A short note to let you know about some interesting news for Oracle/VMware customers. Oracle has just announced that it has licensed a number of VMware vSphere Storage APIs, including VMware vSphere API for Array Integration (VAAI), VMware vSphere API for Storage Awareness (VASA) and VMware vCenter Site Recovery Manager (SRM). As per the Oracle press release, “Support for these APIs will help simplify VMware customer access to the higher levels of performance and efficiency available with ZFS Storage Appliance and Pillar Axiom storage systems.” Read the full press release from Oracle here.
In my recent post about the new large 64TB VMDKs available in vSphere 5.5, I mentioned that one could not hot-extend a VMDK (i.e. grow the VMDK while the VM is powered on) to the new larger size due to some Guest OS partition formats not being able to handle this change on-the-fly. The question was whether hot-extend was possible if the VMDK was already 2TB or more in size. I didn’t know the answer, so I decided to try a few tests on my environment.
There is a new storage vendor on the block – COHO DATA – who just exited stealth and launched their new product with the tag ‘Storage for the Cloud Generation’. I had the opportunity recently to catch up with Andy Warfield, co-founder and CTO of COHO DATA. Andy has a long history of involvement with storage and virtualization. A graduate of Cambridge University in the UK, he was involved in XenSource where he developed much of the low-level storage integration mechanisms for external storage arrays like NetApp and DELL EqualLogic. Andy gave me an in-depth interview related to their new…
I met with the guys from Tintri at VMworld 2013 in San Francisco, and they had some nice new products that they were just on the verge of launching. Tintri has already made a number of announcements this year related to replication and availability in their VMstore system. The official new product announcement took place earlier this week (October 8th in fact), just in time for VMworld Europe, so I thought I’d highlight some of the them here.
Hmm, it seems to be the week that’s in it for storage issues. After publishing the DELL EQL & VMFS issue earlier this week, I have now been given a heads-up on an EMC VNXe & iSCSI issue. The symptoms are ESXi hosts being unable to boot from an iSCSI LUN on the VNXe or ESXi hosts losing connectivity to iSCSI datastores.
Our GSS folks just released KB article 2049103 which details a VMFS Heartbeat and Lock corruption issue that manifests itself on DELL EqualLogic storage arrays when running PS Series firmware v6.0.6. As per the KB: A VMFS datastore has a region designated for heartbeat types of operations to ensure that distributed access to the volume occurs safely. When files are being updated, the heartbeat region for those files is locked by the host until the update is complete. In this scenario, the heartbeat region has become corrupt.
As part of my storage vendors to check out at VMworld 2013 in San Francisco, one of the vendors I really wanted to catch up with was SanDisk and to learn more about their FlashSoft product. FlashSoft are run as the software division of SanDisk. In August 2012, they released version 3.0 of their I/O acceleration software, compatible with vSphere 5.0. In April 2013, they released version 3.1 which works with vSphere 5.0 & 5.1. I caught up with a number of folks from the FlashSoft team at VMworld 2013 to learn more about their product, and what their plans…
