Is it possible to configure a Dell T710 with a PERC H200 RAID controller and 8x 15k 2.5" HDDs and then add 4x X25-E SSDs, purchased separately, when the system is setup, and not sacrifice performance by mixing the SSDs and HDDs?
Or is it better to buy an LSI #9260-4i RAID controller just for the SSDs? In this case, the SSDs would not be able to be connected to the backplane and not hot-pluggable, but would be cabled to the 9260-4i.
The configuration will be System Drive: 4x X25-E in RAID 10 (C:) volume DataDrive1: 4x HDDs in RAID 10 (D:) volume DataDrive2: 4x HDDs in RAID 10 (E:) volume
The Dell documentation says that when SAS and SATA (SSD) are mixed, only two SAS drives can use used and they must be in slots 0 and 1. Yet, the Dell configuration web page does not give an error message when you select 2 SSDs and 8 SAS HDDs.
