I’ve got a lot to say about storage, as you might have noticed from reading my blog. So I finally sat down and wrote a book on enterprise storage. Now you can download the e-book for free, thanks to support from my friends at SolarWinds!
I’ve talked a lot about the I/O blender in the last decade or so.[1. I’ve even been told I invented the term!] I’ve always said that information is the solution, allowing arrays to de-multiplex data. But a new enterprise storage company, Infinidat, claims that they can beat the I/O blender using math. Here’s their concept.
Waves of innovation and waves of companies, crash on the storage market, but the same incumbent leaders and product lines survive for decades. Are things changing? It’s hard to see sometimes, but real progress has been made.
People call on storage devices and systems to do lots of things, from accelerating I/O to copying and sharing data. But at the heart of it all, storage arrays really have just one job: Do not lose data!
The time has come to take sides on the core question of storage for virtual servers: Do you want storage intelligence to live in the hypervisor or the array? Most administrators are already lining up on one side or the other, unintentionally casting their vote while the rest flounder. But the storage industry must wake up and embrace the divide.
Thin provisioning doesn’t take on the cost of capacity, it actually attacks the overhead of inefficient provisioning. Not all of that overhead is inefficiency, and not all of that can be tackled with thin provisioning. But some of it can. It’s a lot more of the cost than can be tackled by moving to SATA, for example. That I really like.
Why do we care about thin provisioning? Because storage is not getting cheaper. If you went to buy a disk ten years ago, you’re going to spend about the same as would today, but you’re going to get a lot more capacity – a lot more capacity! The fact that we have terrible utilization of enterprise resources is really not helping us, and it’s not getting any better. It hasn’t improved because they are “doing storage” the same way.
