StarWind Native SAN - 1/2 of classic SAN cost

You can assure yourself that StarWind Native SAN for Hyper-V saves at least 1/2 of your budget reserved for the hardware:

Classic SANStarWind Native SAN
Hardware Server (Xeon 5620, 8GB RDIMM, PowerSupply 450W, etc)4 x $2000 = $80002 x$ 2000 = $4000
UPS (APC Power Saving Back-UPS Pro 1500)4 x $250 = $10002 x $250 = $500
RAID array (with support of RAID10)4 x $600 = $24002 x $600 = $1200
6 disks (2 x 146GB - system 4 x 0.5TB - Data)$4200(2 x 200$) + (4 x 350$) = $2100
SoftwareOS2 x $4000 (Windows Server 2008 R2 Enterprise ) + 2 x $1100 (Windows Server 2008 R2Standart) = $102002 x $4000 (Windows Server 2008 R2 Enterprise) = $8000
SAN Software$3500 (average price)$3850 (One StarWind license)
Operational ExpendituresIT labor (annual)$15600 x 20% = $3120$7800 x 20% = $1560
Network Expenses10 GbE NIC (Intel X520-T2)8 x $750 = $60004 x $750 = $3000

*Formula For server: S = T x P x C = 8760hours x 0,65kW/hour x $0,112; For switch: Sw = T x P x C = 8760hours x 0,05kW/hour x $0,112 = $49.056
**for Classic SAN solution: E = 4 x S + 2 x Sw
***for Native SAN solution = 2 x S

StarWind Native SAN works on your existing Hyper-V servers


StarWind requires only two already existing Hyper-V servers to run in a full high available cluster at the time other hardware and software SAN solutions require at least four physical nodes to have the same configuration built to provide the same level of fault tolerance and redundancy. This all happens because StarWind is native Windows application and can co-exist with Hyper-V on the same physical server just fine. Something neither fully hardware SANs nor *NIX based software SANs can do. As a result StarWind needs 1/2 of expected hardware (servers and network infrastructure: switches, network cards, cabling and so on). ROI is huge.

StarWind requires less disk space

StarWind wisely uses disk space because of built-in de-duplication technology. Virtual machine images stored on a SAN volume have a typical overlap coefficient between 20x and 30x. This means in a nutshell: more virtual machines you have – more copies of the exactly same data you store on the disk. StarWind finds duplicated blocks and keeps only one copy of it with a multiple references on it. As a result quite common 2 TB of disk space residing on an ordinary Hyper-V server could be used to hold 40-60 TB of virtual machine images. The same applies to server's main memory, that StarWind uses as a level one cache to accelerate disk I/O and decrease access latency and response time. Already de-duplicated blocks stored in RAM provide effective multiplication of RAM and cache level one size. Pretty typical 2 GB of RAM allocated for cache turn to work as an enormous 40 – 60 GB because they hold data as one instance of block and reference count on it.

StarWind works fast on slow WAN connection

StarWind has built-in asynchronous replication allowing having "last resort" disaster recovery site with a mirror copy of the SAN volume located somewhere miles away from the main data center. What makes StarWind WAN acceleration technology unique is a heavy use of a de-duplication combined with a set of know-how's. Classic WAN accelerators rely on compression technology entirely thus they are limited to a very typical 2x - 3x compression ratios.

StarWind combines its snapshot technology, fast and effective compression and a variable block de-duplication resulting 50x – 100x transmitted data reduction coefficients. As a result slow WAN connection could be used nearly as a fast LAN link for bi-directional transfers.

Tangible CapEx and OpEx cost savings

StarWind storage solutions provide immediate, tangible and quantifiable cost savings from your virtualization infrastructure. With new StarWind Native SAN for Hyper-V, you can reduce capital and operational expenses, while minimizing any potential lost revenue associated with downtime, outages and failures.

Reduce Capital and Operational Expenses with StarWind Native SAN for Hyper-V:
  • Reduce CapEx through consolidation
  • Reduce OpEx through automation and better management
  • Minimize lost revenue due to zero downtime

StarWind Native SAN for Hyper-V solution helps reduce your physical infrastructure footprint by consolidating excess server hardware and increasing server utilization:
  • Increase utilization rates of existing hardware from 5-15% to up to 80%
  • Defer datacenter construction costs by $1000/ sq ft *
  • Achieve 20-30% lower cost-per-application
  • Reduce annual IT labor costs by more than 50%
  • Reduce hardware requirements by a 10:1 ratio or better

Lower Maintenance Costs

Value of Zero Downtime Server Maintenance is required for:
  • Updates to component hardware
  • Updates / patches to the hypervisor
  • Migration to newer servers
Cost savings from zero downtime server maintenance with StarWind Native SAN for Hyper-V:
  • Avoid overtime cost to perform maintenance
  • Avoid administrative time in scheduling downtime
Business costs of downtime is specific to each industry and not included here.
