Why it is Incorrect to use Average Block Size for Storage Performance Benchmarking

Just a quick post to address something many people either get wrong or just live with due to convenience.

In summary: Please, let’s stop using average I/O sizes to characterize storage system performance. It’s wrong and doesn’t describe how the real world works. Using an average number is as bad as using small block 100% read numbers shown in vanity benchmarks. Neither is representative of real life.

Using a single I/O size for benchmarking became a practice for a vanity benchmark and to provide a level playing field to compare multiple products.

But, ultimately, even though the goal of comparing different systems is desirable, using a single I/O size is fundamentally flawed.

Status and the Nimble acquisition by HPE

Just a quick post since I’m getting inquiries regarding the status of my vital signs.

Yes, I’m alive, just very busy helping with the ongoing integration of Nimble Storage into HPE and all kinds of cool AI.

All kinds of training to be done all around, positioning guides to be written, strategy to plan, technology to design.

How Nimble Customers Benefit from Big Data Predictive Analytics

In past articles I have covered topics about how Nimble Storage lowers customer risk with technologies internal to the array such as:

Now, it’s time to write a more in-depth article about the immense customer benefits of InfoSight, Nimble’s Predictive Analytics platform.

Nimble Cloud Volumes Removing Risk From Cloud Storage

As of February 27th 2017, Nimble Storage announced Nimble Cloud Volumes (NCV), marking Nimble’s entry into the cloud space.

For those short on time: Nimble Cloud Volumes is block storage as a service, works with compute from AWS & Azure, and avoids the significant block storage drawbacks of those two providers. In essence, it is enterprise storage as a service, at a competitive price, while retaining all the cloud conveniences.

Practical Considerations for Implementing NVMe Storage

Before we begin, something needs to be clear: Although dual-ported NVMe drives are not yet cost effective, the architecture of Nimble Storage is NVMe-ready today. And always remember that in order to get good benefits from NVMe, one needs to implement it all the way from the client. Doing NVMe only at the array isn’t as effective.
