I would like to monitor the RAID array from the VMs, but I'm now paranoid of enabling passthrough as the ESXi VMs were offline for almost a week. I would really like to know if anyone has experienced issues after enabling H330 (or others) passthrough in ESXi 6.5. For 4-5 VMs and a small OS (hypervisor)? You don't need much.:) But then again, you didn't mention what those VMs will run (Exchg, SQL.something with high I/O) or if they're just basic, standard servers or workstations (2K3, web, file, app servers). Agree with Jake though.place the ESXi hypervisor on a flash drive (see: ). Since there is no resource necessity to run the hypervisor on hard disks, going this method (installing/running ESXi on flash drive) frees up 1-2 disks for your storage. Now.for your datastore, I was going to suggest either a RAID5 or RAID10, but if your VMs are not high I/O VMs, I actually suggest 2 RAID5s. My reasoning is solely based on the basic redundancy suggestion to 'not have all your eggs (VMs) in 1 basket':) So, with 2 RAID5 datastores, you can separate/balance out your VMs across multiple datastores instead of just 1. Even in a small org, you want to have good redundancy/failover when able. My.02ยข worth:) Regards, ~coolsport00. Installation is very simple and takes a few minutes. Even child can install it.

You also have the option to create several logical disks using the same spindles, so one array with all 6 disks in it can have a RAID 10 logical disk and a RAID 5 logical disk on it and you can tweak things like stripe size per logical disk. Of course if you're hammering the RAID 10 the RAID 5 will slow down as sharing same spindles. May be best to leave some space so you can extend a logical disk later. I really depends on the amount of IO required to HDD. Certanly you can do it just put everything in a RAID 5 configuration or any other configuration but I would rather split HDD access in some way to avoid contention. Do not put together 2, 3 or 4 heavily used VM in the same disk spin as you will notice a performance degradation. I would rather get a combination of RAID 1 and RAID 5 and spread VM as needed, let say a Heavy used VMs with system not used that frequently or those that does not really need quick HDD access. If you are going to use 4 to 5 VM and six HDDs, just do three RAID 1. If the server and budget allows try get 2x 72 HDD for the Hypervisor itself.
