Today, I helped our local Client Engineers install a couple of new nodes and some more storage into a local SONAS system. This was exciting for me as I love working with the hardware and software and it keeps up my keyboard skills. This client is bringing online more demand and needs both horsepower (interface nodes) and storage to accommodate a new business line. I was amazed at how easy the system is to upgrade and soon his little starter rack is almost full.
We added two interface nodes, IBM xSeries 3650 m2 and two 60 disk shelves to the unit. Once the disks are online and presented up to the interface modules, they can start creating shares for the new operation. As they need more storage or more interface nodes, another rack will be but in and the same process of pooling these resources together will come together.
The idea of having multiple interface nodes and storage pools is to not have single points of failure. In traditional storage, if a controller goes down, its partner has to pick up the entire work load for the down hardware. Not so in SONAS, if a controller goes down, the work is then evenly spread across all of the other nodes in the system. This is why we do not have a problem of loosing CIFS connections when systems go down.
The addition of new storage is also interesting as we are tripling the amount of storage the base system had originally with two 4 U shelves. These shelves are highly dense, top loading containers using either SAS or SATA disks. In this instance today, we were installing 120 2 TB SATA drives. A total of 240TB in 8 U of space. Not too shabby.
At the end of the day, I was pleased to see that IBM is moving forward with smarter storage systems. If you look at the entire portfolio, you can see that our systems like XiV grid, the auto tiering on DS8700, SVC virtualzation, all of these systems are helping our goal of a Smarter Planet. Look for some more pictures and maybe a video on Monday.
