Cloud security: the grand challenge In addition to the usual challenges of developing secure IT systems, cloud computing presents an added level of risk because essential services are often outsourced to a third party. The externalized aspect of outsourcing makes it harder to maintain data integrity and privacy, support data and service availability, and demonstrate compliance. In effect, cloud computing shifts much of the control over data and operations from the client organization to their cloud providers, much in the same way organizations entrust part of their IT operations to outsourcing companies. Even basic tasks, such as applying patches and configuring firewalls, can become the responsibility of the cloud service provider, not the user. This means that clients must establish trust relationships with their providers and understand the risk in terms of how these providers implement, deploy, and manage security on their behalf. This trust but verify relationship between cloud service providers and consumers is critical because the cloud service consumer is still ultimately responsible for compliance and protection of their critical data, even if that workload had moved to the cloud. In fact, some organizations choose private or hybrid models over public clouds because of the risks associated with outsourcing services. Other aspects about cloud computing also require a major reassessment of security and risk. Inside the cloud, it is difficult to physically locate where data is stored. Security processes that were once visible are now hidden behind layers of abstraction. This lack of visibility can create a number of security and compliance issues. In addition, the massive sharing of infrastructure with cloud computing creates a significant difference between cloud security and security in more traditional IT environments. Users spanning different corporations and trust levels often interact with the same set of computing resources. At the same time, workload balancing, changing service level agreements, and other aspects of today's dynamic IT environments create even more opportunities for misconfiguration, data compromise, and malicious conduct. Infrastructure sharing calls for a high degree of standardized and process automation, which can help improve security by eliminating the risk of operator error and oversight. However, the risks inherent with a massively shared infrastructure mean that cloud computing models must still place a strong emphasis on isolation, identity, and compliance. Cloud computing is available in several service models (and hybrids of these models). Each presents different levels of responsibility for security management. Figure 1 on page 3 depicts the different cloud computing models. READ MORE>
Brocade Unlocks the Power of the Cloud Through Open, Multi-Vendor Virtual Compute Blocks

“Procedures for replacing or adding nodes to an existing cluster” Scope and Objectives The scope of this document is two fold. The first section provides a procedure for replacing existing nodes in a SVC cluster non-disruptively. For example, the current cluster consists of two 2145-8F4 nodes and the desire is to replace them with two 2145-CF8 nodes maintaining the cluster size at two nodes. The second section provides a procedure to add nodes to an existing cluster to expand the cluster to support additional workload. For example, the current cluster consists of two 2145-8G4 nodes and the desire is to grow it to a four node cluster by adding two 2145-CF8 nodes. The objective of this document is to provide greater detail on the steps required to perform the above procedures then is currently available in the SVC Software Installation and Configuration Guide, SC23-6628, located at www.ibm.com/storage/support/2145. In addition, it provides important information to assist the person performing the procedures to avoid problems while following the various steps. Section 1: Procedure to replace existing SVC nodes non-disruptively You can replace SAN Volume Controller 2145-8F2, 2145-8F4, 2145-8G4, and 2145-8A4 nodes with SAN Volume Controller 2145-CF8 nodes in an existing, active cluster without taking an outage on the SVC or on your host applications. In fact you can use this procedure to replace any model node with a different model node as long as the SVC software level supports that particular node model type. For example, you might want to replace a 2145-8F2 node in a test environment with a 2145-8G4 node previously in production that just got replaced by a new 2145-CF8 node. Note: If you are attempting to replace existing 2145-4F2 nodes with new 2145-CF8 nodes do not use this procedure as you must use the procedure specifically for this sort of upgrade located at the following URL: ftp://ftp.software.ibm.com/storage/san/sanvc/V5.1.0/pubs/multi/4F2MigrationVer1.pdf This procedure does not require changes to your SAN environment because the new node being installed uses the same worldwide node name (WWNN) as the node you are replacing. Since SVC uses this to generate the unique worldwide port name (WWPN), no SAN zoning or disk controller LUN masking changes are required.READ MORE>
United States Army Advances Ethernet Infrastructure to Optimize Applications and Deliver Mission-Critical Military Information
Brocade Improves Business Continuity With Non-Stop Networking and Maximum Performance
SAN JOSE, CA -- (MARKET WIRE) -- 06/01/11 --
Brocade (NASDAQ: BRCD) today announced it is working with the United States Army as part of the Installation Information Infrastructure Modernization Program (I3MP) at Fort Carson
to create a highly resilient network to support advanced voice, video
and critical military applications in an effort to modernize the base's
core enterprise information infrastructure. This installation represents
one of the largest core-to-edge deployments of 100 Gigabit Ethernet (GbE)-ready routers and 10 GbE aggregation and LAN switches.
