What Is KVM?

In a world of rapidly changing and evolving virtualization infrastructures, vendors are in constant pursuit of making them more robust, reliable, operational, and, to put it simply, overall more efficient. Kernel-based Virtual Machine (KVM) is an open-source virtualization technology that converts Linux into a bare-metal hypervisor, having all the necessary components (memory manager, process scheduler, input/output (I/O) stack, etc) as a part of Linux kernel. In comparison with the most industry-leading products, KVM hypervisor offers much more flexibility for its users, leaving a lot of free room for improvement, so that migrating to KVM-based virtual infrastructure seems like actually quite a reasonable idea. Since it is a part of large and broad Linux family, it is safe to say that everything that Linux can offer KVM can offer too.

Red Hat Linux KVM
and StarWind VSAN

StarWind VSAN is a useful addition to any environment since it runs as a native hypervisor component. Still, in the case with kernel-based virtual machine and KVM hypervisor specifically, their union can lead to impressive performance results:

  • As Linux KVM possesses traditional Linux performance, allowing the most demanding app loads to be virtualized, StarWind can provide highly available block storage to build HA Cluster using Linux KVM.
  • Live migration, supported by KVM hypervisor, guarantees a stable work of a VM even if relocated, and StarWind iSCSI can provide maximum bandwidth for block storage transfers, making VM migration look easy.
  • Linux KVM technology is flexible enough to utilize basically any storage supported by Linux, using multipath I/O to provide required redundancy; at the same time, StarWind VSAN manages storage to match VM workloads, so that storage performance is on top without requiring costly storage and simultaneously avoiding random I/O.
  • Linux KVM hypervisor is a force to be reckoned with by itself, but with StarWind VSAN, its key features can be developed to their full potential.

What Is
StarWind VSAN?

For small and medium-sized businesses or ROBO, such a small step in development as building an IT infrastructure can turn out to be a severe challenge. Unlike big enterprises, not everybody can afford expensive custom hardware. However, StarWind Virtual SAN seems to be a perfect fit for such cases because it allows creating a shared storage pool with off-the-shelves hardware at minimal costs, bringing to the table a rich feature-packed stack as well. Not only would it make your environment more efficient with a minimum of resources, StarWind, working on 2 nodes, can still keep your infrastructure high available and fault-tolerant, since it keeps functionality even if one of the nodes goes off due to failure or outage.

StarWind VSAN
Features and Benefits

A prime choice for small businesses, StarWind Virtual SAN, makes shared physical storage to seem obsolete. While enabling your environment with an outstanding performance, reliability, and fault-tolerance, this product fulfills a lot of functions with its broad feature specter. Easy in managing, configuring, and deployment, it provides you with several benefits.

Budget-Friendly

By limiting the hardware footprint accompanying traditional physical storage, StarWind VSAN allows you to double your savings by lowering CapEx and OpEx. You can forget about additional licensing expenses as well. Naturally, as any product of a kind, it still requires hardware for work, but the difference in price between custom hardware and commodity one is evident enough.

Performance and Features

Running on basically every hypervisor, StarWind Virtual SAN can offer simplicity in use and configuration that hardly can be matched. You don't need specific knowledge to operate it, every admin with a standard experience of working with virtualized environments can quite easily manage, configure, and deploy StarWind VSAN.

Simple in Use

StarWind Virtual SAN provides an impressive performance level. Apart from being hardware agnostic, guaranteeing fault-tolerance of the environment, and providing high availability for application, VSAN brings to the table a set of features specifically designed for this product, such as server-side cache, LSFS, Automated Storage Tiering, etc.
