I’m happy to announce that ZERTO www.zerto.com is a official sponsor of my blog.
About ZERTO
Business Continuity / Disaster Recovery in a virtualized environment is difficult – because virtual-ready replication methods are difficult to scale to large data centers. Traditional storage-based replication tools are complex, while virtual replication tools are not built for scale and reliability. With hypervisor-based replication, that changes. Zerto Virtual Replication is storage agnostic, simple to install and intuitive to use and is also compatible with vCloud.
There are two key components of the Zerto architecture:
Zerto Virtual Manager (ZVM) – The ZVM plugs directly into the virtual management console (such as VMware’s VCenter), enabling visibility into the entire infrastructure. The ZVM is the “brain” of the solution, managing replication for the entire VSphere domain, keeping track of applications and information in motion in real time.
Virtual Replication Appliance (VRA) – The VRA is a software module that is automatically deployed on the physical hosts. The VRA continuously replicates data from user-selected virtual machines, compressing and sending that data to the remote site over WAN links.
Because it is installed directly inside the virtual infrastructure (as opposed to on individual machines), the VRA is able to tap into a virtual machine’s IO stream. Therefore, each time the virtual machine writes to its virtual disks, the write command is captured, cloned, and sent to the recovery site. Unlike some replication technologies that primarily offer data protection along with cumbersome snapshots and backup paradigms, Zerto’s solution provides continuous replication with zero impact on application performance.
