Virtual Server Deployment Model

Unlock the True Promise of Virtualization


Think you’ve already consolidated your SQL Server environment? Let DH2i show you how much more you can do. Whether you’ve taken an unlimited virtualization approach, with all cores licensed for SQL Server Enterprise edition, or a per-VCPU approach (4-core minimum license per VM), DxEnterprise can help you save substantially on licensing costs, reduce VM sprawl and improve datacenter manageability. All with an easy install. DxEnterprise can also pull an already-consolidated Docker environment into its advanced high availability framework and stateful containers can failover between hosts while all persistent data remains intact.

Your Virtual Infrastructure Can Consist of Any of the Following Elements
  • SQL Server 2005 or newer, any edition
  • Windows Server 2008R2 or newer, any edition
  • Ubuntu 16+, CentOS 7+, RHEL 7+
  • Oracle Database 11gR2 or newer, any edition
  • Docker, any edition
  • Industry-standard x64 servers
  • VMware, Hyper-V, or Xen
  • Any IP networking fabric
  • Fibre Channel, iSCSI or InfiniBand SAN storage
Virtualization Challenges for Unlimited and Per-VM Approaches

1. Unlimited virtualization comes with a hefty price tag

Unlimited virtualization requires SQL Server Enterprise edition and Windows Server Enterprise edition—both at ~3 ½ times the cost of Standard—and requires Software Assurance for mobility, which demands an annual annuity of an additional ~3 ½ times the cost of Standard edition. Unfortunately, this approach also comes with substantial challenges:

  • One-OS-per-application best practice leads to OS sprawl and all its related management headaches
  • Hypervisor overhead slows performance
  • Ecosystem lock-in, with no ability to change as requirements change
  • Quality of service (QoS) is tied to the machine, not the application
  • No application-level HA—server virtualization only protects against infrastructure faults
  • Patch/update challenges are the same as physical
  • Requires all the cost up front

2. Per-VM approach leads to sprawl with new SQL Server licensing

Despite the popularity of pay-as-you-go virtualization, this per-VM approach has challenges as well. Today’s SQL Server licensing requires that each virtual datacenter project take a minimum of four cores per box to handle its SQL Server load, even though in most cases the workload doesn’t require that much horsepower. Datacenter sprawl quickly occurs, with projects billed at much higher software costs than necessary. Mobility rights require Software Assurance, for an additional budget hit.

InstanceMobility with DxEnterprise Offers a Better Approach

DxEnterprise gives you InstanceMobility that lets you stack instances and containers in larger virtual machines (VMs). Now you can pool core counts to better fit SQL Server license editions to your business needs. With our logical consolidation, you have fewer operating systems to manage and better dependency coordination.

Dramatically reduce SQL Server licensing costs and improve agility

You choose whichever SQL Server edition and OS version meets your business requirements. Most of our customers find that with DxEnterprise, they can use SQL Server Standard edition for 80% of their datacenter needs—without needing Software Assurance for mobility—for dramatically reduced SQL Server licensing costs. All with full SQL Server license compliance and without ecosystem lock-in. You get vastly simplified high availability and disaster recovery, with DR playbook automation and alerting.

  • Stack instances in large VMs with pooled core counts to match licenses to actual need
  • Use SQL Server Enterprise edition only when its features are needed, not just for HA/DR
  • Pay for the licenses you need as you need them and expand your VM size
  • Manage fewer OSes overall, with easy OS isolation where necessary
  • Dramatically improve datacenter orchestration with better agility and reduced complexity
  • Meet future needs cost-effectively and with greater flexibility
  • Patch non-active nodes to solve patch/update/refresh problem
  • Consolidate to superior license utilization not possible without DxEnterprise
  • No ecosystem lock in
  • Applications no longer have to be offline for a server to boot
Liberate your datacenter—no matter how it’s deployed
