Flexible I/O; Memory Scale-Up Board; Virtual Support Virtualization Technology (Vt) Function; Management Board (Mmb) - Fujitsu PRIMEQUEST 2400E3 General Description Manual

CHAPTER 1 Product Overview
1.4 Hardware technologies
For detail on the target of the DR function and OS supporting DR, see ''Table 3.12 DR Supported list' in 3.2.1
Dynamic Reconfiguration (DR)' in PRIMEQUEST 2000 Series Administration Manual (CA92344-0537)

1.4.16 Flexible I/O

The Flexible I/O can configure a physical partition by combining any SB and IOU irrespective of the
mounting location.
The PRIMEQUEST 2400E3/2800E3/2400E2/2800E2/2400E/2800E supports Flexible I/O.
For details, see

1.4.17 Memory Scale-up Board

Memory Scale-up Board is the board for expanding memory in PRIMEQUEST 2400E3/2400E2. Up to three
Memory Scale-up Boards can be installed. Using Memory Scale-up Board can expand memory up to 24TB
without increasing CPU.
For details, see

1.4.18 Virtual Support Virtualization Technology (VT) Function

PRIMEQUEST 2000 series supports the Virtualization Technology (VT) listed in the table below.
VM Support
VT-x CPU
VT-c
IO-AT
VMDq
SR-IOV

1.4.19 Management Board (MMB)

Management Board functions: Monitoring the hardware status, displaying configuration / error information,
partition management, network environment management and power control.
At least one MMB is required for operating the system in the PRIMEQUEST 2000 series. One more MMB
can duplicate the MMB in PRIMEQUEST 2400E3/2800E3/2400E2/2800E2/2400E/2800E; even if one of the
MMBs fail, the process can be continued with the other MMB.
Active maintenance can be carried out in an operation with duplicate MMBs.
For details on the MMB, see
'5.10 Flexible I/O Mode'.
'5.5 Memory Scale-up Board'.
Components
Intel ® CPU Virtualization technology
'VMX root mode and VMX non-root mode' are added in the existing
processor mode (rings from 0 to 3)
The merit of VT-x is low overheads of issue of privilege command by
Guest OS.
Intel ® Virtualization technology
VT-c is the general term for the virtualization support functions (VM
Assist) listed below.
CPU I/O Acceleration Technology (IO-AT)
On board LAN IO-AT indicates high speed I/O technology, which increases the
controller speed and efficiency of processing data and interruption.
- Intel ® QuickData Technology
- Direct Cache Access (DCA)
- Extended Message Signaled Interrupts (MSI-X)
- Receive Side Coalescing (RSC)
- Low Latency Interrupts
On board LAN Virtual Machine Device Queues (VMDq)
controller VMDq is a virtualization support mechanism provided in the Intel LAN
card. The hardware with VMDq contains a function that creates the
LAN-SW on the VMM when the NIC is shared by multiple VMs.
On board LAN Single Root– IO Virtualization
controller The SR-IOV is a PCI Express standard, having multiple functions in
the card, which directly accesses the respective functions from the
VM.
