Which processor generation
The M10-1 chassis carried two processor generations under one product name, and the vendor literature does not settle which is which at one point. The original 2013 part is the 16-core SPARC64 X. A later SPARC64 X+ option added on-chip SIMD, decimal floating point, and crypto instructions, offered as a 16-core/3.2 GHz, a 16-core/2.8 GHz, or an 8-core/3.7 GHz part.
The conflict is over the 16-core 2.8 GHz SKU. Fujitsu’s 2015 data sheet
assigns 2.8 GHz to plain SPARC64 X and reserves the X+ label for the
3.2 GHz (16-core) and 3.7 GHz (8-core) parts. Oracle’s 2016 FAQ and its
Oracle-branded data sheet instead describe “the 8-core 3.7 GHz, the
16-core 3.2 GHz or the 16-core 2.8 GHz SPARC64 X+ processor” — folding
the same 2.8 GHz part into the X+ generation. I am not picking a side
here. The machine in the lab is the 16-core 2.8 GHz configuration —
exactly the SKU the two vendors label differently — bought secondhand as
an Oracle-badged M10-1 (the listing’s X1109A is a bundled dual-port 10GbE
SFP+ adapter per Oracle’s PCI-card documentation, not a system part
number). Its own CPU
FRU or part number settles which generation name applies, independent of
the disagreement, and that check is still outstanding. The Processor row
above therefore names both generations rather than committing to one.
Memory population
The 16 DIMM slots are filled in fixed steps, not one at a time: supported install counts are 4, 8, 12, or 16 modules (quarter, half, three-quarter, or full). Registered DIMMs come in 8/16/32 GB and load-reduced DIMMs at 64 GB; a full set of 32 GB R-DIMMs reaches 512 GB and a full set of 64 GB LR-DIMMs reaches 1 TB. The 512 GB / 1 TB ceilings and the 4/8/12/16 rule agree across the Oracle 2020 data sheet and the M10-1 service manual (C120-E681-19EN, §2.2.1). The earlier 2015 Fujitsu sheet predates 64 GB DIMM qualification and states only the 512 GB figure, which is a snapshot in time rather than a conflict.
The unit in the lab is populated with eight 16 GB DIMMs — 128 GB, a half fill of the sixteen slots — and two 600 GB SAS drives, per the eBay listing it came from.
Single-source and unresolved figures
These come from one document each and are recorded as unverified pending a second source:
- Memory bandwidth: 102 GB/s per chip — only the Oracle-branded (smi-tech mirror) data sheet states it.
- External expansion: up to 23 PCIe slots total via external PCI Expansion Units. The 23-slot ceiling appears in several documents, but only the Oracle 2020 data sheet ties it to a specific “three PCI expansion units connected” configuration.
- Power supplies: 2× hot-swap AC, 770 W rated, 1+1 redundant — stated in the Oracle 2020 data sheet, not in the 2015 Fujitsu sheet.
- CPU Activation portability/failover: activation licenses can move between M10-1 units, and an unlicensed core can take over automatically for a failed licensed one — only the Oracle 2016 FAQ states this.
- Last-ship date: February 2018, from a single mirror of an Oracle support document that otherwise sits behind Oracle’s paywalled portal. Carried here with that caveat.
Two figures genuinely conflict between vendor documents and are left unresolved. The 16-core 2.8 GHz generation label (X vs X+), covered above; and maximum power draw for SPARC64 X+, where the 2015 Fujitsu sheet says 805 W and the Oracle 2020 sheet says 849 W (100 V) / 824 W (200 V) — possibly different configuration assumptions between editions, but not reconciled by either. The SPARC64 X (original) figure is 763 W, from the 2015 Fujitsu sheet only.

Per the Fujitsu M10-1 data sheet (2015-04-07), the Oracle-branded M10-1 data sheet (copyright 2020) and FAQ (copyright 2016), and the M10-1 service manual (C120-E681-19EN) for the memory-population rules. All Fujitsu documents were recovered from the Internet Archive; the live and archived links are on the overview page. Rows carrying a single source or an unresolved conflict are called out in the notes above rather than presented as settled.