Fort Carson, winner of the Network Enterprise Center (NEC) of the Year award, is a United States Army installation located in Colorado. Its 137,000-acre facility is home to critical members of the military, including the 4th Infantry Division, the 10th Special Forces Group, the 71st Ordnance Group (EOD), the 4th Engineer Battalion, the 759th Military Police Battalion, the 10th Combat Support Hospital, the 43rd Sustainment Brigade and the 13th Air Support Operations
Squadron of the United States Air Force. Due to the
sheer number of users requiring more bandwidth to support emerging forms
of external and inter-base network communication, Fort Carson
required an infrastructure refresh that would provide scalability for
growth while simplifying the delivery of latency-sensitive voice, video
This mission-critical imperative was successfully solved by deploying 100 GbE-ready Brocade® NetIron® XMR
Multiprotocol Label Switching (MPLS) IPv6-ready core routers as the
backbone of the network. The MPLS capabilities provide superior
efficiency, Quality of Service (QoS) and reduced latency times for
critical online applications and services. As a result, Fort Carson's
personnel can minimize network bottlenecks by prioritizing their
delay-sensitive traffic over a path with minimal hops and lower
congestion -- helping boost overall productivity and expedite response
to urgent situations.
In the federal government, network manageability is a top priority for
IT managers. A challenge has been deploying scalable solutions that are
cost-effective and do not degrade or impair network performance. Through
the use of Brocade IronView® Network Manager,
customers can leverage the power of sFlow scalability and wire-speed
operation to deliver a network-wide solution for detecting and
monitoring network traffic without impacting application performance.
This is a significant advantage over alternative network management
solutions that are limited in their scope and that can impact
performance when implemented as inline appliances.
The entire Brocade network solution meets the stringent Defense Information Systems Agency
(DISA) Joint Interoperability and Test Center (JITC) requirements. DISA
JITC's mission is to support the war-fighter with direct technical
assistance and to conduct performance and interoperability testing and
certification for net-centric strategic voice, video and data networking
systems integral to the Department of Defense (DoD) Global Information Grid.
"The selection of Brocade by the United States Army's I3MP
program is a significant win for Brocade, highlighting our proven
expertise in providing high-performance, non-stop networking solutions
to government organizations worldwide," said John McHugh,
chief marketing officer, Brocade. "By meeting the I3MP network and
service requirements, Brocade is well-positioned to further extend its
market presence within the government sector as a leading networking
provider to support and optimize mission-critical applications."

ProtecTier deduplication offers 25-to-1 reduction and online backup
In June, IBM debuted ProtecTIER* deduplication solutions
for AIX* and IBM i. ProtecTIER offers solutions to those who can’t
complete backup operations in a given window, have difficulty protecting
rapidly growing amounts of data or find their current backup
With data amounts growing, deduplication is becoming a vital part of
data management, backup and recovery. “One of the reasons ProtecTIER is
so crucial is because of the crazy growth the world is experiencing as
it moves to an all-digital environment,” says Victor Nemechek,
ProtecTIER deduplication offering manager at IBM. “Customers are finding
their data often doubles or more every year and their current backup
systems make it difficult to capture that data, protect it and restore
it when they need to.”
