The Version 02 SIOC (UCSC-S3260-SIOC) uses an integrated Cisco UCS VIC 1300 Series chip
on-board, so there is no removable adapter card. The only replaceable component is an RTC battery.
The Version 03 SIOC (UCS-S3260-PCISIOC) uses a removable PCIe-style adapter card
(half-height, half-length, Gen-3, x8 lane). It also supports up to two 2.5-inch NVMe SSDs and an
RTC battery.
The Version 03 SIOC is supported only with S3260 M5 server node. It is not supported with
earlier server nodes.
