Bring SAN to your lab – EMC vVNX part1 Installation

header-image-vvnxEMC has just announced availability of new version of software defined solution, mimicking hardware array VNX – vVNX Comunity Edition. What is more interesting it is free and without any limits for non-production use! In next few articles i’ll present capabilities of vVNX and check if it’s a viable solution for home lab.

To download vVNX go to this link.

[SG] 4.1 Identify Business Group roles and their specific privilege levels

A business group associates a set of services and resources to a set of users, often corresponding to a line of business, department, or other organizational unit.

Business groups are managed on the Infrastructure tab but are used throughout the service catalog. Entitlements in the catalog are based on business groups.

To request catalog items, a user must belong to at least one business group. A business group can have access to catalog items specific to that group and to catalog items that are shared between business groups in the same tenant. In IaaS, each business group has one or more reservations that determine on which compute resources the machines that this group requested can be provisioned.

A user can be a member of more than one business group, and can have different roles in different groups.

[SG] 1.2 Configure default tenant and any additional tenants

https://<your vRA ip address or name>/vcac
i.e. https://vra.home.lab/vcac

To configure tenant(s):

  • Logon using SSO admin credentials
  • You logged on as Tenant admin (by default SSO admin becomes first Tenant admin)
    TENANT 01Options which you can configure are:
  • Tenant tab
    • Add new tenant (green sign)

  • Branding
    Change look and feel of your tenant specific self-service portal
  • Email Servers
    Configure Email server
  • Event logs
    Check event logs

vCenter Server Appliance 6 the new way of configuration

With an update of vCSA to version 6, the way of configuration of server has changed. Before initial configuration has been done on Web configuration page (IP address of vCSA followed by port 5480). It is standard web based method for all Vmware appliance. With vCSA 6.0 and new installation method we are configuring most of the settings during process of installation. But what can we do if we want to change something.

Some of settings can be reached under Web Client -> Administration -> System configuration.

vCenter 6 config 01


In nodes you can configure settings for your vCenter Server.
In services some of the settings for services running on server.

Unfortunately some of the settings are missing, includes NTP configuration. All admins know ho important is your time synchronization.

So lets configure this settings.

  1. SSH to your vCenter Server
  2. Login with root credentials
  3. type command

    When you start typing, use double ‘tab’ key to auto-fill command, pressing it again will show you all command from specific namespace

    i.e ntp
    Command> ntp
    ntp.get                          ntp.server.delete ntpq
    ntp.server.add          ntp.server.setYou should see your current NTP settings
  4. If NTP server is missing, add new server
    ntp.server.add –servers <servernsame>
  5. Change timesync setting to use NTP
    timesync.set –mode NTP
  6. After all changes check NTP config again
  7. You should see Status: Up and name of your NTP server.

[SG] 1.1 Differentiate vCloud Air solutions

Access to vCloud Air portal is here.

Vmware Cloud offers various services. To check all of them go to the tab ‘Service Offering’. Three core services are:

  • Dedicated Cloud (Physicaly isolated)
  • Virtual Private Cloud (Logically isolated, Guaranteed resources)
  • Disaster Recovery (Logically isolated, multi-tenant, warm standbay, asynchronus replication, failover solution)
vCloud Services
Dedicated cloud Virtual Private Cloud Disaster Recovery Cloud
vCPU 30 Ghz 10 GHz 10 Ghz
vRAM 120 GB 20 GB 20 GB
Storage  6 TB 1 TB 1 TB
Public IP 3 supported 2 included 2 included
Network 50 Mbps (burstable to 1 Gbps) 10 Mbps (busrtable to 50 Mbps) 10 Mbps (busrtable to 50 Mbps)

Another option is Virtual Private Cloud on Demand, characterized by no CAPEX involved, you are paying for resources on demand. Resources are metered by minute, billed on monthly basis.

Storage Services:

  • SSD tier
  • Standard tier

Each Cloud option can chose between both of the storage services.

  • Additional storage capacity is added incremental in 2 TB and 6 TB chunks.
  • Storage interconnects is 10 Gb iSCSI with 20 Gb link aggregation.

Availability Services:

On Dedicated and Virtual Private Cloud

Data Protection – backup VMs and vAPPs. Includes features such as:

  • Self-Service registration
  • Scheduling and retention policies configuration
  • In-place & Out-of-Place Restores
  • Reporting and dashboard

Disaster recovery – provides vSphere replication to other vCenter or vCloud DR. Includes features such as:

  • Fully encrpyted replication traffic
  • Failover testing
  • Failback features with VMware vCloud Connector
  • RPO 15 min

Networking Services:

vCloud Services
Dedicated cloud Virtual Private Cloud
Virtual DC multiple single
Edge Gateway multiple (each with own networking profile & configuration) single

Edge Gateways characteristic:

  • deployed with active-standby configuration (HA)
  • Supports up to 20 networks (9 routed)
  • Supports Firewall, NAT, Load Balancing, Site-to-Site VPN

Support for Direct Connect – dedicated network connection provided from network SP. Dedicated cloud support 1 and 10 Gbps connection, when Virtual Private Cloud 1 Gbps.

Most of the information comes from vCloud Air Fundamentals training.
