Buying guide
Picking the right riser
Position
Servers name risers by position, such as primary, secondary and tertiary, or riser 1, 2 and 3, or left and right. Each position has its own part number.
Slot layout
Risers for one position come in different layouts, such as x16/x16 or x8/x16/x8, trading the number of slots against lanes per slot.
Second processor
In two-socket servers, secondary and tertiary risers are usually wired to the second processor and only work when it's installed.
Card height
Riser kits are sold for low-profile or full-height cards, and a full-height card needs the full-height riser and cage.

Frequently asked questions
Do I need a riser to add a PCIe card to a rack server?
Yes. 1U and 2U servers mount cards horizontally on risers, so the riser decides how many cards fit, how long and tall they can be, and how many lanes each gets.
What is a BOSS card?
Dell's Boot Optimized Storage Solution: a card that holds two M.2 SATA SSDs in a hardware RAID 1 mirror for the operating system, leaving the front bays free for data drives.
Can I use a riser from a different server generation?
Generally not. Even within one model line, such as the DL380 Gen9 and Gen10, riser connectors and cages change between generations.
