The next step is to connect the Synology DS414slim to my lab network. I use two HP 1910 Switches in my lab, a 8 Port and a 24 Port model. The Synology DS414slim has two 1 GbE ports, which can configured in different ways. I wanted to use both ports actively, to I decided to create a bond.
Create a bond Browse to the admin website and go to Control Panel > Network > Network Interfaces and select “Create”.
This blog post covers the setup of the volumes and shares. Depending on your disk config, variuos volume configurations are possible. The DS414slim supports all important RAID levels (Synology Hybrid RAID, Basic, JBOD, RAID 0, 1, 5, 6 and 10). I recommend to use RAID 5, if you use more then two disks. I decided to create a RAID 5 with my three Crucial M550 SSDs and use the Seagate Momentus XT as a single disk.
Chris Wahl wrote a good blog post about the VAAI-NAS plugin some days ago. I really recommend to read this posting. Because of his article, I will only describe the installation of the plugin. You can download the plugin on the Synology homepage for free.
There are two ways to install the plugin: With the vSphere Update Manager (VUM) and a host extension baseline, or with ESXCLI.
Plugin installation using the vSphere Update Manager First of all, we need to import the plugin (host extension) to the patch repository.
HP has brushed up the StoreServ 7000 series and updated the StoreServ 7200 and 7400 models. HP also added a new model to the 7000 series: The StoreServ 7440c.
New 3PAR StoreServ models:

On October 28 2014 HP has published HP 3PAR OS 3.2.1 MU1, the first maintenance update for HP 3PAR OS 3.2.1. Beside some fixes, HP enabled in-line deduplication (Thin Deduplication) on all the systems with 3PAR GEN4 ASIC (StoreServ 7000 and 10000). Thin Deduplication does not require any license! It’s included in the base license and every customer can use it without spending money for it.
Thin Deduplication In-line deduplication is awesome, congrats to HP for making this possible.
Some days ago I wrote two blog posts (part I and part II) about VMware vSphere Metro Storage Cluster (vMSC) with HP 3PAR Peer Persistence. Because I wrote about it in the first of the two blog posts, allow me to take a short description, what Peer Persistence is and what it does, from that blog post:
HP 3PAR Peer Persistence adds functionalities to HP 3PAR Remote Copy software and HP 3PAR OS, that two 3PAR storage systems form a nearly continuous storage system.
The first part of this (short) blog series covered the basics of VMware vSphere Metro Storage Cluster (vMSC) with HP 3PAR Peer Persistence. This, the second, part will cover the basic tasks to configure Peer Persistence. Please note that this blog post relies on the features and supported configurations of 3PAR OS 3.1.3! This is essential to know, because 3.1.3 got some important enhancements in respect of 3PAR Remote Copy.
The title of this blog post mentions two terms that have to be explained. First, a VMware vSphere Metro Storage Cluster (or VMware vMSC) is a configuration of a VMware vSphere cluster, that is based on a a stretched storage cluster. Secondly, HP 3PAR Peer Persistence adds functionalities to HP 3PAR Remote Copy software and HP 3PAR OS, that two 3PAR storage systems form a nearly continuous storage system. HP 3PAR Peer Persistence allows you, to create a VMware vMSC configuration and to achieve a new quality of availability and reliability.
On the HP Discover in June 2013 (I wrote 2014, sorry for that typo). HP has announced the HP 3PAR StoreServ 7450 All-Flash Array. To optimize the StoreServ platform for all-flash workloads, HP made some changes to the hardware of the nodes. The 7450 uses 8-core Intel Xeon CPUs instead 6-core 1.8 Ghz CPUs, the cache was doubled from 64GB to 128GB and they added some changes to the 3PAR OS: HP added additional cache flush queues to separate the flushing of cache for rotating rust and SSD devices.
This is only a short blog post. Just got an e-mail from the DataCore Support. They found a critical bug in SANsymphony-V 10.0.0.0 which should be fixed with Update 1. Only VMware customers are affected, because the bug is related to VMware Thin Provisioning Thresholds. Update 1 is planned for early September 2014. If you’re running SANsymphony-V 10.0.0.0 open an incident at the DataCore Support to get an available hotfix. If you have planned to update to SANsymphony-V 10, delay this update until the release of SANsymphony-V 10 Update 1.
