Genuine Part and Model
Pros & Cons
👍 Pros
- Genuine OEM HP part (model 484822-001) ensures firmware compatibility and preserves HPE support eligibility for MSA2012sa arrays.
- Direct drop-in replacement for failed MSA2012sa controllers minimizes array downtime compared to sourcing third-party alternatives.
- Manages the full 3Gb/s SAS fabric of the MSA2012sa enclosure, restoring complete storage path redundancy when replacing a failed unit.
- Sourcing a genuine part eliminates the firmware mismatch risk that third-party SAS controllers can introduce in HP MSA enclosures.
👎 Cons
- The MSA2012sa is a SAS 3Gb/s platform — this controller cannot be upgraded to deliver 6Gb/s or 12Gb/s throughput regardless of host HBA capabilities.
- Sparse product documentation in the listing means buyers must cross-reference HPE support resources to confirm exact array compatibility before purchasing.
- Installation requires experienced technicians with knowledge of HP MSA shutdown and cache flush procedures — not suitable for self-installation by general IT staff.
- As a legacy component for an older HP storage platform, long-term parts availability will continue to decline as MSA2012sa arrays age out of service.
Frequently Asked Questions
Which HP storage systems is the 484822-001 controller compatible with?
This controller is designed specifically for the HP MSA2012sa storage array. It manages the SAS fabric connecting the MSA2012sa enclosure to host servers. Using it in non-MSA2012sa enclosures is not supported and may not function.
What SAS generation and throughput does this controller support?
The MSA2012sa is a SAS 3Gb/s platform. This controller manages that 3Gb/s SAS fabric — it is not a 6Gb/s or 12Gb/s controller, which is an important consideration if you are evaluating throughput ceilings for the storage array.
Can this controller be installed without professional assistance?
HP recommends installation by experienced technicians. MSA2012sa controller replacement involves proper shutdown sequencing, firmware version matching, and cache handling — incorrect installation can result in data loss or array degradation.
Is this a genuine HP part or a third-party compatible replacement?
The listing states this is a genuine HP part with model number 484822-001. Genuine HP parts are preferred for MSA2012sa arrays because firmware compatibility and HPE support coverage depend on OEM components.
Will this controller require a firmware update after installation?
Likely yes. HP periodically releases MSA2012sa firmware updates, and a replacement controller should be brought to the same firmware revision as the existing array configuration. Check HPE's support portal for the applicable firmware bundle for your MSA2012sa.
