Microsoft recently showcased the power of its private cloud in a TechEd event in North America, by building one onsite and running Hands on Lab on it. It included hardware mostly from Microsoft’s partner HP, and Microsoft Software stack. The video for the same is available here.
To get a better understanding of this private cloud (in terms of cost), we did a simple cost analysis of hardware infrastructure used for developing such a datacenter. This includes a simple blade system based datacenter, capable of serving around 1500 client systems. The datacenter hosts a huge number of virtual machines (VMs) which are in fact the pre-configured environment for Hands on Lab (HOL) for learning different technologies. These HOLs can be accessed by each of the client systems as and when required. Upon request, a copy of the VM is sent to the client machine, which becomes the personal copy for that client, but still running on the powerful servers of the Datacenter only. No actual processing is done at client's end, except for simple Internet Explorer based application sending and receiving the request to and from the datacenter.
Following are the rough figures explaining the hardware infrastructure along with cost estimate of the private cloud.
Sample Private Cloud Datacenter configuration and cost:
Blade Enclosure Unit
HP BladeSystem c7000 Enclosure with Flex-Fabric
HP BladeSystemOnboard Administrator
-Flex Fabric Management
-HP Integrated Lights-Out (ILO)
HP Proliant BL460c G7 Server Blade (model considered : HP BL460c G7 L5640 1P Svr (603256-B21)
-16 Server blades
-2P * 6 cores
-128 GB RAM
-2*146 GB HDD
-BL460c G7 - 128 GB RAM
$333,180 per blade * 16 = $5,330,880
HP IO Accelerator Card in each Blade (320 GB)
- Solid State Disk PCI Card
- 145,000 IOPS
- Read: 750 MB/s
- Write: 550 MB/s
-Sizes (GB): 640 or 320
$ 9,719 per Blade * 16 =
HP Storageworks 4400 EVA Fibre Channel SAN
- 4/8 Gbps Fibre Channel
-Dual Embedded SAN Switches
$13,839.20 including 8 HDDs
- 40 * 300 GB 15K RPM Disks
$1,491 * 40
HP FlexFabric Network
- Converged Infrastructure
-Virtual Connect Technology
-4/8 Gbps Fibre Channel
-1/10 Gbps Ethernet
Varies depending on infrastructure location and size
The total Infrastructure cost for this sample Private cloud datacenter turns out to be ~$5,585,161. The cost for software, installation, maintenance and upgrades would be further added to get the complete TCO for a private cloud.
This private cloud provides many benefits like scalability, self service capabilities, high customization, security, and reduced operational costs. So for the enterprises investing billions of dollars for their Infrastructure, this seems to be a reasonable price for all the benefits they gain, but for medium and small industries, this seems to be an investment into the unforeseen future.
