Last week I did a VMware vSphere and VMware View 4 to 5 upgrade. The ESXi servers for the VMware View environment uses Fusion-IO (HP IO Accelerators) PCI flash cards for there non-persistent VDI pools. After the upgrade to vSphere 5.1 I imported the latest Fusion-IO drivers and created a baseline in vSphere Update Manager (VUM) and deployed the new drivers to the cluster.
After the installation of the Fusion-IO drivers on the ESXi hosts, the Fusion-IO card was not listed in the vSphere (Web) client. Via SSH I make a connection the the ESXi servers. When i run the fio-status command the following warning appeared:
Driver is in Minimal mode: The firmware on this device is not compatible with the currently installed version of the driver.
ACTIVE WARNINGS: The ioMemory is currently running in a minimal state.
The warning means that the firmware needs to be upgraded. I uploaded the firmware to a central datastore and run the following command:
When the firmware upgrade completed, the ESXi servers needed to restart.
After the rebootI checked the status with the fio-status command again. The Fusion-IO card is out of minimal mode.
After the firmware upgrade the Fusion-IO card is listed again.
Unable to connect from the vSphere Client or PowerCLI on Windows XP or Windows 2003 to a vCenter Server 5.5
In my lab environment I still have a Windows XP with the vSphere Client 5.5 installed. When I try to connect with the vSphere Client or vSphere PowerCLI it faisl to connect to the vCenter Server 5.5 or vCenter Server Appliance (VCSA) 5.5. The following errors appears (The OS has a Dutch language installed):
In the release notes of vSphere 5.5 this is a known issue:
vSphere 5.5 uses the Open SSL library, which, for security, is configured by default to accept only connections that use strong cipher suites. On Windows XP or Windows Server 2003, the vSphere Client and vSphere PowerCLI do not use strong cipher suites to connect with vCenter Server. The error No matching cipher suite is shown on the server side, and the handshake fails on the vSphere Client or vSphere PowerCLI side.
There are three workarounds for this:
- Using Windows hotfixes on the Windows XP / 2003 OS
- Adjusting the vCenter Server configuration
- Adjusting the vCenter Server Appliance (VCSA) configuration
In the following steps I will adjust the vCenter Server Appliance configuration:
- Open a SSH connection to the VCSA
- login the appliance (by default this is root and with the passsword vmware)
- Navigate to the /etc/vmware-vpx directory
- Edit the vpxd.cfg file with for example the VI editor (i = insert)
- Add the following <cipherList>ALL</cipherList> between the <ssl> section (see screenshot below):
- Save the changes and quit the VI editor (wq!)
- Restart the vCenter Server service by using the following command: “service vmware-vpxd restart”
After the modification I was able to use the vSphere Client and PowerCLI to connect to the vCenter Server Appliance.

With vCenter Single Sign-On (SSO) 5.5 there is no requirement for a SQL database anymore. SSO 5.5 uses a own VMware Directory Service (VMdir) database. So after the upgrade to SSO 5.5, the Single Sign-On 5.1 database and users can be removed. This is a manual process. In SQL Management Studio remove the SSO (RSA) database and the “ RSA_DBA” and “ RSA_USER” users created.
VMware has released a Network Port Diagram diagram for VMware Horizon View 5.2.
This diagram covers an entire VMware View environment with protocols and port numbers used. In earlier blog posts I already create two small diagrams with protocols and port numbers used by VMware View:
- Tips for implementing a VMware Horizon View Security Server. Link
- VMware Horizon View and HTML access (Blast protocol). Link
The diagram created by VMware can be handy when implementing and troubleshooting VMware Horizon View. Download the diagram here Link
To deliver IT as a Service, VMware has for the coming year(s) the following focus areas:
- Software-Defined Data Center (SDDC). See the VMworld 2013 SDDC recap here Link
- End User Computing (EUC). See the VMworld 2013 EUC recap here Link
- vCloud Hybrid Services (vCHS)
In this last blog post I dig deeper in vCloud Hybrid Services (vCHS) and DAAS announcements.
VMware acquired Desktone to enter the Desktop-As-A-Service (DAAS) market. Desktone offers:
- Self Service of virtual desktops. Simple provisioning from the cloud enables self-service for IT of full VDI, shared session remote desktop service (RDS) desktops and applications without the need to procure hardware or software.
- Multi-tenancy. Each customer gets a separate virtual environment to ensure security while cloud providers are able to manage multiple customers under one platform.
- Grid-based architecture for elastic scalability. Advanced architecture enables unlimited scalability across multiple geographies and data centers.
- Low cost of delivery. Open source based technology eliminates Microsoft licensing fees and third-party software management, resulting in cost savings over competitive desktop virtualization offerings.
The Desktone broker can scale much larger than a VMware Horizon View broker. So it is much more suitable as multi-tenant solution. Another point is that Desktone supports multiple OSes such as Windows Server, Windows Client and Linux as VDI desktop. These desktops can be managed from a single portal, while customer have there own portal in multi-tenant environment.
With Desktone, VMware partners can offer a Desktop-As-A-Service to there customers.
vCloud Hybrid Services (vCHS)
VMware vCloud Hybrid Service, built on VMware vSphere. This enables customers to extend the same applications, networking, management, operations and tools across both on-premises and off-premises environments (private cloud). vCHS is the Infrastructure as a Service (IaaS) public cloud service from VMware.
You can choose two flavors:
- Dedicated Cloud. This option is fully isolated. You get your own vCloud Director instance.
- Virtual Private Cloud. This option runs on physical servers with VMs from other tenants. It is fully isolated from each other.
See the picture below what are the minimum starting resources:
When you choose for example a dedicate cloud you start with 30GHz vCPU, 120GB vRAM, 6 TB disk space etc. You pay for Compute, 24 x7 support, persistent disk(s) and the bandwidth you use. Services as firewalls, load balancers, VPNs, DHCP. NAT and redundancy such as HA are free.
VMware will offer a private beta of vCloud Hybrid Service in the United Kingdom (Slough) in Q4, with general availability (GA) planned in Q1 2014.
VMware vCloud Management Marketplace (CMM)
VMware vCloud Management Marketplace (CMM) is a single place were VMware and partners can put there solutions such as Orchestration Plug-ins, Management Packs, Blueprints and Content Packs . Customers can browse and download these tested and validated solutions in there environment.
The Marketplace can be found here link.
