12345678910
Compared to the previous generation PowerEdge T410, the T420 supports up to 33% more
processor cores, 50% more DIMM slots, 166% more internal hard drive storage capacity, and the
greater I/O bandwidth of PCIe 3.0. Its high quality is backed by high availability features including
redundant SD cards for failsafe hypervisors and soft, fault-tolerant fans, and optional features such
as redundant high-efficiency power supplies and hot-plug hard drives.
The T420 is the new generation PowerEdge server replacing the T410. Table 2 compares some of
the T420 features to the T410 features.
