Juniper EX Switches

I have just completed a large project that I have just replaced Cisco Switches with the Juniper EX 4200 and 3200 series of switches. The Juniper EX series of switches are designed very well.

The have redundant hot swappable power supplies, which allow you to replace the power supply without replacing the switch. They also have hot swappable fan trays.

Juniper EX series switches also have full 15.4 power over Ethernet across all ports. Most Cisco and HP switches do not provide that in a stackable switch.

Juniper also has a great stacking technology called Virtual Chassis. Virtual Chassis allows you to stack up to 10 ten switches and manage them as one. They have a 128GB back plane and great failover. You can also extend the virtual Chassis to a remote location over 10 GB fiber.

One of the best features I like is the ability to compare configuration changes from command line. You can compare a current config, to an older configuration and see the changes. You can also rollback a configuration if a mistake is made.

They also have a very clean WEB UI that is easy to use and allows you to do a majority of the changes you will need.

Finally, they have layer 3 build into each switch. I was able to move my client to a Layer 3 configuration and provide them fail over of less than 1 second. I could not do that in the prior environment.

The local Juniper SE was also very helpful in the process. Staying late to ensure the project was successful. Overall I think Juniper does a very good job in the Channel and will ensure their customers are treated right.

They also take care of their partners with extra help when needed. Overall, I think you should consider reviewing Juniper before making your next switch upgrade. You can find more information about Juniper Switches here http://www.juniper.net/us/en/products-services/switching/.

Virtualization

We have been working on numerous Virtualization projects using either VMWARE or Citrix XenServer this year. This technology has been big in the enterprise the last few years and is staring to take off in the small to medium business market.

For a small business, you can get into virtualization for no cost. You just have to purchase the correct server. We have been recommending that for a few of our clients. They have the ability to consolidate older hardware and also make better use of their hardware. It also puts the correct pieces into place to allow them to move to a DR very easily.

VMWARE and Citrix Xenserver both have free options available. You can start out with the free option and then upgrade to the premium edition when you are are ready.

I think all small to medium businesses should consider virtual servers. VMWARE and Citrix both make it easy to start.
