VSAN 6.2 Upgrade – Failed to realign objects

Good post by Cormac Hogan (thank you)

A number of customers have reported experiencing difficulty when attempting to upgrade the on-disk format on VSAN 6.2. The upgrade to vSphere 6.0u2 goes absolutely fine; it is only when they try to upgrade the on-disk format, to use new features such as Software Checksum, and Deduplication and Compression, that they encounter this error.

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.”

NVMe fabric flash and deduping VSAN lead

The Future Road Sign with dramatic clouds and sky.

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

EMC has new storage products coming in both external shared array form and in its converged and hyper-converged systems lines of products, using new VSAN capabilities.

These will be announced over the next two quarters and will change the shape of EMC’s product lines. We think we now have an overall view of what the mainstream product lines will look like.

This information comes from EMC’s latest quarterly results earnings call, from various sources, and from blogs by EMC VCE president Chad Sakac.

The background includes the point that VMware’s VSAN/EVO:RAIL/EMC VSPEX Blue products have not apparently been successful, hence the need for a revamp of the core VSAN software.

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.
