Server Consolidation Ratio


As a virtualization consultant I am always interested in performance figures of VMware implementations. Especially the achieved server consolidation ratio is an important figure in combination with the used hardware for the VMware implementation.

To get more inside this subject I would like to gather information on your VMware implementation and the achieved server consolidation ratio. I will publish this information on my Consolidation Chart  which is available for everybody. This way, you can compare your consolidation ratio to that of others!

When there is enough information I will publish the figures in a consolidation rate whitepaper.

I am asking the following information from you:

Number of hosts: provide the number of used hosts
Number of VM’s: provide the number of vm’s running
VMware version: ESX 3, ESX 3.5, ESX 4, ESXi 3, ESXi 3.5, ESXi 4
VMware HA: y/n (are you using VMware HA)
Tolerated host failures: (if you are  using VMware HA)
Used server brand: provide the used server brand
Used server type: provide the used server type
Number of CPU’s in host: provide the number of CPU´s per host
Type of CPU in host: provide the CPU type used
Number of RAM in host: provide the number of configured RAM
Used storage type: DAS, iSCSI, FC, NFS
Used storage: provide the brand and type of your storage
Satisfaction level: provide your satisfaction level of your VMware implementation in a rate of 1-5, 1=bad and 5=excellent
Remark: Any remark you would like to leave

You can provide your information as a comment to this post. I will process the comments to the consolidation chart.

I am looking forward to your information! The more information we gather the more value the consolidation chart has!

The Consolidation Chart is available here.

  3. Hey there,
    Cool post, I just found it and I am already a fan.

  6. Number of hosts: 4
    Number of VM’s: 74
    VMware version: ESX 4 U1
    VMware HA: y
    Tolerated host failures: disabled
    Used server brand: HP
    Used server type: 2x HP BL490G6 and 2x BL480G1
    Number of CPU’s in host: 2x Quad core with Hyperthreading in BL490G6 (total 16 CPUs per host) plus 2x QC in BL480G1
    Type of CPU in host: BL490G6 = X5570 (@ 2.9GHz), BL480G1 = E5430 (@ 2.6GHz)
    Number of RAM in host: 42GB in each BL480 and 72GB in each BL 490G6
    Used storage type: FC

    I just want to know what is the Consolation Ratio for the following two servers ( default workloads)

    1. IBM X3850 M2 (2 CPU – 4 Cores / CPU + 16 GB + 4 NICs).

    2. DELL PowerEdge 2950 (2 CPU – 4 Cores / CPU + 16 GB + 2 NICs).

    • Ted Steenvoorden says:

      Hi Khaled, sorry for the late reaction, i was quite busy. Looking at your server configuration the following consolidation ratio’s should be possible with vSphere (based on default workloads):

      1. IBM X3850 M2 (2 CPU – 4 Cores / CPU + 16 GB + 4 NICs): 7 vitual machines (based on Windows Server 2003).
      2. DELL PowerEdge 2950 (2 CPU – 4 Cores / CPU + 16 GB + 2 NICs): 7 vitual machines (based on Windows Server 2003).

      Adding more memory two both servers should increase the ratio. 32 GB for each server is certainly recommended based on the CPU configuration. Don’t forget your storage configuration!!

    Number of hosts: 7 (was 4, then 11)
    Number of VM’s: 51
    VMware version: ESX 3.5.5 (vSphere 4.1 ESXi Updt 2 in 2012)

    Used server brand: Dell
    Used server type: 3 R2950-III, 4 R900 –> 4 R910, 2 R900 v4.1-U2
    Number of CPU’s in host: 2
    Type of CPU in host: Intel, 5100, 5300, 7300 and R910 = E7 (10 core) x 2 per host
    Number of RAM in host: 2950-III (32GB) R900 (64G) R910 (128GB)
    Used storage type: EMC CX-500 FC –> VNX 5500/Nexus 5596
    Used storage: 27TB in total SAN (raw); of that, 65 drives 12.2TB for VMware LUNs.
    Satisfaction level: 110%

    • LarryT says:

      “Tolerated Host Failures” — we have never had a failed ESX host, but we have migrated all VMs (back in Perl SDK days) when we had to replace some of the original four Dell 2950 servers especially one that was a Lemon that Dell was kind enough to replace entire unit after replacing every internal board, etc for quote some time.

      • LarryT says:

        Note: all 2950 Class servers have 1 Dual HBA card to SAN ; and 6 1GBE Nics (1×2 port GBE on motherboard; 1 x 4 port GBE nic on PCI).

        Note: All Dell R900 and R910 have quad port GBE on motherboard and additional 4 port GBE on PCI. All R9xx servers have two dual-HBA FC cards to SAN; and we split LUNs so only R9xx servers see certain LUNs to meet and exceed IOPS that software vendor (mail archive) ever got on physical hardware.

        We extensively get massive IOPS and can’t wait to get the benefit of migrating from 2GB FC fabric to 8GB FC fabric when we upgrade SAN. We’ll think about certain amount of 1GB port consolidation as 2nd phase to migration. That’s why we will get Nexus 5596 so we can support entire FC fabric now and get 10GBE or 10GB FCOE, etc cards later
