How to handle the APD issue in vSphere

15 November 2013
Comments off
Reading Time: 4 minutes

In VMware ESXi the All Paths Down (APD) or Permanent Device Loss (PDL) condition is what occurs on an ESX/ESXi host when a storage device is removed in an uncontrolled manner from the host (or the device fails), and the VMkernel core storage stack does not know how long the loss of device access will last. A typical way of getting into APD would be a Fiber Channel switch failure or (in the case of an iSCSI array) a network connectivity issue. But there are also other scenarios that we will discuss later.

VMware vSphere cannot handle the case of a storage related failure (neither with VMware HA), so it’s really important to guarantee the redundancy of your storage and the usage of multi-pathing solution to build a resilient storage infrastructure according also with the best practices suggested by VMware and the storage vendor (see also this note).

One of the reason to wait before upgrade to VMware vSphere 5.5 was the lack of supported backup programs; except the one from VMware (vSphere Data Protection and the Advanced version).

During the recent VMworld Europe, I’ve got the opportunity to talk with Serge Shats, CTO FlashSoft a division of SanDisk about their storage cache product and their users cases in virtualization projects. I’ve already wrote a post about FlashSoft 3.2, and this was the opportunity to know the news about the new versions and the future plans.

By talking about SanDisk, most people think about the “consumer” market of the flash cards, where it’s well know. But SanDisk it’s not only flash cards, considering that they also product Solid State Devices (SSDs) for desktops, laptops, and ultrabooks. continue reading…

PoweringTheCloud2013
The second day of the Powering the Cloud event is almost similar to the first one (see the report of day 1), with the only main difference that it will finish some hours earlier. The entire show confirm the reasons to attend at this event, and I think to attend also the next year.

As written in the previous post, the agenda was almost dense and structured in different paths and topics, without specific general sessions.
