Exam FlashArray-Implementation-Specialist Topic 2 Question 189 Discussion

The Fibre Channel (FC) I/O card type is the only option listed that is universally compatible and supported across all FlashArray models, from the entry-level //X10 and //X20 up to the high-end //X90 and //XL.
Fibre Channel: Pure Storage architectures rely heavily on Fibre Channel as the primary enterprise storage protocol. All chassis generations and controller sizes feature PCIe risers compatible with Pure's standard 16Gb or 32Gb Fibre Channel HBAs.
Ethernet/iSCSI: While all arrays support iSCSI, the physical card type varies.
10GBase-T: This refers to "copper" Ethernet (RJ45). This card type is not supported on all models. High-end FlashArrays (like the //X70, //X90, and //XL) typically utilize SFP+ or QSFP28 cages for optical connectivity (10/25GbE or 40/100GbE) and do not standardly support 10GBase-T copper cards due to power and latency characteristics.
Therefore, while the protocol (iSCSI) is supported everywhere, the specific physical card (10GBase-T) is not. Fibre Channel cards remain the consistent hardware constant across the entire product line.
