Tracking down noisy neighbors

Good post by Frank Denneman (thank you)

A big part of resource management is sizing of the virtual machines. Right-sizing the virtual machines allows IT teams to optimize the resource utilization of the virtual machines. Right sizing has become a tactical tool for enterprise IT-teams to ensure maximum workload performance and efficient use of the physical infrastructure. Another big part of resource management is keeping track of resource utilization, some of these processes are a part of the daily operation tasks performed by specialized monitoring teams or the administrators themselves. Service Providers usually cannot influence the right sizing element, therefor they focus more on the monitoring part.

Buying Guide: Backup Appliances

Post by Drew Robb (thank you)

IDC recently put out a report on the worldwide purpose-built backup appliance (PBBA) market. The big news was declining revenues, which are likely to continue due to changes in the dynamics of this space.

“The worldwide PBBA market experienced a year-over-year decline in the second quarter of 2015 as the market continues to evolve,” said Liz Conner, a storage analyst at IDC. “Focus continues to shift away from hardware-centric, on-premise PBBA systems to hybrid/gateway systems. The results are greater emphasis on backup and deduplication software, the ability to tier or push data to the cloud, and the increasing commoditization of hardware, all of which require market participants to adjust product portfolios accordingly.”

Is Software-Defined Storage Enough?

Good post by George Crump (thank you)

Initiatives like server virtualization, cloud infrastructure-as-a-service, and real-time analytics are allowing IT to meet today’s ever-increasing business demands. These initiatives are designed to bring agility to the data center, yet they trip and fall when they have to interact with the silo’ed storage infrastructure. Software Defined Storage (SDS) was supposed to be the answer. But for the most part, SDS is really storage software without the reliance on dedicated hardware, and is limited to specific storage containers. Most SDS solutions cannot extend a container across vendors, formats (file, block, object) or protocols. Even hyper-converged systems don’t help. They attempt to solve this problem by moving all enterprise data into a bigger and proprietary container at the server layer.

Virtual Volumes (VVols) and Replication/DR

Good post by Cormac Hogan (thank you)

There have been a number of queries around Virtual Volumes (VVols) and replication, especially since the release of KB article 2112039 which details all the interoperability aspects of VVols.

In Q1 of the KB, the question is asked “Which VMware Products are interoperable with Virtual Volumes (VVols)?” The response includes “VMware vSphere Replication 6.0.x”.

Google cloud offers SSD storage

Post by Ray Lucchesi (thank you)

Read an article the other day on Google Cloud tests out fast, high I/O SSD drives. I suppose it was only a matter of time before cloud services included SSDs in their I/O mix.

Yet, it doesn’t seem to me to be as simple as adding SSDs to the storage catalog. Enterprise storage vendors have had SSDs arguably since January of 2008 (see my EMC introduced SSDs to DMX dispatch). And although there are certainly a class of applications that can take advantage of SSD low latency/high IOPs, the vast majority of applications don’t seem to require these services.

Cloud storage is way better than storage on your own device

Good Post by Leo Leung (thank you)

Bold statement? I was a bit surprised at the conclusion myself. But, let’s take a deeper look.

I’ve obviously made certain choices regarding storage, and have done my own comparisons at certain points in time, but was prompted to update my thoughts after a recent tweet by Chris Mims of the WSJ:

The Next Generation Data Center is a Model all Enterprises can use

Post by Eric Slack (thank you)

It’s true that the concept of the Next Generation Data Center (NGDC) was born in the cloud provider space as a way to describe the infrastructure  these companies need to meet their often extreme resource requirements. Cloud providers have to satisfy the appetites for storage, compute and networking that their customers develop, and do so for all of them, simultaneously. And they have to do it often with little advance notice, while under some unforgiving service level agreements – and still turn a profit. Interestingly, these are the same kinds of demands being placed on the traditional “mainstream” environments.

The Problems With Server-Side Storage, Like VSAN

Good post by Colm Keegan (thank you)

The expression, “everything old is new again”, certainly applies to the renewed interest in server-side storage. Due to the widespread adoption of server virtualization technology, internal server storage is once again being hailed as a simple way to bring performance closer to where virtualized applications reside – on the hypervisor.

Now with VMware’s recent launch of their VSAN offering, which utilizes server-side storage capacity configured across a network of clustered hypervisor nodes, this seems to add further validation to this methodology. While there are some instances where server-side storage adds value, there are also some drawbacks that need to be considered.

Don’t Let File Sync and Share Sink Your Business

Good post by Colm Keegan (thank you)

Data “leakage” is becoming an increasing problem for businesses today given the widespread use of consumer grade file sync and share services. To maximize their productivity, many users will sync their file data across their laptop, tablet, smartphone and home desktop computers using these cloud file sync and share applications.

IT organizations have neither insight nor control over any of this information. In addition, many of these services don’t employ stringent security access protocols; users simply provide login credentials to gain access to their accounts. This can potentially result in sensitive business data being exposed to unauthorized users or compromised by hackers.

Is tiered storage obsolete? Yes and no!

Post by John Martin (thank you)

Traditionally, discussions about enterprise storage economics revolved around the concept of a multi-tiered model. In reality, this often had more to do with vendor portfolio economics than customer requirements. But the emergence of flash has changed this forever.
