implementing NSX. – business wants to be Amazon-like. Do more with less. Abstract, Pool,Automation is key. Across compute networking and storage.
Both need access to same environment. how?
RBAC, integration with AD groups
Modify existing role for network admins and server admins are administrator
1. restrict per DVS. NSX groups for Network Admins. VMkernels, system traffic, etc for Server admins.
> network folder, modify permissions,
2. RBAC with a single DVS (preferred methode)
> just give read-only on a portgroup level to network admins. (like vmotion, mgmt, nfs, etc)
On a VM level, RBAC on VM’s. Network admins get access on Folder level (F5, LB, NSX). Server admin get no access/read-only
A lot of customers want to be Amazon-like. SDDC is a used for this. NSX is the SDN part of the SDDC model.
NSX momentum, over 150 customers.
How are these customers using NSX today: Three main use cases
1. Self-Service IT (Portal) – DevOps Cloud and On-boarding M&A
2. Data Center Automation – Micro-segmentation of App – Simplifying Compute Silo
3. DMZ Deployments
NSX is not a product, it is a platform. how?
Operations, Security, Physical + Virtual (L2 L3 gateway) Application Delivery (LB, Wan Optimization)
Service Insertion through Gateway, VTEP.
The VMware NSX Distributed Firewall can be used for micro-segmentation. There are no choke points and there is scale-out performance up to 20 Gbps.
It acts like firewall on the vNic. Each vNic has it’s own rule set. Performance is close to line-rate. Traffic Redirection is possible to 3th party.
Of course there is the Rest API.
DFW is a stateful engine. During a VMotion the state table is migrated tand is in place before the VM arrives on the destination host
If you use SAN pin groups in UCS manager. it wil translate to the NPV traffic map feature on the CLI. You can see that with the “show npv traffic-map” command on the FI (connect nxos)
show npv traffic-map
UCS-SB60-A(nxos)# show npv traffic-map
NPV Traffic Map Information:
vfc699 san-port-channel 100
vfc702 san-port-channel 100
npv traffic-map server-interface vfc699 external-interface san-port-channel 100
npv traffic-map server-interface vfc700 external-interface vfc697
npv traffic-map server-interface vfc701 external-interface vfc697
npv traffic-map server-interface vfc702 external-interface san-port-channel 100
put a N55-M16UP GEM card in slot 2 in a N5548UP and you just want FC on that module. You can just ‘poweroff module 2‘ and ‘no poweroff module 2‘ without having to reload the whole thing.
