While talking with a colleague, she told me that she would like to know more about NetApp. Unfortunately we don’t have a NetApp system in our lab and playing with customer equipment is… mmh…unfavorable. But there’s a solution for this problem: Simulate ONTAP 8. This software allows you to simulate a 7-Mode or Cluster-Mode (c-Mode) system and to test many of the features. All you need is a VMware Workstation/ Player/ Fusion or an ESXi host.
This is a really short post. A first step can be the configuration of CIFS. This is done using “cifs setup” command. After you’ve setup CIFS, you can create volumes and qtrees, you can share them with you Windows server etc. It’s a good start into your Data ONTAP 8 journey.
All you need is a configured ONTAP 8 simulator instance and a Windows Domain Controller with Active Directory.
One possible use case for the HP VSR1000 is to build IPsec tunnels for secure data transfer. In this post I will show you how to configure a IPsec tunnel between two HP VSR1000. If you need a short introduction, feel free to take a look at this article.
We have two server VMs (in this case Windows Server 2008 R2 with SP1) and two HP VSR1000 Virtual Service Router. To simplify I added a vSwitch without uplinks to my ESXi at home. This vSwitch has three port groups. While each VSR1000 is connected to only one site and the WAN port group, the server VMs are only connected to one site. The WAN port group should simulate the WAN link, but in reality WAN can be anything. This is a screenshot of the ESXi vSwitch and port group configuration, as well as the logical setup.
This morning a tweet from Josh Coen (VCDX #129) shocked me a bit:
VCP certifications now appear to have an expiration date associated with them #vmware
— Josh Coen (@joshcoen) March 8, 2014
So far the VMware certification had no expiration date. If you had a VCP for ESX2, this was still valid up to today. I quickly checked my VMware Training account and noticed a tiny exclamation mark above my certifications.

Today I found this neat PowerCLI One-liner in my Twitter timeline:
PowerCLI Einzeiler um den Adapter-Typ einer VM auf Vmxnet3 zu ändern: Get-VM YOUR-VM |Get-NetworkAdapter |Set-NetworkAdapter -Type "Vmxnet3"
— T. Scheller (@bones44) February 28, 2014
A nice side effect of this one-liner is, that the mac-address doesn’t change, as you can see in the screenshots.

Nutanix was founded in 2009 and left the stealth mode in 2011. Their Virtual Computing Platform combines storage and computing resources in a building block scheme. Each appliance consists up to four nodes and local storage (SSD and rotating rust). At least three nodes are necessary to form a cluster. If you need more storage or compute resources, you can add more appliances, and thus nodes, to the cluster (scale out). Nutanix scales proportionately with cluster growth. The magic is not the hardware - it’s the software. The local storage resources of each appliance are passed to the Nutanix Controller VM (CVM). The CVM services I/O and storage to the VMs and is running on each node, regardless of the hypervisor. You can run VMware ESXi, Microsoft Hyper-V and KVM on the nodes. Although the Nutanix Distributed File System (NDFS) is stretched across all nodes, I/O for a VM is served by the local CVM. The storage can be presented via iSCSI, NFS or SMB3 to the hypervisor.
In an earlier blog post I wrote a bit about virtual service routers. Now I want to show you how easily you can deploy a virtual service router in your lab. To do so I have downloaded the the HP VSR1000 Virtual Service Router and the Cisco Cloud Service Router 1000V. If you want to know how to download them, just read the mentioned blog post. Because both virtual service routers delivered as OVA, I can easily deploy them through the vSphere Client (sorry, no Web Client. It’s a standalone HP Micro Server without a vCenter). I will show an example on how to deploy the Cisco CSR1000V. That procedure is exactly the same for the HP VSR1000. The procedure is pretty straightforward. The screenshots are self-explanatory.
Today you can get nearly everything as a virtual appliance. So even a router. Usually virtual router appliances are used for the same purposes as physical router: Connecting different networks. A router is nothing more then a piece of hardware and software. Due to this fact a router can be easily deployed as a virtual appliance. So where do you find router typically? In you datacenter? Yes, but in a datacenter you will deal typically with layer-3 switches rather than a classical router. In you WAN? That’s much warmer. Think of all the CE router in the branch offices, or the router that is running at a SMB customer. Or the small linux VM with IPtables which secures a special VM on your hypervisor. Or public cloud deployments. But what’s the benefit of a virtual router?
| TL;DR: The HP 4Gb Fibre Channel Pass-Thru Module is (as the name says) 4 Gb Fibre-Channel module. Even if HP delivers the module with 8 Gb SFP+ transceivers, the module can only provide a 4 Gb link. Don't make the same mistake as I did. Just because 8 Gb SFP + are included, it doesn't necessarily mean that the module provides an 8 Gb connection. |
The HP 4Gb Fibre Channel Pass-Thru Module for c-Class BladeSystem (PN 403626-B21) is a interconnect module for the HP BladeSystem c-Class. It’s a simple pass-thru module, which provides a 1:1 non-switched, non-blocking paths between the server blade and a Fibre Channel Fabric. There are several Fibre Channel interconnect modules, like the Virtual Connect 8 Gb Fibre Channel modules (20 or 24 ports) or the Brocade and Cisco 8Gb SAN Switches for HP BladeSystem c-Class. The pass-thru modules is a good choice if the customer has a good Fibre Channel infrastructure and the number of servers is manageable. It’s much cheaper than the Virtual Connect Fibre Channel modules (which require a Virtual Connect Ethernet module for management) or the Brocade or Cisco MDS Fibre Channel switches for HP BladeSystem c-Class. But it also has disadvantages. it only provides a 4 Gb Fibre Channel link! Even if HP delivers the modules with 8 Gb SFP+ transceivers, only a maximum of 4 Gb are possible. Neither the Quick Specs, nor the HP support could make a statement which SFP+ transceivers are included. That 8Gb SFP+ transceivers are included, was a chance finding. Unfortunately HP doesn’t provide a 8 Gb pass-thru module and the 4 Gb pass-thru module doesn’t support 8 Gb connections, even with 8 Gb SFP+ transceivers. If you need a 8 Gb connection you have to use Virtual Connect or Brocade or Cisco MDS Fibre Channel switches.
After nearly 5 months released HP a new version of the HP Service Pack for ProLiant (SPP). The latest release is now 2014.02.
Back in the days there were two software products to update a ProLiant server with the latest firmware, drivers & agents.
the first one was bootable for offline firmware, and also contained Online ROM flash components for online firmware updates. The second was to install/ update the latest drivers and agents. The HP Service Pack for ProLiants (SPP) replaces both. The SPP is a comprehensive software and it’s delivered as a ISO. It can be burned to DVD, installed on a USB stick or extracted and run from the directory. The SPP used the [HP Smart Update Manager (SUM)](The HP SUM can be used as a standalone product.) as deployment tool. The HP SUM can be used as a standalone product.
