I plan to change the hardware for may SQL Server, and upgrade it to SQL Server 2016 Enterprise. AlwaysOn AG will be built on top of two nodes + dr.
There are two options I have in mind for storage:
have only local disks, ssd's in RAID1, with separate disks for Windows, Data, Logs and TempDb have a hybrid of local storage with ssd's for TempDb (RAID1) and the rest of the disks for Windows, Data and Logs to be provisioned from a SAN over the network I personally prefer the option with everything on local storage, because:
you get rid of single point of failure (the SAN) faster speeds on the local storage, the SAN will not have ssd's no network bottlenecks Are there any major disadvantages of using local storage?
Is using SAN for storage a better option?
Regardless of the solution, the hardware will be rented from a hardware provider. So there will be no buying involved.
Thanks in advance!
