Overview & identity
1000:00ac resolves to SAS3416 and appears separately from SAS3008/SAS3516 entries. A host controller with this ID is not itself an NVMe SSD or a SAS disk.
- Curated identifiers
pci 1000:00ac
A numeric match establishes a candidate family within the reviewed evidence. Marketing names, board variants, subsystem conditions and successful operation remain separate questions.
Driver & binding
mpt3sas contains the exact ID and generation-specific handling. Installed controller firmware and physical cabling decide what storage topology is exposed; the source table is only a candidate-driver record.

Firmware
Device/revision dependent
Controller firmware, option ROM and drive firmware can be separate. The reviewed sources do not establish a host-loaded filename for this profile; firmware revision and update policy require the actual controller and OEM identity.
Read-only diagnostics
Run one displayed command at a time. Replace uppercase placeholders with the affected device, interface or module from your own output. Commands are never executed here. Read-only output can still contain private identifiers.
Check the PCI function and bound driver
lspci -nnk -s BDFReplace BDF with the domain:bus:device.function address. Look for [1000:00ac] and Kernel driver in use. mpt3sas in Kernel modules is only a candidate, not proof of binding.
Inspect visible block-device identities
lsblk -d -o NAME,MODEL,TRAN,HCTLMODEL describes a block device or a controller-presented logical volume; it is not a PCI-controller identity. HCTL helps distinguish SCSI targets. TRAN can be absent, and this list does not establish the complete physical disk topology.
Read controller and transport messages
sudo journalctl -k -b --no-pagerElevated access may be needed. Root reads the current boot kernel journal. Associate mpt3sas messages, port/host identifiers and timeout/reset timestamps with the actual controller. A reset message alone does not prove a bad disk or a firmware defect.
Limitations & related issues
Interface generation does not establish the speed of every target or the layout of RAID volumes. A controller-wide reset can affect several disks without proving simultaneous independent disk failures.
