Product Overview
The Oracle DE3-24C I/O Module V2 (part numbers 8212680 / 8212681) is the 12Gbps SAS-3 shelf controller used by Oracle DE3-24C and DE3-24P disk shelves. 8212680 and 8212681 are a matched pair of ASSY load numbers for the IOM0 / IOM1 left and right slots — the hardware is identical and the two units are interchangeable.
Key Specifications
| Model | Oracle I/O Module V2 (12G SAS-3 shelf controller) |
|---|---|
| Part numbers | 8212680 / 8212681 (ASSY pair, IOM0 / IOM1) |
| Speed | 12Gbps SAS-3 (SFF-8644 Mini HD SAS) |
| External ports | 4× SAS-3 ports per IOM (Port0/1/2/3) |
| Cabling practice | Port1 / Port2 in normal use; Port0 / Port3 reserved for cascading further shelves |
| Role | SAS expander for 24 drives, SAS routing, shelf monitoring and alerts to the ZFS BUI |
| Redundancy | Dual-IOM, dual-path; a single IOM failure does not interrupt service |
| Serviceability | Hot-swap CRU, replaceable without downtime |
Compatibility
- Disk shelves: DE3-24C (4U, 24× 3.5" LFF SAS-3), DE3-24P (2U, 24× 2.5" SFF SAS-3).
- Storage heads: Oracle ZFS Storage ZS3-4, ZS4-4, ZS5-2, ZS5-4; ODA database appliance back-end expansion shelves.
- Important: DE2-24C / DE2-24P use 6G SAS-2 IOMs and are not interchangeable. V1 and V2 firmwares differ — always run IOMs as a same-firmware pair.
Hardware & Monitoring
- LED indicators: OK (green), Fault (amber), Link/Activity port blink.
- IOM temperature, voltage, SAS link state, drive presence and fault reporting are visible in the ZFS BUI / ILOM.
- IOM power draw is minimal; shelf power is supplied by the 580W PSU modules (7354096).
Availability & Support
Pulled units in tested condition, Shenzhen stock, 3 months to 3 years warranty depending on batch. We verify firmware version pairing before shipment and support on-site replacement in Shenzhen within 4 hours, next business day across Guangdong province.
Frequently Asked Questions
Are 8212680 and 8212681 two different products?
No. They are the ASSY load numbers for the left (IOM0) and right (IOM1) slots of the same I/O Module V2 hardware; either part works in either slot and they can be mixed.
Can I mix an IOM V2 with an older V1 module in one shelf?
Not recommended. V1 and V2 carry different firmware baselines; Oracle expects IOMs to run as a same-version pair. We match firmware versions before shipping a replacement pair.
Will this controller fit my DE2-24C shelf?
No. DE2-24C / DE2-24P shelves use 6G SAS-2 I/O modules with a different hardware generation. Send us your shelf model and we will quote the correct part.
