1.4.12 Extended Partitioning

The PRIMEQUEST 2400E/2800E supports the Extended Partitioning function.
The Extended Partitioning function is the function which divides the physical partition by firmware in units of
CPU core. Low cost, high reliability and secure procedures are provided.
The features of this function are listed below.
- The granularity of the resource allocation to the partition is fine, thereby enabling effective usage of the
server resources.
- The CPU can be allocated in units of core.
- The memory can be allocated by one GB.
- Easier to set up than virtualization OS
- A device in the partition can be directly accessed from the CPU, without using a virtual device
The hardware resource allocation by using Extended Partitioning can be set in the MMB Web-UI.
For details, see

1.4.13 Dynamic Reconfiguration (DR) function

The DR function changes the resource configuration of a partition without rebooting the partition.
The PRIMEQUEST 2400E/2800E supports the dynamic reconfiguration function.
Remarks
The DR function operates only for the physical partition.
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 (C122-E175EN)

1.4.14 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 2400E/2800E supports Flexible I/O.

1.4.15 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
'5.2 Physical Partitioning
'5.3 Extended Partitioning'.
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 (R) QuickData Technology
- Direct Cache Access (DCA)
- Extended Message Signaled Interrupts (MSI-X)
- Receive Side Coalescing (RSC)
- Low Latency Interrupts
(PPAR)'.