For backups many companies use tapes that load data quickly, but
present retrieval problems. These challenges—along with reliability
problems—sent customers to disk where data was more accessible, but also
expensive. Companies used disk for small portions of their most
critical data, and kept their other data on tape. “Even with disk for
critical data, backup is still an issue because you have a primary disk
that you store your data on and you have to have that much disk to back
up to, basically doubling your disk needs, and that can be very
expensive,” Nemechek says.
“Deduplication can squeeze 25 terabytes of data down to only
1 terabyte of physical disk, so customers can have the speed and
reliability of disk but without that one-to-one cost.” —Victor Nemechek,

Cisco’s apparently going to try to simplify its sales, services and engineering organizations in the next 120 days
Faced with a nasty loss of credibility, a string of poor financial
results, shrinking market share in its core business, an unwieldy and
alienating bureaucracy blamed for the top executive exodus it been
experiencing, and a stock price that's plunged into the toilet Cisco,
once an economic bellwether, is promising to do more than simply kill
off its once-popular Flip video camcorder business and lay 550 people
off, an admission that its foray into the consumer segment had largely
It said in a press release issued Thursday morning that it's going to
a "streamlined operating model" focused on five areas, not apparently
the literally 30 different directions it's been going in although it did
say, come to think of it, something about "greater focus" so maybe it's
not really cutting back.
These focus areas are, it said, "routing, switching, and services;
collaboration; data center virtualization and cloud; video; and
architectures for business transformation."
Nobody seems to know what that last one is and the Wall Street
Journal criticized Cisco for not being able to explain in plain English
what it's doing and Barron's complained that it needed a Kremlinologist
to decrypt the jargon in the press release.
Anyway Cisco's apparently going to try to simplify its sales,
services and engineering organizations in the next 120 days or by July
31 when its next fiscal year begins. Well, maybe not everything, it
warned, but sales ought to be reorganized by then.
This streamlining seems to mean that:
Field operations will be organized into three geographic regions
for faster decision making and greater accountability: the Americas,
EMEA and Asia Pacific, Japan and Greater China still under sales chief
Services will follow key customer segments and delivery models still under its multi-tasking COO Gary Moore;
Engineering, still reporting to Moore, will now be led by
two-in-a-box Pankaj Patel and Padmasree Warrior and aside from the
company's five focus areas there will be a dedicated Emerging Business
Group under Marthin De Beer focused on "select early-phase businesses"
"with continued focus on integrating the Medianet architecture for video
across the company."
Lastly, it's going to "refine" - but apparently not dismantle its
hydra-headed, decision-inhibiting Council structure blamed for
frustrating and running off key talent - down to three "that reinforce
consistent and globally aligned customer focus and speed to market
across major areas of the business: Enterprise, Service Provider and
Emerging Countries. These councils will serve to further strengthen the
connection between strategy and execution across functional groups.
Resource allocation and profitability targets will move to the sales and
engineering leadership teams which will have accountability and direct
responsibility for business results."
It's unclear whether any of this means layoffs.
Cisco piped in a quote credited to Moore saying. "Cisco is focused on
making a series of changes throughout the next quarter and as we enter
the new fiscal year that will make it easier to work for and with Cisco,
as we focus our portfolio, simplify operations and manage expenses. Our
five company priorities are for a reason - they are the five drivers of
the future of the network, and they define what our customers know
Cisco is uniquely able to provide for their business success. The new
operating model will enable Cisco to execute on the significant market

Load Balancers Are Dead: Time to Focus on Application Delivery 2 February 2009 Mark Fabbi Gartner RAS Core Research Note G00164098 When looking at feature requirements in front of and between server tiers, too many organizations think only about load balancing. However, the era of load balancing is long past, and organizations will be better served to focus their attention on improving the delivery of applications. Overview This research shifts the attention from basic load-balancing features to application delivery features to aid in the deployment and delivery of applications. Networking organizations are missing significant opportunities to increase application performance and user experience by ignoring this fundamental market shift. Key Findings
Enterprises are still focused on load balancing.
