Thank You VMUG Leaders!

+AgendaThe Home Lab Backstory - Long, Long
ago in a galaxy called 2003….
Former vSphere Setup
CH-CH-CH Changes - vSphere5.1 Setup Compute Network Storage
vCD Lesson Learned…
My Lab To-Do List…

+What is vCloud Director?
![Page 6: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/6.jpg)
+The Home Lab Backstory - Long, Long ago in 2003…
My first attempt with ESX 2.0/vCenter 1.0
Location: Under my desk
Girlfriend Impact: NIL
![Page 7: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/7.jpg)
+The vCloud Suite: SDDC Era Virtual Appliances where possible/necessary
vCenter Server Appliance (VCSA) Feature Parity with Windows version Switch allowed me to completely reconfigure resources around
vCloud/SDDC agenda Reduce “infrastructure VM” footprint Beware of plug-ins; Support for the web-client (e.g. NetApp VSC)
vCloud Director Virtual Appliances (vCD-VA) Use built-in Oracle XE DB Dead easy to setup (No Packages, DB setup) Beware: No multi-cell, No migration Beware: Demo only; Labs; Training purposes…
vShield Manager Virtual Appliance (Mandatory)
vSphere Replication Appliance (VR)
vSphere Data Protection Appliance (vDP)

+vSphere5/SRM5.0/View5.1 Era – SRM 5.0 Period (2011)
Hello 2x Dell Equallogics Hello 1x NS-120 & 1x NS-20 Hello 2x NetApp 2040s Hello massive colocation bill!!!
VMware Employee Period (2012) >>>>>>>>>>> HomeLab & ProLab Merge Goodbye EMC Goodbye 2xPDU Hello 24U of extra racks space Hello to 14 AMPs extra power!
Location: Quality Colocation
Costs: £870 GBP, $1,300 USD
Girlfriend Impact: Married 2013,4th May

+Virtual Silos The VMware Cluster as the New Silo?
Discrete Blocks of: Compute Network Storage
Q. Why do we like silos?
Q. Why do we hate silos?
![Page 10: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/10.jpg)
+Compute…
![Page 11: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/11.jpg)
+Compute Continued…
One Site; Two Clusters
“Infrastructure” Resource Pool – No Management Cluster
GOAL: Maximize Resource; Setup Tiered Clusters
Decisions: Different CPU types forced DRS separation Gold Cluster = HP DL 385s
WHY? = More memory & FC connected to SAS storage Silver Cluster = Lenovo TS200
WHY? = Less RAM, Only 1GP pipe to either SAS/SATA on NFS/iSCSI
![Page 12: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/12.jpg)
+Storage…
![Page 13: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/13.jpg)
+Storage Continued… Destroyed Datastores!
Except Infrastructure datastore Templates Software (iso, templates, miscs)
Originally a much more complicated layout – 7 Tiers!!!
4 Tiers 1. Platinum (NetApp, FC, SAS, SnapMirror – 5min RPO) 2. Gold (Dell, iSCSI, SAS, Replication – 1hr RPO) 3. Silver (NetApp, NFS, SATA, Datastore Cluster, 3x300 GB, Thinly Provisioned) 4. Bronze (Dell, iSCSI, SATA, Thinly Provisioned)
vSphere Replication for Replication from 3>4 or 4<3
![Page 14: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/14.jpg)
+Storage Anxieties… Many Organizational Tenants sharing the SAME datastore
What about Site Recovery Manager? What about performance – Capacity management isn’t the
issue
With Array-based Replication (ABR) One Failover to rule them all? No per-vApp Failover No per-Organization failover
Solutions? Platinum/Gold datastores per-Organization vSphere Replication VMware vVols
![Page 15: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/15.jpg)
+Network…
![Page 16: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/16.jpg)
+Network Continued… Goodbye Standard Switch
Struggle to provide redundancy/separate with the “Combo Approach”
Many of the Adv features of vCD require Distributed vSwitch
Classical Approach: Two DvSwitches
One for internal vSphere Networking (vMotion, IP Storage, FT, Management)
One for Virtual DataCenter Backed by two VMNICs each…
![Page 17: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/17.jpg)
+Network Anxieties… All my Provider vDCs share the SAME DvSwitch
What about “Fat Finger Syndrome”?
How realistic is that?
Time to re-examine “Best Practices”
Do best practices represents an ideal OR an ideal filtered through the limitations of a technology Provider vDCs in vCD 1.x – One Cluster, No Tiering of
Storage Provider vDCs in vCD 5.x – Many clusters, Tiering of Storage
![Page 18: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/18.jpg)
+Lesson Learned When thinking about a Provider vDC
All the resources matter Compute + Storage + Networking By far the easiest for me was compute
But my “Gold” cluster has no FT Support Prepare to make compromises/trade offs UNLESS all your hosts are the SAME
VXLAN needs enabling on Distributed Switches via vSphere Client Prior to creating a Provider vDC
Watch out with VMs already on the cluster – vCD ESX Agent Running existing “infrastructure” VMs on a cluster Stops the install of the vCD Agent Has to be done on per-ESX host basis (easy)
![Page 19: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/19.jpg)
+More Lessons Learned…
Get your VLANs sorted BEFORE you use them in vCD…
Beware of Orphaned VLAN references in the vCD Databases

+Work out your IP before you start!“Wrong”
192.168.3.x – “External Network” 172.168.x.x – “Organization Network” 10.x.x.x – “vApp Network”
“Right” 10.x.x.x – “External Network” 172.168.x.x – “Organization Network” 192.168.1.x – “vApp Network”
Keep it simple – whole ranges dedicated
![Page 21: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/21.jpg)
+IP Ranges can be tricky to change Even with vApps powered off – options unavailable
Gateway Address Network Mask
Resolution involves admin: Add new vApp Network Remap all VMs to new vApp Network Remove old vApp Network
![Page 22: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/22.jpg)
+vApp Networks & Edge Gateway Every vApp Network you create:
Creates a vCNS Edge Gateway Consumes resources
Solution Create two vApps per Organization TypeA: One on the Organization Network TypeB: One on its own vApp Network Power off the Type B vApp to save resources Beware of static MAC/IP on Power Offs
![Page 23: How I reshaped my lab environment](https://reader034.vdocument.in/reader034/viewer/2022051513/5466b1d3af79599b498b56c0/html5/thumbnails/23.jpg)
+Establish a meaningful naming convention…
I KNOW EVERYONE SAYS THIS, BUT IN A HOME LAB DON’T YOU CUT CORNERS SOMETIMES?
<ORGNAME><NetworkType><Purposes> CORPHQ-OrgNetCorp-EdgeGateway CORPHQ-vAppNet-WebGateway Makes screengrabs, documentation & troubleshooting
soooo much easier… Register Edge Gateway devices in DNS… Helps with SysLog – watch out for stale DNS Records…
