GreyBeards talk VMware agentless backup with Chris Wahl, Tech Evangelist, Rubrik

In this edition we discuss Rubrik’s converged data backup with Chris Wahl (@ChrisWahl), Tech Evangelist for Rubrik.  You may recall Chris as a blogger on a number of Tech, Virtualization and Storage Field Days (VFD2, TFD extra at VMworld2014, SFD4, etc.) which is where  I met him. Chris is one of the bloggers that complains about me pounding on my laptop keyboard so loud at SFDs ;/

Chris had only been with Rubrik about 3 weeks when we  talked with him but both Howard and I thought it was time to find out what Rubrik was up to.

Rubrik provides an agentless, scale-out backup appliance for VMware vSphere clusters. It uses VADP to tap into VM data stores and obtain changed blocks for backup data. Rubrik deduplicates and compresses VM backup data and customers define a SLA  policy at the VM, folder or vSphere cluster level to determine when to backup VMs.

Rubrik supports cloud storage (any S3 or SWIFT provider) for long term archive storage of VM backups. With Rubrik, customers can search the backup catalog (for standard VM, NFS file, and backup metadata) that spans the Rubrik cluster data as well as S3/SWIFT storage backups.  Moreover, Rubrik can generate compliance reports to indicate how well your Rubrik-vSphere backup environment has met requested backup SLAs, over time.

Aside from the standard recovery facilities, Rubrik offers some interesting recovery options such as “instant restore” which pauses a VM and reconfigures its storage to come up on the Rubrik cluster (as a set of NFS VMDKs). Another option is “instant mount”, which runs a completely separate copy of a VM using Rubrik storage as its primary storage. In this case the VM’s NIC is disconnected so that the VM gets an error when it fires up, which has to be resolved to run the VM.

Rubrik hardware comes in a 2U package with 4 nodes. Each node has one flash SSD and 3 4 or 8TB SATA disks for customer data. The SSD is used for ingest caching and metadata. Data is triple mirrored across SATA disks in different nodes.

The latest release of Rubrik supports (compressed/deduped) data replication to other Rubrik clusters located up to asynchronous distances away.

This months edition runs just under 42 minutes and gets somewhat technical in places. We had fun with Chris on our call and hope you enjoy the podcast.

GreyBeards discuss server side flash with Satyam Vaghani, Co-Founder & CTO PernixData

Episode 2: Server Side Flash Software

Welcome to our second GreyBeards on Storage (GBoS) podcast. The podcast was recorded on October 29, 2013, when Howard and Ray talked with Satyam Vaghani, Co-Founder & CTO PernixData, a scale-out, server side flash caching solution provider

Well this month’s podcast runs about 40 minutes. Howard and I had an interesting and humorous discussion with Satyam Vaghani, who was a leading architect of VMware’s storage and file system stack and now is currently Co-Founder/CTO of PernixData, which offers a server side caching solution. Unlike other solutions in this space, Pernixdata offers advanced write-back caching and scale-out clustering solution for server side flash for data used by VMs running under vSphere. We discuss how they provide these features and why in our second podcast episode. Although why people are running analytics in a VM using server side flash is still a mystery …

 

Satyam Vaghani Bio’s

Satyam Vaghani, Co-founder and CTO Pernixdata
Satyam Vaghani is Co-Founder and CTO at PernixData, a company that leverages server flash to enable scale-out storage performance that is independent of capacity. Earlier, he was VMware’s Principal Engineer and Storage CTO where he spent 10 years delivering fundamental storage innovations in vSphere. He is most known for creating the Virtual Machine File System (VMFS) that set a storage standard for server virtualization. He has authored 50+ patents, led industry-wide changes in storage systems and standards via VAAI, and has been a regular speaker at VMworld and other industry and academic forums. Satyam received his Masters in CS from Stanford and Bachelors in CS from BITS Pilani.
