VAAI for HP 3PAR storage performance whitepaper

3PAR VAAI Perf.pngLast week I found a white paper talking about VAAI on the P9500 and wrote a blog post based on it.  Today, I found a whitepaper titled "Reduce resource and storage bandwidth consumption - simplify and significantly" with a subtitle of "VMware vSphere VAAI for the HP 3PAR Storage performance benefits".  It has a great introduction to the VAAI primitives that can help improve performance so I thought I'd reproduce that for you on this blog post. 


Introduction to VAAI


The vSphere Storage APIs for Array Integration (VAAI) are one of the storage application programming interface (API) sets in vSphere 5.0. VAAI is an API that storage partners can leverage to enhance performance of virtual machine (VM) management operations by delegating these operations to the storage array. With hardware offload, ESXi hosts may perform certain operations faster and consume less host CPU and memory resources, storage fabric, and network bandwidth. VAAI includes high performance and scalable VM data path primitives. HP introduced VAAI support for the HP 3PAR Storage products starting with the HP 3PAR operating system(formerly InForm OS) v3.1.1 or 2.3.1 firmware release.

VMware VAAI best practices for P9500 and XP24000 Disk Array

P9500.jpgI came across a white paper written by our VMware integration team talking about best practices for the VMware API for Array Integration (VAAI) plug-in for the P9500 and XP24000/XP20000 disk arrays with VMware vSphere 4.1 and it didn't have the normal pub number and I couldn't find it on the web - so I thought adapting it here would make for a good blog post.  I'll have a link at the end where you can find info on using VAAI with vSphere 5.0.

New HP EVA improves capacity, performance and total cost of ownership

c02734161.jpgThe good news is that HP is continuing to invest in EVA P6000 Storage. We’re announcing a series of enhancements designed to help you optimize traditional and virtual workloads with new technology innovations. In a nutshell, these enhancements include:

  • New models, EVA P6350 and EVA P6550, with twice the cache
  • Increased addressable capacity now over 1PB
  • New drive options including support for 200GB and 400GB Small Form Factor (SFF) Serial Attached SCSI (SAS) Solid State Disk (SSD)
  • New 3TB SAS drive option for increased scalability
  • Integration with VMware vSphere Storage APs (VAAI)
  • Performance Advisor Software for intuitive, easy-to-use performance monitoring and troubleshooting interface



The new vSphere 5.0 VAAI primitives

Ok - last of my blog posts for today.  This one talks about some of the new VAAI primitives coming in vSphere 5.0. During the podcast,  I also talk to Kiran Sreenivasamurthy about the advantages that our HP 3PAR architecture has with VAAI.

VMware storage integration survey

In this post, I point to a survey being done by asking about VMware storage integration and take the opportunity to revisit what we've done in HP storage with VMware.
