PowerShell is a fantastic way to automate just about everything in a Windows and VMware environment, enabling your IT department to do with more with less, which is the must-have skill of today.

Unix aficionados switching to PowerShell may at first struggle with how to recreate their favorite functionality from Unix land, like grep and awk. PowerShell can do all the powerful string manipulations that awk/sed/perl can do, just in a different manner.

For example, a typical Linux scenario using awk and grep might be:

grep “somestring” foo.txt | awk ‘{print $2}’

The powershell equivalent is below:

select-string -pattern “somestring” foo.txt | foreach { $_.ToString().split(” “)[2] }

The very excellent PowerShell Community Extensions also provide some nice items you may desire from Unix/Linux toolbox.

Now that VMware Data Recovery 1.0 (vDR)  is released and  included with many VMware  bundles ( Other than VMware Essentials and VMware Standard Edition),  customers ask us questions on when to use vDR  1.0 vs. an enterprise solution like Veeam Backup and Replication 4.1. ( HiperLogic sells/supports both products.)

Our general opinion is that vDR 1.0 is not a production level backup tool yet , and everything vDR 1.0 does, Veeam Backup and Replication does ( e.g. data deduplication,  VSS support, full VM and file level recovery, etc). 

Note that vDR is a 1.0.x release. VMware rolls out great features on an aggressive schedule. However,  if 1.0, 1.01, 1.0.2, 1.2  bugs/issues with your backups gives you trouble sleeping at night, stick with Veeam Backup and Replication or similar enterprise level tool that is time tested and customer weathered.

The following table highlights some of the major differentiators that you will want to consider when trying to decide if vDR 1.0 offers sufficient protection for your environment.  

VMware vDR vs Veeam Backup and Replication
Feature VMware vDR Veeam Backup and Replication 4.1
Windows/Linux Image and File Level Recovery Yes Yes
De-duplication of Backups Yes Yes
Suppports more than 100 VMs per appliance No Yes
Full GUI and Command Line/PowerShell support No Yes
Email reporting of backup job status No Yes
Built-in Replication for Disaster Recovery No Yes

This is not an exhaustive list of course, this is just some of the “biggies”. The next release of Veeam Backup and Replication 5.0 will really set a new bar.

A study of companies that lost data in a disaster conducted by the U.S. Small Business Administration revealed 50% never reopened, and 90% went out of business within two years.  With a list price cost of Veeam Backup coming in at less than $1,000 per dual socket ESX server, Veeam Backup continues to be an excellent insurance policy against disaster for SMB and the Enterprise.

Updates ( Last Update 7/13/2010 for vSphere 4.1 )

vDR doesn’t support linked Virtual Center’s.

vDR appliance has a limit of 1TB per data store, max 2 data stores per appliance.

vDR 1.2 Now has File Level Restore (FLR) for use with Linux, though from the 1.2 release notes there are changes to the guests needed to work in many cases 6/11/2010

In these tough times companies are under intense pressure to do more with less. In this post, we look at I/O Virtualization technology that can substantially reduce capital expense by 50%, ensure application performance, and enable 100X more agility in deploying I/O resources. Here is the HiperLogic Top Ten reasons to Adopt Xsigo I/O Virtualization:

#1. 70% Fewer Cables/Cards/Ports

In many installations each server has multiple types and quantities of I/O (GbE, 10GbE, FC), along with all the associated cabling to go with it. The end result is cable spaghetti, which is difficult to manage and maintain.

I/O Virtualization reduces the number of parts involved. Cabling can be scaled back to just one I/O cable per server, and physical I/O cards in each server are replaced by virtual cards. The end result is 70% fewer cards and cables, and significantly fewer switch ports.

I/O Virtualization translates into lower costs, better uptime, and a more flexible environment.

#2. 50% Less Capital Costs. Adios 4U Server

Eliminating cabling, I/O cards, switch ports, all translate into use real dollars saved. Another capital cost savings is the ability use cheaper 1U servers instead of 2U or 4U servers.

Many sites have to use more expensive 2U/4U servers simply because they need to stuff a lot of quad-port ethernet adapters, 10GbE adapters and Fiber Channel HBA cards into a larger chassis.

With I/O Virtualization, only one card is used that replaces ALL of those adapters enabling the purchase of much cheaper 1U servers. Additional savings are realized for the required rack space, power, and cooling.

#3. 100x Greater Agility

I/O Virtualization enables you to adapt your infrastructure on the fly, in real time, without server reboots or resource remapping.

For example, lets say you need to do the simple but time consuming task of adding additional I/O to your server. Right now the process is

1. Schedule downtime for the server
2. Take the server down.
3. Pop open the case and add the additional I/O card.
4. Run the cable to a switch port.
5. Bring the server back online

With I/O virtualization, you just point and click and a new I/O interface appears dynamically on the fly, no need to reboot, no server downtime or having to make a trip to the machine room. Fantastic!

I/O Virtualization also makes server I/O personality independent. One server can quickly adopt the identity of another (WWN, MAC and IP addresses) enabling simpler migration and change configurations.

