VMware Virtual SAN: Performance with Microsoft Exchange Server

Post by Rawlinson Rivera (thank you)

As we continue to showcase the value and capabilities of Virtual SAN, I believe it is crucial to provide access to the information VMware’s performance engineering team has gathered around business critical applications and their respective performance benchmarks.

This white paper focuses on Microsoft Exchange Server performance on VMware Virtual SAN. Microsoft Exchange Server is a commonly found email server and is considered a business-critical application by many organizations.

The promise of next-generation WAN optimization

Good post by Enrico Signoretti (thank you)

Bandwidth, throughput, and latency aren’t issues when you are within the boundaries of a data center, but things drastically change when you have to move data over a distance. Applications are designed to process data and provide results as fast as possible, because users and business processes now require instant access to resources of all kinds. This is not easy to accomplish when data is physically far from where it is needed.

The future of tape looks bright with the promise of 120TB of storage on a single LTO tape

Post by Laura Loredo (thank you)

Why is today a great day for tape users in general and LTO technology in particular? Because the LTO Program announced the extension of the technology roadmap to 10 generations. This increases capacity expectations to 120 TB per cartridge.

The roadmap has always been one of the key foundations of the success of the LTO Technology, which now has an installed base of 4.7 million LTO tape drives and over 250 million LTO cartridges.

Why Have VVOLs Taken So Long to Deliver?

Post by Chris M Evans (thank you)

Another VMworld has come and gone and still we haven’t seen the production deployment of VVOLs.  Just to recap, VVOLs are the evolution of the packaging of virtual machines that currently reside in data stores.  The main benefit is to be able to apply storage performance and availability policies to a VM object rather than an entire datastore as we do today. Although we’ve seen demonstrations of VVOLs for some time, VVOL code has not yet made it into a GA vSphere launch.  Presumably this will change with the release of vSphere 6.0 sometime next year.

You know what Cisco needs? A server SAN strategy

Post by Chris Mellor (thank you) over at El Reg

Cisco has no SAN/filer legacy to escape from and, in a storage world where the hyper-converged server/storage/networking system is only getting trendier, it has a major opportunity on its hands.

Consider the mainstream storage vendors – Dell, EMC, Fujitsu, HDS, HP, IBM and NetApp – their storage product line heartland is the shared, networked array.

Is the all-flash data centre just a tantalising dream?

Post by Chris Mellor (thank you) over at El Reg

An all-flash data centre? It’s an intriguing idea. The hardware and software components may be there, but what about the business case, including the overall price/performance and total cost of ownership?

Yes, such a data centre will be free of power-gobbling and rack space-consuming spinning disk enclosures, bringing consequent savings in cooling, but storing data bits in NAND costs more than writing them onto disk-platter recording media.

Can your Backup Design handle Veeam?

Post by George Crump (thank you)

Veeam and data protection applications like it, arm data protection professionals with a new set of capabilities that they didn’t have access to in the past. So powerful are these capabilities that they can justify the acceleration to a 100% virtualized infrastructure. But these new features place new demands on the data protection infrastructure and IT Planners need to re-think their backup architectures.

SimpliVity Puts the S in Cisco UCS; Announces New Relationship

Post by Eric Wright (thank you)

This is a big day for the team at SimpliVity as they announce a new relationship with Cisco to provide the SimpliVity PCIe Accelerator Card and OmniStack feature set on Cisco UCS C240 M3 Series Rackmount server platform.

This is definitely a powerful move for SimpliVity to extend the reach of their flagship OmniStack sotware platform for hyperconverged management. Cisco will be winning in the relationship also due to the feature set that OmniStack can now provide to their customers on the UCS C240 hardware.

All-Flash Arrays vs. Performance Management

Post by George Crump (thank you)

Optimizing storage performance is almost an art. One of the earliest papers I wrote for Storage Switzerland was “Visualizing SSD Readiness“, which articulated how to determine if your application could benefit from implementing  solid state disk (SSD). It also discussed how to determine which files of your application should be put on the SSD. Remember that in 2009 no one could imagine putting an entire application on SSD, let alone an entire data center! Now though, thanks to all-flash arrays, we can. But does that mean we can abandon performance management as a discipline?

Cisco UCS Invicta off the shelves, for now

Post by Richard Chirgwin (thank you) over at El Reg

Reports are emerging that Cisco is holding back its UCS Invicta storage products because of unspecified performance issues.
