Two weeks ago Vilolin Memeory and Symantece announced a collaboration  to deliver flash-optimized data management capabilities. Since virtually everybody in the IT industry is at VMworld, that provided the opportunity for Narayan Venkat from Violin and Ashish Yajnik from Symantec to sit down for a brief chat.

I spend a lot of time with customers discussing the value of using Storage Foundation. A question I get asked a lot these days is "Brian that all sounds great, but what do I need to do to install it on existing systems". This is a very good question particularly since Storage Foundation is perfect to facilitate not only server platform migrations but storage migrations also. Customers can quickly see the advantages of a solution like Storage Foundation but what are the practicalities of retrofitting it? High level there are two forms of migrations. Offline migration where filesystems are offline during the conversion process and Online. Online migrations still incur an outage at the first stage (an umount and remount of filesystems) but the conversion is done while the filesystems are mounted.  To help pull this information together I have written a short document that outlines the offline version for all the Operating Systems. There are also links to the documents...

Virtualization is everywhere, but IT organizations are still looking for ways to cut costs.  One way to do that, is to…  virtualize even more applications!  However, the easy stuff has been done.  File and print servers, cafeteria menus and the company picnic blog have been virtualized.  The next step is to move up the chain and virtualize business and mission critical applications.  But the risks of virtualization are still there.  How do I monitor and protect my application and business services in the event of a failure, or even a site wide disaster?  What happens to the performance or availability of my data when a path connecting a virtual machine to the storage fails?  These are the roadblocks that are preventing IT organizations from virtualizing more of their business critical services and applications.  The good news is Symantec can help!

The Violin Memory and Symantec partnership announcement this week brings together the speed of Violin Memory's Flash Array and the IP of Storage Foundation for a purpose-built, super fast, super scalable solid state software stack. 

What does this mean for you? Storage optimization at the speed of memory:

  • Snapshot mangement: high scalable and highly performant snapshot technolgy at controller level for tier 1 applications, database acceleration, virtualization intiatives as well as virtual desktop infrastructures
  • Thin provisioning capabilities: Over-allocation of storage with ease of provisioning
  • Built-in deduplication: Deduplication ratio of up to 80% for reducing storage footprint
  • Replication: Incremental replication for complete disaster recovery 

Read some of the analyst coverage:

Diskgroup Name: DG1
Volume name: VOL
 
#[root@cluster-pri ~]# vxdg destroy DG1
#VxVM vxdg ERROR V-5-1-584 Disk group DG1: Some volumes in the disk group are in use
 
First check if volume is mounted

I have been working for Symantec for more years than I care to remember. I joined through the Veritas acquisition some 6 years ago. In that time the datacenter has changed incredibly, before joining Veritas I was a systems administrator, this was long before the concept of SANs were mainstream and most UNIX systems simply had direct attached storage. I think it’s fair to say that at some point over the past 10 years the datacenter began transitioning from physical to virtual and we at Symantec were very guilty of not adapting our solutions quickly enough. We went on selling our traditional clustering and storage management tools which while they have always been best of breed weren’t necessarily a good fit in virtual environments. Thankfully due to the strength of our portfolio our product team began to reinvest into adapting our solutions specifically into the virtual space. The upshot is now although there is still much development and innovation under way we have a...

Storage Tiering is a fairly well known concept in IT. Like many of these technologies It can often take many years before these cool concepts make it into the mainstream. Thin provisioning is a good example of this. I remember meeting 3PAR and them going over the technology with me. Here we are 5 years later and whilst thin provisioning is now very mainstream, customers implementations vary massively from Netapps check box implementation to many customers not wanting to over provision for fear of running out of storage at all. Storage Tiering is very simply the ability to move data about between different tiers of storage presented to the same host. Hardware vendors provide this in some high end arrays where it does of course come at a high cost and you can only tier within an enclosure. Over time these technologies have improved, for a long time arrays could only tier at a lun level, meaning you had to move everything on a given lun to another higher/lower tiered lun. Technologies...
