❓ Frequently Asked Questions (FAQ)
Q: Is this IBM 10N7255 HBA adapter compatible with my IBM Power7 or Power8 server?
A: Yes, the IBM 10N7255 card (Feature Code 5276/5774) is officially supported on IBM Power6, Power7, and Power8 platforms. Just make sure your server has an available PCIe x4, x8, or x16 low-profile slot.
Q: Which operating systems are compatible with this 4Gb Fibre Channel adapter?
A: The IBM 10N7255 adapter is compatible with AIX 5L v5.3 (TL 5300-06 or later), IBM i 6.1 or later, Red Hat Enterprise Linux (RHEL 4 U5, RHEL 5), SUSE Linux Enterprise Server (SLES 9 SP4 and SLES 10 SP1). Please consult IBM documentation for the latest driver compatibility updates.
Q: What is the maximum range of this HBA card with a fiber optic cable?
A: Using shortwave optics (SWO) with 50/125 µm cable, the range reaches up to 500 m at 1 Gbps, 300 m at 2 Gbps, and 150 m at 4 Gbps. With IBM Fibre Channel switches supporting longwave optics, the distance can reach up to 10 kilometers regardless of the speed (1, 2, or 4 Gbps).
Q: Can the 10N7255 PCI Express card operate in a PCIe x16 slot?
A: Yes, the IBM 10N7255 PCIe x4 adapter is backward compatible and works in PCIe x4, x8, and x16 slots. The link speed will auto-negotiate. However, check the PCI card placement rules specific to your IBM machine.
Q: How to verify that the IBM 10N7255 card is working properly after installation on an AIX server?
A: On AIX, use the command lscfg -vl fcs* to list detected Fibre Channel adapters, and fcstat fcs0 for port statistics. The integrated diagnostic tool diag also allows testing optical connectivity thanks to the card's built-in diagnostic capabilities.
Q: Is the dual-port SAN HBA 10N7255 compatible with Fibre Channel switches from brands other than IBM (Brocade, Cisco MDS)?
A: Yes, the IBM 10N7255 supports all standard Fibre Channel topologies (point-to-point, arbitrated loop, fabric) and classes 2 and 3. It is therefore interoperable with most SAN switches on the market including Brocade and Cisco MDS, provided you check your switch's compatibility matrix.
