3Par Acquisition: The Future For The Storage Industry

September 1, 2010

The ongoing battle for 3Par by HP & Dell tells us much more about the state of the IT Industry than just the desires of two companies to acquire some interesting storage tech. It signals an acceptance that storage is a key feature in the future direction of the IT industry – more important than networking and almost as important as the virtualisation platform itself.

Data ONTAP 8.0 — Part III

August 10, 2010

I’ve twice posted now on Data ONTAP 8.0 shortcomings and this evening I did a little more research with the IBM version of Netapp’s hardware, the N-Series products. Fortunately, IBM are slightly more generous and informative in their documentation than Netapp and this document (freely available online) provides more background information on the “DOT8″ transition process. So, I’ve tried to produce a more in-depth objective view of the steps to move to “DOT8″. Firstly the following diagram provides a clue as to how Data ONTAP has migrated to the current release.

The DroboElite is the most fully featured storage array in the Data Robotics range of devices. Regular readers will know I’ve posted frequently on these devices, from the first Drobo “Classic” to the DroboPro, both of which I own and have purchased myself. Data Robotics have kindly loaned me a DroboElite for this series of posts. As you will see, the top of the range model offers all the features the other models provide, plus the benefits of multi-user support.

Four Pillars — Service: Chargeback

May 31, 2010

In any system, resources are finite. There is always a limitation to what is available. However there’s also a truism that states if resources are free then they will be consumed at an infinite rate. So it is with storage. Someone has to pay for the storage resources that are placed on the floor. If customers are not charged in some way for their consumption of storage, then they will continue to consume resources ad infinitum. The solution is to implement chargeback or, to be more precise, billing.
