Microsoft SharePoint with Cisco ACE

Posted by Ravi shankar on February 15, 2009

Due to large scale end user, the Microsoft needs solution for server load balancing. Microsoft Server 2003 software provides with server load balancing and SSL termination.
However Cisco ACE can offer higher performance for these two applications along with end user access control, server health monitoring and TCP connection management.

Virtualization within Cisco ACE allows the single active-active pair of Cisco ACE product to serve multiple Microsoft SharePoint application as well as other Microsoft and non-Microsoft enterprise application. Additional virtual context can be used along with the Cisco ACE deployed in the data center to accommodate new Microsoft SharePoint application without need to order and configure additional equipment.

Cisco ACE virtualized context can be combined with Cisco ACE Role Based Access control (RBAC), which constrains the commands and action for unique application, database, security and system management administration. Cisco ACE comes repacked with number of predefined roles, others can be customized.

Cisco ACE provides server load balancing session for SharePoint through the source IP methodology. Cisco ACE can decrypt the SSL traffic for intrusion detection and prevention and then can encrypt traffic to the server.

When Cisco ACE is combined with the SharePoint, significant server processing reduction was found.

Microsoft SharePoint with Cisco WASS

Posted by Ravi shankar on February 15, 2009

When a service is requested by the remote user, the transaction is travelled over the wan and introduces network delay that slows end user performance. When the network delay is because of overburdened bandwidth, distance of user to server, or a high number of steps to complete a transaction, end user performance and bandwidth utilization improvement can be achieved by the Cisco WASS technologies such as Data redundancy elimination (DRE), TCP flow optimization (TFO) and compression.

Cisco WASS is combined with Microsoft SharePoint gives significant round-trip time (RTT) and bandwidth reduction.

Data center Application optimization services:

From User to Server:

Application Services are Data center and server load balancing, Server Health monitoring, SSL decryption, TCP congestion consolidation, Security access control

From server to user:

Application services are Caching, Compression, Protocol Optimization, SSL encryption

Cisco WASS for SharePoint Portal Server Optimization

Posted by Ravi shankar on February 15, 2009

Cisco WASS provides WAN optimization capabilities along with application specific acceleration, through devices that are deployed on each side of the WAN. These devices called Cisco WAE Wide Area Application Engine Appliance, are available as router-integrated network modules or as standalone appliances and are deployed out of the data path in the data center and remote office LAN.

Cisco WASS can optimize SharePoint Portal server 2003, improve performance, minimize WAN bandwidth consumption and improve productivity.

Optimization for SharePoint and other associated application is achieved through the following Cisco WASS features:

Application acceleration for Common Internet File System (CIFS) Protocol:

Through file data and Meta data caching, latency mitigation through technique such as read-ahead caching, and local message handling, Cisco WAE can accelerate access to document without incurring latency and bandwidth penalties caused by WAN.

Cisco Data Redundancy Elimination (DRE):

It eliminates the transfer of redundant data segment that have been previously identified. DRE is application independent and can identify pattern within flow from any TCP based application and later use those identified pattern to suppress redundant transmission. DRE is effective for document that is downloaded multiple times and also for document that have changes applied to them.

LZ compression:

To minimize bandwidth consumption, all data is compressed in transit. It can provide 2:1 to 5:1 compression.

Cisco Transit Flow Optimization (TFO):

TFO improves the behavior of TCP in WAN to facilitate high performance, reliability, efficiency when WAN is used. TFO terminates the TCP session locally and transparently optimizes flow that traverses the WAN, thereby shielding communication nodes from the limitation of WAN.

Cisco WASS dramatically reduces response time and bandwidth utilization, provides users with LAN-like access to SharePoint Portal Server and content, thereby improving productivity.

What is Torrent?

Posted by Ravi shankar on February 15, 2009


Bit torrent by definition is just a file transfer protocol. A Bit Torrent client is the application which uses that protocol.

The below given is the list of clients:

BT Plugin for eDonkey
uTorrent – New! (and pretty damned good!)
Bits on Wheels (MAC)
Transmission (MAC)
Tomato Torrent (MAC)

Some important terminology in Torrent client:

Seeder:        The one(s) with the file
A seeder is uploading, to get a file you need at least 1 seed in the swarm

Leecher:    The one(s) without the file (also known as a peer)
A leecher is downloading from a seeder (and most of the time is also uploading to other peers/leechers too)

Tracker:    The thing that keeps track of who has what and what pieces
There are many trackers out there, some public and some private

Swarm:        The group of computers involved with any one particular torrent.
The number of computers that the swarm contains is found by adding the number of seeds to the number of peers.

Ratio:        The amount you have downloaded compared to the amount you have uploaded. If you use Bit Torrent you MUST upload/seed as much as you download/leech

Reseed:        Asking someone to repost a torrent that has no seeds

Client:        The program you use to download Bit Torrent’s

How it works?

The files you download are .torrent files and they are tiny in size (just a few Kbs).  The .torrent just contains information concerning what the file is, how many pieces it has and what tracker it’s going through.  When you click on a .torrent file, you then chose to open it with your bit torrent client (azureus).  You then select your place to save it and your download will begin (hopefully).

In order to get a download – you need seed (ers).  Sometimes the tracker might be down, in which case no one knows who else has the file and it doesn’t work.

A download with lots of seeds and only a few peers will generally be quick, if you have lots of peers and no seeds it will generally be slow.

How far Bit Torrent is flexible?

The main benefit of torrents is its versatility. Because BitTorrent is just a protocol, a way of sharing files, there is no restriction on the type of file you can share. Its popularity also means that you have a wide range of torrents available and the latest releases too.

The big differences with Torrents compared to other P2P networks are:

a) I don’t have to give the whole file to each person to get it out there – I can give a bit too each person

b) Once I have given a bit out, its availability has just increased, because someone else can then also give it out, and so on and so on.  The speed of a torrent will generally get better as more and more people want it – unlike Soul Seek or other P2P apps where you just wait longer to get it!!

c) Torrents technically aren’t illegal.  After all, a torrent is just a tiny little file with no copyrighted content.  It’s a bit muddy water here though, as they can facilitate the transfer of copyrighted content.

Active Directory Trust Relationships

Posted by Ravi shankar on February 14, 2009

In Active Directory, when two domains trust each other or a trust relationship exists between the domains, the users and computers in one domain can access resources residing in the other domain. The trust relationships supported in Windows Server 2003 are summarized below:

Parent/Child trust:

A parent/child trust relationship exists between two domains in Active Directory that have a common contiguous DNS namespace, and who belong to the identical forest. This trust relationship is established when a child domain is created in a domain tree.

Tree Root trust:

A tree root trust relationship can be configured between root domains in the same forest. The root domains do not have a common DNS namespace. This trust relationship is established when a new tree root domain is added to a forest.

Shortcut trust:

This trust relationship can be configured between two domains in different domain trees but within the same forest. Shortcut trust is typically utilized to improve user logon times.

External trust:

External trust relationships are created between an Active Directory domain and a Windows NT4 domain.

Realm trust:

A realm trust relationship exists between an Active Directory domain and a non-Windows Kerberos realm.

Forest trust:

Forest trust can be created between two Active Directory forests.
