Sorry, this should have been in Servers-Workstations, I'm marking this as answered.
Does anyone know if the Ultra 40 M2 will recognize a 1 TB SAS disk, and/or will a 1TB SAS disk work OK in the Ultra 40 M2?
I don't think that SAS disks over 300GB were available when the U40 was an active product. Is there any reason to think that a
1TB SAS disk would not work? The specs say that 750GB SATA disks were supported, as I recall.
