The HP 9000 D-Class servers were flexible, upgradable and scalable PA-RISC enterprise servers for Unix applications of the late-1990s. They were designed to bring mid-range performance for an entry-level price, with processors from 32-bit PA-7100LC to 64-bit PA-8200 and some multi-processing SMP support.

All D-Class servers were HP 9000 800 server series and used two different architectures: LASI for PA-7100LC and PA-7300LC models and U2/UTurn for PA-7200/PA-8000 models. They were built into a mid-tower case for use as a departmental server. Still rather big and loud machines for the late-1990s.

R-Class Ultralight servers R380 and R390 are rack-mountable versions of their D-Class counterparts D380/D390. They are technically almost identical, except some differences in the I/O and storage configuration.

The D-Class were technically close to the larger K-Class servers.

In the 1990s, D-Class servers were part of the US Navy TAC-4 program, in which HP was a vendor supplying RISC Unix computers for uses throughout the Navy. The D-Class were part of a technology refreshment of TAC-4 in 1996.

Different models were available which could be upgraded within the series to another model with various options for each system. The servers used the following naming convention and were part of the HP 9000 800 series:
