- 1. VESK James Mackie (MD) How to Launch a Successful VDI Hosted Service using OpenStorage and Citrix XenDesktop
- 2. Quick idea on the VDI market Quick idea of the VDI market There's a lot of facts and figures on virtualisation, people tend to confuse these figures around server, desktop and application virtualisation. So here are some real figures on VDI The leading 5 desktop outsourcing companies in Europe are: HP Atos IBM CSC Fujitsu Leading 5 manage 13 million desktops Of which now 1.4m are virtual desktops So it's safe for us to say around 10 of desktops are virtual
- 3. VDI Firstly I just wanted to elaborate on the title, "how to launch a successful VDI hosted service“ There's now many different types of VDI. But it's important to differentiate and recognise between them as there seems to be a lot of confusion. Internal VDI deployments (Private Cloud) Usually consists of a cloud specialist consulting a large corporate Popular with large organisations who can afford the CapEx and have the in-house technical knowledge HVD, hosted virtual desktops (Public Cloud) TOTAL cloud, consumes all applications and data DAAS cloud connect (Hybrid Cloud) Non persistent Cyber security Interconnect required VESK (Virtual Private Cloud) Giving users their own control of their VDI
- 4. Case study VESK case study: Brixton council 550 users 185 applications Security & compliance Green Government CSR’s The problem we had IOPS. Microsoft say virtual desktops require 5-25 IOPS, we have seen desktops take 100 IOPS
- 5. Recent Storage implementation Head nodes HA / failover RAIDz2 JBOD’s SSD’s - Mirrored ZIL’s - L2ARC 72 x 2TB drives Over 140TB raw 1gbps switch 10gbps connect 6 gbps SAS cables 14U Low power 5
- 6. Problems encountered Upgrade to Nexenta 3.1 How many of you guys have upgraded to 3.1 ? Excellent new features, for us it's all about autosync pausing Now we don't have to resync 100's of TB of data over our interconnect Issues zpool needed upgrading some disk groups didn't copy across successfully Disk names became missing and state DEGRADED Pause on hourly sync, just a 3 second glitch Future expansion We just add a new SAN May mirror in future instead of RAIDz2 Why not dedup ? 2GB of RAM per TB of storage required
