BladeSymphony 1000 Architecture

 

Hitachi also offers Fibre Channel I/O virtualization for Virtage. This allows multiple logical partitions to 
access a storage device through a single Fiber Channel card, allowing fewer physical connections 
between server and storage and increasing the utilization rates of the storage connections. This is 
exclusive to the 4 GB Hitachi FC card.

Virtage also provides a virtual NIC (VNIC) function, which constructs a virtual network between LPARs 
and enables communication between LPARs without a physical NIC. There are two types of virtual NIC 
functions: one that only supports the communication between LPARs, which has no connection with 
external networks. The other is a part of the shared NIC function that realizes connection to the external 
physical network through the shared physical NIC.

Virtage enables multiple VNICs assigned to LPARs to share a physical NIC. This function takes full 
advantage of the connections between VNICs and external physical networks. The physical NIC shared 
between VNICs is called a shared physical NIC in the virtualization feature.

Hitachi provides secure and integrated system management capabilities to reduce the total cost of 
ownership (TCO) of BladeSymphony 1000 with Virtage. Hitachi offers integrated system management 
functionality with Virtage virtualization. Administrators can access the integrated remote console via IP 
to mange and configure the virtualized environments remotely. Virtual partitions can be created,
re-configured, and deleted through an integrated console screen that is remotely accessible.

An integrated shell console lets users access the guest operating system directly from the console 
screen for ease of use. The system also monitors CPU utilization rates and allows processor CPU 
utilization changes dynamically for partitions operating in CPU shared mode.
