Object storage: why, when, where… and but.

Good post by Enrico Signoretti (thank you)

In one of my latest posts I wrote about private object storage not being for everyone… especially if you don’t have the size that makes it viable… But, on the other hand we are all piling up boatloads of data and users need to access it from many different locations, applications and devices at anytime.

HP Announces A Series Of Innovations To Speed Flash Adoption In The Datacenter

Post by Adam Armstrong (thank you)

Today HP made a series of announcements around its 3PAR StoreServ Storage family. These announcements include lowering the price of flash capacity, new highly scalable all-flash arrays, and flash-optimized data services. These new innovations are aimed at accelerating the adoption off all flash in datacenters.

As we’ve seen over the past few years, flash technology is continuing to be adopted in many areas. With their increased density, performance, and predictability, all-flash arrays will continue to grow, in fact IDC forecasts that flash arrays will see a 46% compound annual growth rate over the next five years. Customers are looking to extend the benefits of flash into the datacenter.

vSphere Virtual Volumes Interoperability: VAAI APIs vs VVOLs

Good post by Rawlinson Rivera (thank you)

In 2011 VMware introduced block based VAAI APIs as part of vSphere 4.1 release. This APIs helped improving performance of VMFS by providing offload of some of the heavy operations to the storage array. In subsequent release, VMware added VAAI APIs for NAS, thin provisioning, and T10 command support for Block VAAI APIs.

Now with Virtual Volumes (VVOLs) VMware is introducing a new virtual machine management and integration framework that exposes virtual disks as the primary unit of data management for storage arrays. This new framework enables array-based operations at the virtual disk level that can be precisely aligned to application boundaries with the capability of providing a policy-based management approach per virtual machine.

The State of Deduplication in 2015

Good post by George Crump (thank you)

At its core, deduplication is an enabling technology. First, it enabled disk based backup devices to become the primary backup target in the data center. Now it promises to enable the all-flash data center by driving down the cost of flash storage. Just as deduplication became the table stake for backup appliances, it is now a required capability for flash and hybrid primary storage.

HP 3PAR, 360° storage

Good Post by Enrico Signoretti (thank you)

This is the first time in a while that I won’t be attending HP Discover. It’s a pity, not only because I have the chance to get updates directly from the horse’s mouth there, but also because it is always well frequented by good bloggers and other interesting people. At the event, HP usually organizes what they call “coffee talks” and you have the chance to get briefed and also have a lot of confrontation on each single line of their business (not that I’m really interested in everything they do, but Storage, Cloud and Enterprise IT in general are all well covered). BTW, thanks to my friend Calvin Zito I got news in advance and even though I’m overseas at the moment, I want to comment on what I discovered a few days ago.

The ultimate IOPS cheat sheet!

Good Post by Bas van Kaam (thank you)

Lately I’ve seen a lot of talk about IOPS, we need as many as possible and as such we are constantly on the look out for new ways to boost performance. No matter what kind of infrastructure we build, virtual or physical, or what ever products we use, in the end it all comes down to the end user experience. Topics often relate to flash like storage solutions, converged infrastructures, Citrix provisioning services, Machine Creation Services, or a combination of the above.

Designing Enterprise-class Multi-Tenant Storage

Post by George Crump (thank you)

Cloud Providers and enterprises must be able to guarantee performance to specific applications or groups of applications. They also need ways to distribute some of their storage management workload directly to the users or ‘interests’ they support. In the cloud provider use case this is typically divided up by subscriber. In the enterprise this may be divided up by line of business (finance) or by service type (Exchange group). In both cases the overall goal is to drive down the cost by making storage self-serviceable while assuring predictable application performance.
