VMworld 2013 – Ask the Experts vBloggers (My Notes)

Rick Scherer (EMC) Duncan Epping (VMware), William Lam (VMware), Scotte Lowe (VMware), Vaughn Steward (NetApp)

First Question was the positioning NSX from the two operational teams.  Basically, if the relationship between the server team and networking team is already strained then what impact will NSX have. And what size environment is it positioned.

Scott: Responded by basically saying the political issues will not disappear and the network team has to be involved in the creation of policy for the virtual network.  It will initially be positioned for the large environment.


Question: What does the underlying network look like? Is it simple or complex?

Scott: NSX doesn’t de-emphasize the importance of a solid underlying network.  You still need enterprise hardware.  NSX is just decoupling the management functionality from the hardware.  The switching fabric still needs to be robust enough to support the needs of the infrastructure.


Question: vSphere 5.5 maximum limit is now 62TB but what impact will that have on the VMFS heap size.  Basically, the overhead

Duncan: VMFS, will support larger heap size.

Vaughn: File systems such as NFS help eliminate these issues as well.


Question: How does Site Recovery Manager (SRM) play with Virtual SAN (vSAN)

Duncan: SRM and vSAN are fully integrated.  The Recover Point Objective (RPO) may be an issue and vSAN doesn’t support synchronish replication.


Question: Will Hybrid vCloud support Recovery Point?

Duncan: There is no current plan to support Recovery Point

Vaughn: They have customers using vCDS to replicate to AWS so; it’s not unreasonable to see a solution working with vCloud.


Question: Is vSAN write-through caching?

Duncan: Yes

Question: Will NSX be able to reaching down and control both the physical and virtual layer?

Scott: New solutions from VMware partners now integrate directly with NSX to allow for the mapping to a logical port.


Question: What top tips can you give to the audience for our careers?

Vaughn: Move away from LUN’s and Pathing and etc and start to embrace API based on profile driven storage.

William: Focus on automation.  Today’s demo at the keynote focused on automations.

Duncan: Who do you get in one of these chairs? Read, talk to customers and write down stuff via a blog or community forums.

Scott: Be willing you challenge yourself and move out of you comfort zone.  Attempt to breakdown the silos.

Vaughn: Help move the needle by helping others learn the new technologies.  Help others help themselves and you’ll be up here.

Rick: He finds that he learns more when he teaches.  It’s a great time overall to be in IT.  The silos are not going away.  There will be SME’s in each silo. The virtualization admin will evolve to the Cloud Admin.  The hardcore VM admin needs to get familiar to orchestration/automation.


Question: What workload would be more suitable for the Low/High Latency setting for VM settings?

William: As far as he knows VoIP workloads.

Duncan: Don’t change the advanced settings unless directed by support

Vaughn: Same for NetApp.  Resist the temptation to tune advanced features.


Question: Can the vSAN mirror to split to say a Linux server?

Duncan: No, it’s a proprietary solution and doesn’t support this type of implementation especially in the 1.0 version.


Question: Is vSAN a BYOD solution for say 3 large host.

Duncan: The platform wasn’t intended for this use case but it’s capable to do so.


Question: There seems to be two different NSX products, an vSphere product and the traditional Nicira solution.

Scott: NSX is one solution but may be delivered two different ways based on the customer’s environment.  An pure vSphere environment will get one (distro) while a multi-hypervisor
