Data Retention for Dummies

Good post by Chris Mellor (thank you) over at El Reg

All is confusion. The old certainties are gone. New certainties just don’t exist. The shifting shapes, players, products and technologies in the storage landscape are seen through fog. How the heck does everything fit together?

After four days in Silicon Valley meeting startups the bewilderment ratio us even higher. It’s like Dragons’ Den, where each new player is shinier and brighter than the previous one, becomes your favourite but then, as sure as eggs are eggs, will be eclipsed by the next one.

How much Storage do i need ?

Good post in the Solarwinds forum (thank you)

When it comes to the enterprise technology stack, nothing has captured my heart &  imagination quite like enterprise storage systems.

Stephen Foskett once observed that all else is simply plumbing, and he’s right. Everything else in the stack exists merely to transport, secure, process, manipulate, organize, index or in some way serve & protect the bytes in your storage array.

But it’s complex to manage, especially in small/medium enterprises where the storage spend is rare and there are no do-overs. If you’re buying an array, you’ve got to get it right the first time, and that means you’ve got to figure out a way to forecast how much storage you actually need over time.

Why i think VSAN is so desruptive

Post by Chuck Hollis (thank you)

Looking for a great disruption story in enterprise IT tech?  I think what VSAN is doing to the established storage industry deserves to be a strong candidate.

I’ve seen disruptions — small and large — come and go.  If you’re into IT infrastructure, this is one worth watching.

A few years ago, I moved from EMC to VMware on the power of that prediction.  So far, it’s played out pretty much as I had hoped it would.  There’s now clearly a new dynamic in the ~$35B storage industry, and VMware’s Virtual SAN is very emblematic of the changes that are now afoot.

Understanding Software Defined Storage

Very good post by Pushpesh Sharma (thank you)

Storage systems are essential to the data center. Given the exponential rate of data growth, it is increasingly becoming more and more challenging to scale the enterprise storage infrastructure in a cost effective way.

Storage technology over the years has seen incremental technology advancements. The early days of enterprise storage were mainly direct-attached storage (DAS) with host bus adapters (HBAs)  and redundant array of independent disks (RAIDs.) The DAS advanced by more faster and more reliable protocols like ATA over Ethernet(ATA), serial attached technology adapters (SATA), external serial attached technology adapters (eSATA), small computer system interface (SCSI), serial attached SCSI (SAS), and fibre channel.

Re: The Rack Endgame: A New Storage Architecture For the Data Center

Post by Frank Dennemann (thank you)

Stephen recently post an excellent article about the future developments of enterprise storage architecture. His analysis about the different roles of storage is spot on, i.e. long-term capacity and short-term retention. Connecting high performance resources through high speed interconnects is an interesting idea, but I do have some comments I would like to share.

Is SolidFire the Symmetrix of the Cloud era?

Good Post by Enrico Signoretti (thank you)

EMC Symmetrix was introduced in 1990 (as a Mainframe storage) and it has quickly become one of the most successful enterprise Tier1 storage ever (Now the VMAX). It’s big (now supporting up to 3200 disks and 2048GB of cache) but its architecture is outdated and so are its features. What was good enough to sustain Mainframe and large Unix server workloads is no longer when having to manage thousands (or tens of thousands) of VMs.

Introducing the HP XP7 Storage – 7th generation of the XP Disk Array

Good Post by Clavin Zito (thank you)

oday I want to introduce you to the latest generation of the XP Disk Array, the XP7.  I want to tell you a bit of a personal story about my experience with the XP.  Back in 1997, I decided to leave HP Storage to take a job with another division of HP in Colorado Springs.

Continuous Cloud Infrastructure: Taking Storage Virtualization to the Next Dimension

Post by Hu Yoshida (thank you)

Continuous Cloud Infrastructure: Taking Storage Virtualization to the Next Dimension

Today, Hitachi Data Systems  announces the next step in storage virtualization, taking it to the next dimension to provide a continuous cloud infrastructure.

When Hitachi announced Virtual Storage Platform (VSP) with its modular architecture, we marketed it as 3D storage with the ability to scale up with the addition of cache modules and Intel processors, scale out with front and back end director boards, and scale deep through virtualization of external storage.

HP XP7 Storage Disk Array Announced

Post by Lyle Smith (thank you)

HP has announced XP7 Storage, an enterprise-class storage disk array that provides customers with lower total cost of ownership (TCO) for traditional storage workloads in mission-critical environments. HP XP7 Storage offers a combination of six 9s (i.e. 99.9999 percent) uptime, meaning less than 31.5 seconds of application downtime per year as well as always-on disaster recovery protection, increased system density and ultra-high, flash-driven performance.
