One of my longtime DataCore customers has started a project to replace their current DataCore storage servers and backend storage with new hardware. In opposite of the current setup, the newly installed backend storage is now FC-attached. The customer has selected Nexsan E-Series E32V, E32XV and E48V storage systems in combination with DataCore SANsymphony-V10.
Who is Nexsan? The question should be: Who is Imation? Nexsan was founded in 1999 in Derby, England, but was aquired by Imation in December 2012.
Since monday I’m helping a customer to put two HP 3PAR StoreServ 7200c into operation. Both StoreServs came factory-installed with 3PAR OS 3.2.1 MU3, which is available since July 2015. Usually, the first thing you do is to deploy the 3PAR Service Processor (SP). These days this is (in most cases) a Virtual Service Processor (VSP). The SP is used to initialize the storage system. Later, the SP reports to HP and it’s used for maintenance tasks like shutdown the StoreServ, install updates and patches.
Last sunday a customer suffered a power outage for a few hours. Unfortunately the DataCore Storage Server in the affected datacenter weren’t shutdown and therefore it crashed. After the power was back, the Storage Server was started and the recoveries for the mirrored virtual disks started. Hours later, three mirrored virtual disks were still running full recoveries and the recovery for each of them failed repeatedly.

PernixData is one of the presenting sponsors at the Virtualization Field Day 5 (VFD5). One of the four key announcements is FVP Freedom.
FVP Freedom will be available in the Fall of 2015 and it’s a completely free version of PernixData FVP. Of course, the functionality is limited. FVP Freedom will only support a single cluster, but with an unlimited number of VMs. Instead of SSDs, FVP Freedom will support up to 128 GB of DFTM (Distributed Fault Tolerant Memory) per cluster.
While I was playing with my shiny, new HP StoreOnce VSA in my lab, I noticed a curious behavior. I created a NAS share for some tests with Veeam Backup & Replication. Creating a new share is nothing fancy. You can create a share in two ways:
using the GUI, or using the CLI So I created a new share:

Nothing special, as you can see.
A free StoreOnce VSA, like the well known 1 TB StoreVirtual VSA? That would be too cool to be real. But it is real! Since February, HP offers a free 1 TB version of their StoreOnce VSA. I totally missed this announcement, but thanks to Calvin Zito I noticed it today:

Some days ago I talked to a colleague from our sales team and we discussed different solutions for a customer. I will spare you the details, but we discussed different solutions and we came across PernixData FVP, HP 3PAR Adaptive Optimization, HP 3PAR Adaptive Flash Cache and DataCore SANsymphony-V. And then the question of all questions came up: “What is the difference?”.
Simplify, then add Lightness Lets talk about tiering. To make it simple: Tiering moves a block from one tier to another, depending on how often a block is accessed in a specific time.
Some days ago a colleague and I implemented a small 3-node VMware vSphere Essentials Plus cluster with a HP 3PAR StoreServ 7200c. Costs are always a sore point in SMB environments, so it should not surprise that we used iSCSI in this design. I had some doubt about using iSCSI with a HP 3PAR StoreServ, mostly because of the performance and complexity. IMHO iSCSI is more complex to implement then Fibre Channel (FC).
Sometimes you have to update the OS of your DataCore Storage Server, or the server is crashed and you have to reinstall it. In both cases, a configuration backup is the starting point. The procedure remains the same, regardless if it’s an update or a reinstall after a server crash:
Install Windows Server OS Copy configuration backup file to C:\Program Files\DataCore\SANsymphony\Recovery Install DataCore SANsymphony-V Take a backup You can take the configuration backup on different ways:
On February 25, 2015 PernixData released the latest version of PernixData FVP. Even if it’s only a .5 release, FVP 2.5 adds some really cool features and improvements. New features are:
Distributed Fault Tolerant Memory-Z (DFTM-Z) Intelligent I/O profiling Role-based access control (RBAC), and Network acceleration for NFS datastores Distributed Fault Tolerant Memory-Z (DFTM-Z) FVP 2.0 introduced support for server side memory as an acceleration resources. With this it was possible to use server side memroy to accelerate VM I/O operations.
