need some idea to implement VDI project

Hi people,

Apart from replacing the old aging desktop fleet hardware, what are other scenario where VDI can be helpful ?

at the moment I can only think about replacing the dedicated DR suite in the offsite location with the VDI so that the user can connect to the DR desktop from virtually anywhere with Internet connection.

Any kind of help and response would be greatly appreciated.

Thanks.

I would also check the following Whitepaper, which compares and contrasts VDI...

Thanks for the quick reply, what I'm trying to achieve now is to get rid of the dedicated off site DR suite which is currently sitting outside of the city far away in a suburbs with around 40-60 workstations which is now about 3 years old. paying this building lease itself is costing me more than $100k per year.

So my goal here is to simplify the DR process by eliminating the traditional DR scenario where users must be in that offsite DR suite.

my current idea is to implement Citrix VDI - XenDesktop so that user can access the environment through any internet capable PC.

Yes, I have read the VDI smackdown doco, it sounds great to implement VDI.

one other scenario that I can think of is to replace the current Windows Server 2003 terminal server which is used by 20 users at the same time configured as 2x Unicast NLB cluster nodes.

replacing 16x Windows XP VM which is currently used as jump boxes for remote vendor support to our business critical application. Highly secure Windows XP SOE with tight GPO and strict firewall rule access on each VM.

so if anyone can or know any good reason on top of that examples, feel free to share it here.

Thanks

What type of SAN do you have??? Also have many disks per enclosure

I have the old EMC CX4-240 array and also the newer model EMC VNX 5300 array.

yes It does have 15 disk per DAE ranging from 7200 rpm SATA-II up to 15k rpm FC-SAN

No offence but 15K FC drive are not going to give you the IOPS to full support a VDI environment

So should I use SSD and data deduplication at the Block level ?

Ideally you should have your storage vendor or HP, Dell etc.. come in and evaulate your environment and give you recommendations on a VDI storage solution that would best fit your needs and future growth.

Wow. I've never thought that before.

Smart idea, because this is for just 40-50 users login at the same time during the DR test scenario, I guess using Windows Server 2008 R2 RDS + Citrix XenApp is supposedly cheaper to host it on Vmware ESXi 5.1

So how about the licensing pricing in overall ?

Microsoft Windows 7 desktop OS + VDA license vs. Windows Server 2008 R2 / 2012 RDS CAL
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

What do your users require RDS (sessions) or VDI (virtual machines) ?

i believe he users don't really care as long as they can resume their daily activity during the DR situation, so in this case I assume that the Windows Server 2008 R2 with RDS, the app can then delivered by Citrix XenDesktop while enabling some compatibility mode for the old legacy terminal application which talks to the mainframe.

I would opt for RDS (sessions) in a DR situation, this is what we have setup for many companies, for DR at new offices. (in case the offices were also destroyed!).

I said RDS in my very first answer. Why overcomplicate it?

You could put in RDS servers and if you want an RDS web gateway. Users can log onto the gateway and get their RDS connections.

You can even effectively load balance RDS these days.
