I’ve been using VMWare vSphere for over 5 years and vCloud Director, vCOPs suits and vCAC for almost 2 years.
vSphere: vMotion, DRS, Storage DRS, HA, FT, Storage profiles, dual heartbeat in cluster environments.
vCloud Director: Building and managing Private and Public Clouds
VCOps: Drill-down troubleshooting and monitoring vSphere and vCloud environments
vCAC: Provisioning single/multi machine and relevant infrastructure using Blue-Prints, Integration of other public cloud providers like Amazon etc using respective Endpoints
Lately, features like vSAN, vFlash etc. in the 5.5 version of vSphere.
Improvements To Organization:
vSphere: vMotion (ease of migrating VMs from one host to another), DRS (ease of migrating VMs from one host to another automatically to balance out workloads in cluster environments), Storage DRS (ease of migrating VMs from one Datastore to another automatically to balance out workloads in storage cluster environments, HA (High availability is ensured by the newly developed FDM construct. FT (Ensuring 100% up-times reliably), Storage profiles (to bifurcate storage tiers accoring to the SLAs etc., dual heartbeat in cluster environments for confirmed Host isolation avoiding false alarms/isolation responses; key to maintain SLAs.
vCloud Director: Effective and robust way of building and managing of Private and Public Clouds. Tenants/Organizations can be effectively created and managed using vDCs. Provider Datacenters can be created and managed through Provider vDCs.
vCAC: Provisioning single/multi machine and required infrastructure using Blue-Prints, Reservation/Allocating resources and Business/Provisioning groups and self-service portals automate the process and approval oriented provisions. vCloud Automation Center has a multi-vendor approach from the outset; Integration of other vendors cloud infrastructures like Amazon etc using corresponding to the respective Endpoints.
VCOps: Drill-down troubleshooting and effective Monitoring vSphere and vCloud environments
Lately, features like vSAN, vFlash etc. in the 5.5 version of vSphere has increased the viability of large Storage and Multimedia intensive projects.
Room For Improvement:
FT: Still just 4 VM’s/Servers supported. Single processor constraint still exists.
HA: Still 32 node HA cluster supported.
Deployment, Stability, Scalability Issues:
Yes; Hyper-V. The reason for switching was indeed the efficiency crisis with Hyper-V resulting in subsequent service issues ->service tickets-> increased number of troubleshooting tasks -> increased number of breaches in the SLAs
Customer Support and Technical Support:
I give them a 5-star rating.
Straightforward, as it’s designed at a more abstract level.
Vendor as-well-as in-house. I give them a 5-star rating.
Well surpasses expectations. Also depends on the factors like Max Consolidation Ratio; 1.5 VM per Core
Depends on the licences purchased per ESXi, vCenter for vSphere and licences purchased for vCloud Director, VCOps suites.
Go for it. Follow the bottom-up approach; VMware’s Implementation Guide for each product and you will sail through.
