Technical Track - What's new in VI 3.5

Session speaker was Leena Joshi and she give us an overview of 3i and 3.5
for 3i we have:
  • compactness, 32 MB footprint
  • architecture only, no installation needed
  • wizard for deploying
  • syslog stored in memory and tools to analyze it
  • Distribuited Power Management (consolidate workload, place unneeded servers in standby and bring servers back online - minimizing power consumption and with no disruption of te VMs)

for 3.5 we have:

  • Update manager (scan and remedies online and offline VMs and online ESX hosts, snapshot VMs before patching, integrated with DRS)
  • Storage vMotion (FC only, zero downtime to VMs, LUN indipendent): this feature is not integrated with Virtual Infrastructure Client (...yet)
  • HA now support up to 32 hosts cluster, with proactive cluster confcheck. As experimental feature there is individual VM failure monitoring
  • VCB now support backup on iSCSI, NAS and local storage; you can use a virtual machine to run VCB and use Vmware Converter to restore the VMs.
  • New OS support: Vista and Ubuntu
  • up to 64 GByte of memory per VM and up to 256 GByte of RAM per host
  • support for ethernet up to 10 GBit and Infiniband

There are a lot of benefit in application performance due to:

  • Paravirtualization (now just for Linux, paravirt-ops with kernel > 2.6.21) that make guest OS virtualization aware: the major benefit are on large database, multiprocess applications, file server and web server because of net and disk I/O and context switching are better managed
  • Large memory pages
  • Network support for TCP segmentation Offload (reduce CPU overhead) and Jumbo Frames (with Jumbo Frame hardware enabled) with benefits on backup over lan, webserver, Citrix server and iSCSI
