Hello, this is my first post.
Is it possible to add a new controller in sas / sata emulation?
SCSI Emulation is vendor: 1000 ("LSI Logic / Symbios Logic"), device: 0030 ("53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI")
SAS Emulation is vendor: 1000 ("LSI Logic / Symbios Logic"), device: 0054 ("SAS1068 PCI-X Fusion-MPT SAS")
SATA Emulation is vendor: 8086 ("Intel"), device: 2829 ("82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller")

Someone is developing a new controller emulation?

Thank you

What is wrong with the existing controllers? Is it allowed to emulate/virtualize the hardware you mention?
