Hot Trendy Topic : NetApp Technology in The IT CityNow everything can be done using two servers connected directly via 10G-connection:
This requires not only less switches and servers, but also less than 10G adapters on Hyper-V host servers (4 pieces instead of eight). It is important that all the I/O requests go directly to the DAS Store Server, without requiring them to transfer over the network, which significantly increases the performance.
If this count, we can provide cost savings of up to 50% compared with all the other solutions, which provide fault tolerance at the level of storage and virtual machines:We now turn to the functionality of the product. StarWind Native SAN for Microsoft Hyper-V is a fully symmetrical active-active storage cluster of virtual machines in which there is simultaneous recording to both disk storage (combined into one logical) with full synchronization between nodes is (synchronized only changed blocks). If one of the Hyper-V nodes continues continuous operation without stopping the second I/O request virtual machines.
One of the features of StarWind Native SAN for Microsoft Hyper-V is a built-in reduplication, a mechanism that allows you to record only the unique blocks on disk drives, resulting in space savings of 20-30% for many environments. All this takes place in-line, i.e. while recording data to the disk.
Additionally, StarWind SAN uses a disk caching technology blocks in the main memory, which significantly increases the performance of the solution in terms of high performance I/O and low latency. Well, the important point, you can adjust the block size to optimize storage for different types of application workloads.
The following function StarWind Native SAN for Microsoft Hyper-V is the ability to use storage that grows as its data content (Thin Provisioning).
All this allows us to save money on the purchase of storage and its flexibility to scale as needed disk space.
Well, another interesting feature of StarWind Native SAN for Microsoft Hyper-V is the possibility of organizing an asynchronous storage replication to a remote site on the WAN connection in order to create a disaster recovery solution for virtualization.
All this will allow you to create a Disaster Recovery is a plan to restore the services running in virtual machines.
We also note a number of useful functions StarWind Native SAN for Microsoft Hyper-V:
- The ability to use snapshots (Snapshots) and clones at the level of storage
- Monitoring the performance of the cluster nodes
- Using different types of cache (write-back and white-through)
- Standards support the IPSec , the CHAP , the MPIO
- Support for Microsoft Windows Server Core
