This is post 7 of 9 in the series “NexGen Storage ioControl Tech Talks” In previous posts I’ve discussed the need to “move up the stack” with reference to the way we manage data. To recap, what we mean here is focusing less on the bits and bytes of how data is stored and moving […]
This is post 4 of 9 in the series “NexGen Storage ioControl Tech Talks” In my previous post I discussed the evolution of hardware management using the seasoned analogy of pets and cattle. It’s worth taking a step back and looking at what data we are creating and why, as this gives us insight into […]
This is post 1 of 9 in the series “NexGen Storage ioControl Tech Talks” Since the financial crash of 2008, the predominant IT mantra has been to do “more with less” – perhaps it was said well before that too, because IT (and in particular storage) is on a growth curve that isn’t likely to […]
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 â€“ more important than networking and almost as important as the virtualisation platform itself.
Iâ€™ve twice posted now on Data ONTAP 8.0 shortcomings and this evening I did a little more research with the IBM version of Netappâ€™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 â€œDOT8â€³ transition process. So, Iâ€™ve tried to produce a more in-depth objective view of the steps to move to â€œDOT8â€³. Firstly the following diagram provides a clue as to how Data ONTAP has migrated to the current release.
In the previous article I discussed the subject of Billing and Chargeback. This entry discusses some of the issues raised in that post as additional considerations.
The DroboElite is the most fully featured storage array in the Data Robotics range of devices. Regular readers will know Iâ€™ve posted frequently on these devices, from the first Drobo â€œClassicâ€ 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.
In any system, resources are finite. There is always a limitation to what is available. However thereâ€™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.
Iâ€™m not a fan of making press releases on behalf of other companies however once in a while, a news item catches my interest. So it is with the announcement of the Violin Memory Inc. 3200 series of all-memory storage arrays. Why are these interesting? Because I think they are moving and potentially blurring the boundaries between spinning drives and memory-based permanent data storage.
As discussed previously, the Service Catalogue is a key component of delivering storage as a service. In this post, Iâ€™ll explore some thoughts on developing a Service Catalogue and how its abstraction from technology allows the delivery of a more efficient operation.
