Cisco unveils new Linksys E4200 high performance home router

January 19th, 2011 at 11:03 AM  574 Comments

Cisco has unveiled their high performance home network router, the Linksys E4200. Not only is this thing feature packed, it comes in a pretty nice looking case for something that will be tucked away and never touched. Maybe Cisco intends to change that and wants you to put this bad boy on your desk for the world to see?

For $179.99, this thing packs a pretty hefty list of features:

  • Simultaneous dual-band (2.4 GHz and 5 GHz) wireless-N
  • 4x Gigabit Ethernet ports
  • USB Storage Port with built-in UPnP AV media server
  • WPA/WPA2 encryption and SPI firewall
  • QoS traffic prioritization
  • 6 internal antennas, 3×3 MIMO

The USB Storage Port lets you add an external USB drive to your network and share files at home or over the Internet. The built-in UPnP AV Media Server allows for streaming of your video and media files to an Xbox 360, PS3, or other UPnP compatible device.

Cisco also has plans to turn the USB port into a Virtual USB port with a future firmware upgrade, this will also enable printers to easily connect to the network so all users in the home can print wirelessly.

Storage Tiering vs Caching

November 12th, 2010 at 9:06 AM  348 Comments

During the first day of Tech Field Day #4 in San Jose we heard from two storage vendors who had two different thoughts on how storage should be configured.  We started out the day with NetApp who went over everything from their new OnTap 8.0.1 software, to the joint venture with Cisco and VMware called FlexPod as well as a presentation from Greg Kleimanon, Director of Marketing, on how NetApp uses caching in their arrays.

NetApp believes their Intelligent caching using Flash Cache is the best way to handle some of the hurdles that customers are facing today.  Kleimanon stated that Tiering is expensive and complicated to manage.  He did comment that there are companies (Like F5, another vendor from a previous Tech Field Day) that have created algorithms to dynamically manage tiering but he echoed that these algorithms are not proven.

The last presentation of the day was from Avere Co-founder/CEO Ronald Bianchini, Jr.  He was very passionate about his product and it showed through the presentation.  Avere uses your current “slow” storage for archive and uses a hybrid of RAM and SAS/SSD drives for faster reads/writes.  This solves the problem of speed in space by using a non traditional process of putting their box with the fast stuff (RAM & SAS/SSD) in front of your traditional SATA slow array.  It uses a algorithm to decide which items should be written/read from the RAM, the SAS/SSD drives or the SATA drives depending on the most efficient way to handle the data.

So what are your thoughts?  Caching or Tiering?

After seeing both presentations I think Tiering as implemented by Avere is the right way to implement the solution.  The way Avere breaks down the data and gives it the most efficient access path to the storage just makes sense.  Look for big things coming from Avere, especially in their FXT Series.

Update:  Here are the videos of the two presentations.  Watch and share your thoughts!

Not everything made by Cisco is made of gold

The scenario:  You’ve found yourself working at a company that is experiencing phenomenal growth.  The employees have actually decupled in the past year and show no signs of slowing in the near future (on this note, when was the last time you saw the “decupled” in print?). You have inherited a network that is truly a Frankensteinian creation that not even the original architects understand any more.  You have noticed that you neither have a working firewall nor a decent VPN system, though Cisco VPN is used by a handful of key employees to connect to a Cisco 1800 series router.  The IP scheme for the organization, which spans three sites, is using the 192.x.x.x address space. You wish to straighten everything out with a minimum of downtime and as seamless as possible for the end-users.  What do you do?

Well, instead of telling you what to do, allow me to tell you what not to do.  Not just that, let me drill into your collective skulls what not to do.  Are you ready?  Here it comes:

Do not, and this is key, so write it down… do not buy a Cisco SA 500 series device.

Cisco doubles density of 9000 series edge router

August 28th, 2009 at 12:19 PM  450 Comments

Cisco announced Tuesday that it would begin selling an enhanced version of its Cisco Aggregation Services Router 9000 Series, which will double the amount of line cards it can hold by introducing new single-slot cards.

The new configuration will allow 16×10 Gigabit Ethernet line cards, delivering over 100 Gbps of bandwidth. Cisco claims that this new configuration leads the industry in density and scalability, unlike some competitors that only can support 50G today.

The 9000 series router is typically used to deliver TV, video on demand, Internet video and other high bandwidth traffic. It is also used by wireless carriers to support their Internet infrastructure.
