These are just some questions I asked related to the product during sessions and I will
Why use more than one workload domain?
- Horizon view (VDI)
- Separate customer environment
Are network shared by default between workload domains?
- No, individual VSAN, VXLAN networks created.
Can you setup network with universal logical router between workload domains?
When you enable vROPS and or VRLI, does it create a new instance for each workload domain?
- No, add-on applications like vROPS/VRLI is shared between all workload domains.
When login can see all the vcenters and hosts.
During initial configuration of Cloud Foundation environment through VIA (evo-rack imaging appliance), how is naming resolution taken care of?
- DNS/naming resolution is handled by vrack management appliance.
- Cloud Foundation uses own naming convention (can be changed)
- ESXi hosts connected through IP address to vCenter server in each domain workload.
vSAN ready nodes
- 8 minimum
- Technically can be 6, but 8 provides the necessary recommended redundancy for VSAN.
- 4 nodes for Cloud Foundation management cluster and other 4 for first VI (virtual infrastructure)
What if problem occurs during the installation process?
- Process will stop, logs can be reviewed, changes can be made to installation scritps and process re-run.
- Can also install/reinstall to individual ESXi host
What are the resource selection options when creating a workload domain?
- Only per physical hosts (4 min)
- Workload domains cannot be shared by for instance a resource pool
Is tags/ storage profiles supported?
Yes but it is not available natively within SDDC manager. Storage profiles would have be create in vCenter server within each workload domain.
Are all vCenter Servers from each workload domain configured with advanced linked mode?
How are PSCs configured?
- 2 x PSCs
- First PSC assigned management
- Second PSC assigned to first VI (virtual infrastructure) workload domain.
- Each additional workoad domain will round robin between the 2 PSCs.
- Uses default vsphere.local domain name.
- SDDC manager is connected to PSC.
ESXi host profiles used when deployed?
- Not sure and will update when I have any answer.
Can you attached other storage devices?
- Can setup NFS datastores through vCenter server.
After deployment, how do you retrieve your application addresses so can login to for instance your vCenter Server, NSX Manager etc?
- Management info tab provide in SDDC manager which shows all management software components and provides hotlinks to each!
- Not sure and will update when i have any answer.
How are passwords handled?
- Cloud foundation will provide an application that will reset all the passwords which includes all hardware and software components.
- It will also create a master password which is only available to customer.
Support max up to 8 racks!(192 servers)
- When you add a new rack some redundant spine switch are added to interconnect racks.
- Min 4 hosts management
- Min 4 host infrastructure
Here are some information on the physical requirements for Cloud foundation:
- Redundant power
- 8 to 24 VSAN ready nodes
- Management switch
- 48 x 1GB
- Redundant Top-of-Rack switches
- 48 x10GB
- 4 x 40GB (2 to each switch)
- Redundant Spine switches (only require if more than 1 rack)
- Multi rack config
- 32 x 40Gbps
- Automated installation and configuration of physical networking.
- Integrates with existing data center network infrastructure
- Uplink fully compatible to existing switches (Cisco, juniper)
- vMotion shared across all workload domains
- VXLAN shared across all workload domains
- Different VLANS for each network
Different VLANs created for each workload domain:
- Non-routable management VLAN
- Public management
- Corporate external
Switch count for 1 rack?
- 1 x management switch
- 2 x top-of-rack switches
Switch count for 2 racks?
- 1 x management switch
- 2 x top-of-rack switches
- 2 x spine switches
VMware will also be providing a wire map for implementations.
What is a workload domain?
- A Workload domain consists of ESXi, vCenter, VSAN and NSX
- SDDC Manager is used to create a workload domain which is wizard driven with automated host selection
- There are current 2 different workload domains which can be deployed:
- vDI workload domain
- VI workload domain (Virtual Infrastructure or can call it IAAS)
- Requires about 45 minutes to deploy which is crazy if you think about it since I installs ESXi on each host, install and configure networks, physical ports, vCenter Server, VSAN and NSX and have it ready to just deploy your VMs.
- You can deploy as many workload domains as required.
- Seamless expansion with additional hosts
- Policy based control:
- Capacity, performance, availability (networking, security)
- Automated deletion and reclamation of capacity
- Workload domain can be expanded, deleted as well as patched/updated through lifecycle management.
VIA (evo-rack imaging appliance)
- VIA was pretty awesome to see! I do hope in the future that this product will be integrated into SDDC manager so you don’t have to switch between the two.
VIA provides a UI from where all the necessary information is entered to setup the initial environment. It will install the ESXi hosts, vCenter Server, VSAN and NSX software as well as all the necessary networks.
High level steps to bring up SDDC:
- Physical deployment
- Fully assembled rack arrived at customer
- Power and networking connect per site survey
- Power-on validation
- SDDC manager and HMS brought up
- System check against known good inventory
- DOA, other discrepancies identified
- Customer info input (Collected during site survey) (json input)
- DC parameters, DNS, AD, NTP etc
- IP address for vMotoin, VSAN, VXLAN
- Management cluster
- SDDC manager
- SDDC stack brought up
- VSAN datastore created
- Vrealize products configured
- Management packs installed and configured
- HA for management cluster configured
- SDDC ready to use
- Workload domains created
- VM brought up
VMware announced yesterday the upcoming release of VMware Cloud Foundations which is its first SDDC solution and provides a natively-integrated infrastructure stack.
I was one of the lucky ones to get invited and attend VMware’s first ever bootcamp session on VMware Cloud Foundations and it did not disappoint. We got some first hand knowledge of the product and its offerings and here is what I learned.
To start off with what exactly is Cloud Foundations.
- Its a software defined solution which integrates vSphere, VSAN and NSX into a single platform.
- It provides a common foundation across clouds with flexible deployment options and primary focus is on simplifying deployment and operations.
- Cloud foundation can run in private and public cloud.
Both private and public cloud faces a problem of availability with being able to move data across private and public cloud. This is where Cloud Foundations can build a common base and with the use of NSX can create a universal transport zone which provides the connectivity necessary to move your workload between sites.
Two different deployments:
- Customer self-deployment onsite
- Factory pre-loaded
- Ready systems:
- Qualified VSAN ready nodes – DELL, QCT, HP
- Qualified networking – Cisco 9k, Arista 7500 (Northbound L2,L3)
- Integrated systems:
- Cloud service provider
- IBM SoftLayer (Q3 2016 GA)
- Vmware vCloud air Network (vCAN)
- Vmware vCloud air
In my next couple of posts I will provide a bit more detail on the Cloud Foundation private cloud components and installation. These posts will only cover my notes from the bootcamp session so apologies for any mistakes and do let me know if you find any. I will also update the posts in future when more information is available.
