Yes you can. Using the great guide by Bernie Baker on Chad’s site (virtualgeek.typepad.com) is a great start.

Something to put on the list for sure. Biggest issue is unless requesting massive amount of data the VMDirectPath or PVSCSI stuff just doesn’t pay off.

And since the intention is home lab and not production, big throughput is lower on the feature list than lower access latency and fixing the write issues.

Thanks for the feedback

Thanks for all the comments everyone. For those with suggestions on the eth0,eth1,eth2 setup on the Control Center: Yes, the extra two IP’s are not needed. This was left over from the previous version. The new version only uses one interface for the CC (on eth0) and will also has about 1/3 the response time on the CGE’s do to binding issues.

This change didn’t make this release because I didn’t have time to fully regression test the changes (eth2 to eth0, new wizard, etc)

Good to see so many smart people spotting stuff so quickly. Especially the EMC peeps

Nick,

What is the point of 3 IP addresses? You configure them on a Control Station, not on datamovers… The CS is ok with just one — for web access, whence it is the DM that needs to be used for data.

I guess I am asking for quick FAQ

Nick,

I can’t get to the FTP server. Is it down?

Hi Nick,
Thanks for the effort, it was decisive for me to jump in VSA!I Have exactly the same network troubel than Mukul just above, but using the Workstation version. But in fact the comment leaved by matt is also correct: you do not need to set the interface before using VSA. My 10 cents for people suffering poor performance on Workstation: 64 bit OS is a must and think also to enable Virtual process features in Bios!
Thanks

Hi Nick,

First of all thanks for all the efforts you did. All the installation went through good (on ESX 4, I used OVA download)but after the final reboot network interfaces for nfs and cifs did not get configured and so do remaining all settings. I had to configure network manually.

Not sure is that normal or you want to have a look at it.

Thanks

Nice one Nick. Works like a charm.

Can I offer a suggestion to the initialization script?
Setting an IP address on eth0 and eth1 isn’t necessary for the NAS to be able to use the ports as cge0 and cge1.

I’ve modified my ifcfg files for eth0 and eth1 to look like this and it has no problems.

/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static

/etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
ONBOOT=yes
BOOTPROTO=static

Hi Nick,
This is UBER work! Thx for that and keep them coming
Do you think it’s feasible to add/replace the current LSI Logic SAS controller with a VMDirectPath IO disk controller (dedicated one obviously) to make this Celerra VSA even uber faster?
Thx,
Didier

Thanks, really fast and easy installation and configuration, I use option 2. Celerra VSA – UBER for Workstation/Fusion, can I do a SRM config ?
