmware: I strongly suggest pulling all drives before flashing. Flash HBA to IT FirmwareĪs of FreeNAS 9.3.1 or greater you should be flashing to IT mode P20 (looks like it’s P21 now but it’s not available by every vendor yet). I’m using DC S3700s because that’s what I have, but this doesn’t need to be fast storage, it’s just to put FreeNAS on. Also get one (preferably two for a mirror) drives that you will plug into the SATA ports (not on the LSI controller) for the local ESXi data store. The LSI2308/M1015 has 8 ports, I like do to two DC S3700s for a striped SLOG device and then do a RAID-Z2 of spinners on the other 6 slots.

Added sections 7.1 (Resource reservations) and 16.1 (zpool layouts) and some other minor updates. Also, I believe Avago LSI P20 firmware bugs have been fixed and have been around long enough to be considered stable so I’ve removed my warning on using P20. This guide was originally written for FreeNAS 9.3, I’ve updated it for FreeNAS 9.10. If you run into any problems and ask for help on the FreeNAS forums, I have no doubt that Cyberjock will respond with “So, you want to lose all your data?” So, with that disclaimer aside let’s get going: I should note that I myself would not run FreeNAS virtualized in a production environments. This post has had over 160,000 visitors, thousands of people have used this setup in their homelabs and small businesses. This is roughly based on Napp-It’s All-In-One design, except that it uses FreeNAS instead of OminOS. This is a guide which will install FreeNAS 9.10 under VMware ESXi and then using ZFS share the storage back to VMware.
