Planning implement new Hyper-V server with 4 vm's.
I bought a 4 bay Server which has 3.5" 600GB 15K SAS 12Gb Hot Swap 512n HDD with raid 5.
Also, this has M.2 CV3 128GB SATA 6Gbps Non-Hot Swap SSD.
 
Planning to install Host OS (server 2016) on M2 SATA SSD .
I am going to use the 3.5" 600GB 15K SAS 12Gb Hot Swap 512n HDD with raid 5 for VM's storage.
 
Host server only going to have the hyper-v role.
 
1) I just wanted to find out whether 128GB is sufficient for HOST OS ?(capacity)
 
2) 3.5" 600GB 15K SAS 12Gb Hot Swap 512n HDD with raid 5 is ok to store all my VM's ?(performance vise)
 
2) Performance vise RAM 16GB X4 TruDDR4 2666 MHz (1Rx4 1.2V) RDIMM sufficient to implement Hyper-V hypervisor

it'd depend upd on your Hyper-V server roles...

for normal performance it's fine...

but still there are sum guidelines you may follow please check the following link

as well you can see the performance calc

for an idea..

all the best

Four spindles will yield maybe 250 IOPS per drive. That's not a lot for any kind of virtualization setup.

Go for four SATA SSDs to give a boost to IOPS, probably 10K to 25K per drive, and throughput which can be 250MB/Second and up per drive.

Go for medium duty drives such as the Intel SSD D3-4610 series SATA 2.5".

EDIT: A minimum of 64GB ECC RAM should be set up in the host.

I have two very thorough EE articles on all things Hyper-V:
