What is the difference between LSI Logic SAS and VMware Paravirtual?
What is the difference between LSI Logic SAS and VMware Paravirtual?
LSI Logic SAS – This is an evolution of the parallel driver to support a new future facing standard. VMware Paravirtual (aka PVSCSI) – this vSCSI controller is virtualization aware and was been designed to support very high throughput with minimal processing cost and is therefore the most efficient driver.
What is a Paravirtual SCSI adapter?
PVSCSI adapters are high-performance storage adapters that can result in greater throughput and lower CPU utilization. PVSCSI adapters are best for environments, especially SAN environments, where hardware or applications drive a very high amount of I/O throughput.
What is LSI SCSI?
LSI SCSI Cards These allow you to connect to your scsi hard drives directly or attached external scsi device to your computer / server. Some of the cards also have integrated raid for simple raid 0,1 support.
How do I change from LSI Logic SAS to VMware Paravirtual?
How-to safely change from LSI Logic SAS into VMware Paravirtual (on boot disk)
- Add a small, thin provisioned disk to the VM – 1GB in size is sufficient.
- Choose a 1:0 SCSI node (as on the image below).
- Then select the newly added SCSI adapter and click the change type button to select VMware paravirtual.
Which is better VMware paravirtual SCSI controller or LSI Logic SAS?
The use of the VMware Paravirtual SCSI controller performs a little better then the LSI Logic SAS SCSI controller. The results of above are within the virtual machine, with Xangati i was able to measure from the outside. The following picture will show the light better performance of the VMware Paravirtual SCSI controller,
What’s the difference between pvscsi and LSI Logic parallel?
PVSCSI and LSI Logic Parallel/SAS are essentially the same when it comes to overall performance capability. PVSCSI, however, is more efficient in the number of host compute cycles that are required to process the same number of IOPS.
Which is the best SCSI controller for a VM?
The standard controller in almost every VM is the LSI Logical SAS SCSI controller. This controller is recognized and supported by every guest operating system without additional drivers. It is suitable for almost any workload that does not have large I/O requirements.
Which is BusLogic parallel SCSI driver for Windows XP?
Windows XP uses the BusLogic Parallel SCSI driver and the results are acceptable. With Windows 7 the commonly used controller is the LSI Logic SAS controller. Which is selected automatically when creating a virtual machine of this type.
