When RamDisks Get Full

|2 Influencers

This is just the sort of cool technical tip that saves your bacon when it’s lodged somewhere in your mind: What happens when the VMware ESXi RAMdisk gets full? Here’s Tom Howarth’s account…

After upgrading to ESXi 5 we saw several instances of host instability as the Ramdisk ram out of space, symptoms including :-

An introduction to Storage DRS

|2 Influencers

I’m not sure that everyone would agree that Storage DRS is the most exciting new feature in vSphere 5, but it’s certainly in the top 10. Here’s Duncan Epping’s overview of Storage DRS and datastore clusters. Nice video too!

vSphere 5.0 introduces many great new features, but everyone will probably agree with us that vSphere Storage DRS is most the exciting new feature.

EMC denies big server biz plans … but IS building servers

He observed: “Server vendors put DAS (direct-attached storage) in servers. Storage vendors put compute in storage. Over time these hybrid configurations will get more workloads.”

Windows Server 2012 Hyper-V & Network Card (NIC) Teaming

|2 Influencers

A great little piece on NIC teaming with Windows. Aidan Finn says his mind is changed now that it’s included in Windows Server 2012 and fully supported for Hyper-V and failover clustering.

True, MSFT hasn’t had NIC teaming and there’s a KB article which says they don’t support it. NIC teaming is something that the likes of HP, Dell, Intel and Broadcom provided using their software. If you had a problem, MSFT might ask you to remove it. And guess what, just about every networking issue I’ve heard on on

The Stack Wars: OpenStack vs. CloudStack

|2 Influencers

Overall, CloudStack is better packaged for enterprise adoption, especially in environments not already familiar with open source. Its installation packaging and customizable admin/end-user portal are designed for quick, scalable adoption of the private cloud. OpenStack, on the other hand, can be best described as a foundation or framework for cloud computing, not nearly as polished.

Howard Marks and Robin Harris Debate SSD Array Architecture

|2 Influencers

As if it wasn’t obvious already that SSD is the most controversial topic in enterprise storage, here’s Howard Marks and Robin Harris with a great back-and-forth about array architecture. We can’t wait to read the continuing exchange!

Building storage arrays from SSDs is opportunistic, not strategic. It isn’t the future for high-end storage, but less-demanding mid-markets may not care.

Do SSDs have a future in the all-solid-state array market? They sure do. Could a vendor looking for performance at all costs eek a few more IOPS and a few fewer microseconds of latency from custom modules? Probably, but I wonder if it will turn out

Cisco FabricPath vs. Brocade VCS

|2 Influencers

Two solid pieces by Joel Knight bring up facts and features of Cisco FabricPath and Brocade VCS. It’s nice to see this information so concisely presented, from topology to pros and cons. Good work, Joel!

This announcement centered on a strategy for software-defined networking (SDN), and this was the focus of our discussion as well.
