HP Smart Array RAID Controller Naming Convention

This question tests your ability to decode the HP/HPE Smart Array controller model number - each segment of the name has a specific technical meaning.

A typical model looks like: P408i-a

The 5-Position Breakdown

Position-by-Position Explanation

1. Class of RAID Controller (P, E, H, B) The leading letter defines the performance/feature tier. P = Performance (enterprise), E = Entry-level, H = HBA-mode capable, B = Basic embedded. This comes first because it defines the product family.

2. Smart Array Series (4, 8, etc.) The first digit indicates the generation/series (e.g., 400-series, 800-series). Higher = newer generation with more features.

3. Number of SAS Lanes (08, 16, etc.) The middle digit(s) indicate lane/port count, which directly maps to how many drives the controller can address natively.

4. Port Type (i, e, ie)

• i = Internal ports only
• e = External ports only
• ie = Both internal and external This determines cabling and enclosure compatibility.

5. Controller Type / Form Factor (a, ar, p)

• a = Standup (standard PCIe slot)
• ar = AROC (modular/mezzanine for blades)
• p = Plug-in card variant This comes last because it describes the physical installation method.

Common Mistakes

• Confusing position 3 and 4 - students swap "lanes" and "port type" since both relate to connectivity. Remember: count comes before direction (how many, then which way).
• Thinking position 1 is the series - the letter is the class tier, not the generation number. The series number follows it.
• Ignoring form factor entirely - on blades vs. rack servers this matters significantly for compatibility; it's not just cosmetic.