#4. Do Your Job from Anywhere

I/O Virtualization lets you manage I/O from anywhere. Eliminate that trip to the office or remote data center by doing all of your I/O tasks remotely.

#5. Future Proof Your Data Center

Right now every new I/O technology de jour FC, ISCSI, 10GbE, 8GB FC, FCoE, often means re-cabling and re-architecting. With I/O Virtualization, you can quickly adopt new technologies that you may require without needing to rip out your existing infrastructure or re-cabling.

#6. Unlock Your Blades

If you are implementing blades for your VMware Virtual Infrastructure you will quickly note that the quantity and type of I/O options on blades are very limited. This limitation creates a bottleneck for high VM density.

With I/O Virtualization you are no longer limited by the physical limitations of a blade. You can create up to 44 I/O connections with VMware, or 96 I/O connections with Linux/Windows.

#7. Faster Backups

For hosts on the Virtual fabric you can accelerate the backup process by configuring a low
latency, high bandwidth dedicated backup network, on demand!

This has several advantages compared with
creating a dedicated physical network. First, the virtual network needs to exist only when it is
needed, so the resource is not lying idle outside the backup window. Second, instead of giving every
backup client access to your backup network or backup SAN, you can simply move a secure vNIC or
vHBA from client to client as the backup window requires.

#8. Centralized Management

Quickly monitor, view, and identify issues with a consolidated and centralized view of all your I/O resources in vCenter. Using one tool to manage all of your virtual environment reduces headaches of trying to mash different tools together to solve a problem.

#9. Simplified Disaster Recovery

Virtualizing I/O enabled you to create connectivity at a failover site in seconds for both Physical and Virtual servers. By recreating connectivity from the primary site, DR is greatly simplified.

#10. It’s Real and Shipping

I/O Virtualization is time tested and customer weathered in production at large customer environments. It is not a roadmap, it is a real and shipping solution from companies like Xsigo. I/O Virtualization works with your existing infrastructure, and you can realize the cost savings today. Contact HiperLogic for more details.

A debate is raging on the blogosphere today about Xsigo’s Virtual I/O Technology vs FCoE, with some aruging that Xsigo’s virtualized I/O technology (  leveraging Infiniband Fabric today) will  eventually  be obsolete since DCE/CEE/DCB and FCoE will eventually standardize and will eventually be ubquitious.

The great thing about Xsigo is you don’t have to wait for “eventually” to realize all the benefits of virtualized I/O. Why wait to eventually reduce capital expenditures and increase efficiency when Xsigo Virtualized I/O offers those benefits today.

Note Xsigo’s Virtual I/O technology is fabric agnostic and abstracted away. Xsigo could leverage DCE/CEE/DCB  and maintain all the same Xsigo benefits like swapping I/O personalities, dynamically provisioning I/O on the fly, and dynamically changing I/O resource QoS.

Data Protection Manager 2010 will be able to protect and backup Hyper-V R2 VM’s on CSV storage, and should make backing up Hyper-V VM’s easier.

The beta is currently available for download at:

http://www.microsoft.com/systemcenter/dataprotectionmanager/en/us/2010beta-overview.aspx

There are some nice features for Windows guests, like file level recovery in addition to full VHD recovery.

No Linux VHD or Linux file level recovery it seems ( VMware doesn’t offer Linux guest file level recovery in their VMware Data Recovery either ) so 3rd parties like Veeam that are developing products for Hyper-V will hopefully fill this hole for shops that need Linux support.

Microsoft and RedHat now are doing cooperative tech-support with Windows Server 2003/2008/2008 R2 running on RedHat KVM, and Redhat 5.2 and later running on Hyper-V. Details are here.  Microsoft definitely is improving Linux support on their Hypervisor, though still not at the same level as VMware. There is an updated version of the Microsoft Linux Integration Components for R2 here though I am not sure if this the same code slated for integration into the 2.6.32 Kernel

Pano Logic released version 2.8 of their complete Desktop Virtualization System.

Major new features of this release include:

  • Open Desktop VM’s directly from the Pano Manager.
  • Scalability updated to 1000 devices and 1000 VM’s
  • Office 2007 Optimizations for Excel and PowerPoint documents.
  • Ability to backup Pano database to a Windows share.
  • New $89 USB adapter for dual monitor support with 1920×1200 resolution:

Veeam Monitor 4.5 now includes Business View which enables you to group, view, manage and report on virtual machines based on criteria such as business unit, department, location, purpose and service level agreement.

Before Veeam Business View, VMware Administrators were challenged by the one-dimensional technical view of their Virtual Machines provided by VMware vCenter which shows virtual machines grouped by datacenters, clusters, or hosts.

With Veeam Monitor 4.5, it becomes a snap to view, report, and alarm on multiple business criteria automatically vastly improving the usefulness of monitoring data.

Note Veeam Monitor 4.5 has a free edition, and is available here.

HiperLogic is hosting a Lunch and Learn event on October 14, 2009 in Ypsilanti, Mi with the Veeam engineers showing all the new tools including Veeam Monitor 4.5. To attend please Contact Us.
