Enhancement in VSphere 5.5: ESXi 5.5 Hypervisor
Enhancement in VSphere 5.5:
Currently we have VMware 6.0 introduced, still we have our time to review on 5.5 release enhancement. Later I would like to post on VSphere 6.0 Big Performance Gains.
Here we are quick review of VMware VSphere 5.5 feature enhancements in little brief.
ESXi 5.5 Hypervisor Enhancements:
- Hot-Pluggable PCIe SSD Devices
PCIe SSDs can used as storage cache or as primary storage devices. It has major features and benefits comparing to another storage device.
Here we have list of features includes.
- Scalable Performance, Better power management, Lower latency data transfers, Lower overhead, Advanced Error Reporting, Maximized interconnect efficiency, Native hot plug capability and Hardware I/O virtualization.
Now VSphere 5.5 version release with great benefits and running the ESXi server with PCIe SSD with Hot-pluggable (hot-add / hot-remove SSD devices while a vSphere host is running).
- Support for Reliable Memory Technology (ESXi error isolation)
VMware enables the ESXi server to use the region of system memory to optimize the placement of VMkernel and critical components (hostd and watchdog) in the fault resilient region of the system memory and makes ESXi robust against memory errors.
- Enhancements to CPU C-states
Now VMware DPM also uses ACPI states (deep processor power state (C-state)) to reduce power consumption of your ESXi hosts. The basic idea of these modes is to cut the clock signal and power from idle units inside the CPU. The more units you stop (by cutting the clock), reduce the voltage or even completely shut down, more energy you save, but more time is required for the CPU to “wake up” and be again 100% operational.
- New HW version release
VMware released new HW V10 LSI SAS support for Solaris 11, support for new CPU family, new advanced host controller interface(AHCI) can support to SATA, SCSI and IDE controllers in the VM. (new controllers supports with new guest OS: all MAC guests, Linux 2.6.29 and later kernels and Windows Vista and Later).
- Expanded vGPU Support
support for AMD GPUs (in addition to NVIDIA), automatic (switch between SW and HW rendering), hardware and software rendering modes
- Graphic Acceleration for Linux Guests
graphic acceleration is now possible for Linux guest OS: Ubuntu:12.04+, Fedora:17+ RHEL7
I will continue posts on VCenter enhancements….