There is little cooperation between networking and application teams on a holistic approach for application deployment.
Properly deployed application delivery controllers can improve application performance and security, increase the efficiency of data center infrastructure, and assist the deployment of the virtualized data center.
Network architects must shift attention and resources away from Layer 3 packet delivery networks and basic load balancing to application delivery networks.
Enterprises must start building specialized expertise around application delivery
What you need to Know IT organizations that shift to application delivery will improve internal application performance that will noticeably improve business processes and productivity for key applications. For external-facing applications, end-user experience and satisfaction will improve, positively affecting the ease of doing business with supply chain partners and customers. Despite application delivery technologies being well proved, they have not yet reached a level of deployment that reflects their value to the enterprise, and too many clients do not have the right business and technology requirements on their radar. Analysis What's the Issue? Many organizations are missing out on big opportunities to improve the performance of internal processes and external service interactions by not understanding application delivery technologies. This is very obvious when considering the types of client inquiries we receive on a regular basis. In the majority of cases, clients phrase their questions to ask specifically about load balancing. In some cases, they are replacing aged server load balancers (SLBs), purchased before the advent of the advanced features now available in leading application delivery controllers (ADCs). In other cases, we get calls about application performance challenges, and, after exploring the current infrastructure, we find that these clients have modern, advanced ADCs already installed, but they haven't turned on any of the advanced features and are using new equipment, such as circa 1998 SLBs. In both cases, there is a striking lack of understanding of what ADCs can and should bring to the enterprise infrastructure. Organizations that still think of this critically important position in the data center as one that only requires load balancing are missing out on years of valuable innovation and are not taking advantage of the growing list of services that are available to increase application performance and security and to play an active role in the increasing vitalization and automation of server resources. Modern ADCs are the only devices in the data center capable of providing a real-time, pan-application view of application data flows and resource requirements. This insight will continue to drive innovation of new capabilities for distributed and vitalized applications. Why Did This Happen? The "blame" for this misunderstanding can be distributed in many ways, though it is largely history that is at fault. SLBs were created to better solve the networking problem of how to distribute requests across a group of servers responsible for delivering a specific Web application. Initially, this was done with simple round-robin DNS, but because of the limitations of this approach, function-specific load-balancing appliances appeared on the market to examine inbound application requests and to map these requests dynamically to available servers. Because this was a networking function, the responsibility landed solely in network operations and, while there were always smaller innovative players, the bulk of the early market ended up in the hands of networking vendors (largely Cisco, Nortel and Foundry [now part of Brocade]). So, a decade ago, the situation basically consisted of networking vendors selling network solutions to network staff. However, innovation continued, and the ADC market became one of the most innovative areas of enterprise networking over the past decade. Initially, this innovation focused on the inbound problem — such as the dynamic recognition of server load or failure and session persistence to ensure that online "shopping carts" weren't lost. Soon, the market started to evolve to look at other problems, such as application and server efficiency. The best example would be the adoption of SSL termination and offload. Finally, the attention turned to outbound traffic, and a series of techniques and features started appearing in the market to improve the performance of the applications being delivered across the network. Innovations migrated from a pure networking focus to infrastructure efficiencies to application performance optimization and security — from a networking product to one that touched networking, server, applications and security staff. The networking vendors that were big players when SLB was the focus, quickly became laggards in this newly emerging ADC market. Current Obstacles As the market shifts toward modern ADCs, some of the blame must rest on the shoulders of the new leaders (vendors such as F5 and Citrix NetScaler). While their products have many advanced capabilities, these vendors often undersell their products and don't do enough to clearly demonstrate their leadership and vision to sway more of the market to adopting the new features. The other challenge for vendors (and users) is that modern ADCs impact many parts of the IT organization. Finally, some blame rests with the IT organization. By maintaining siloed operational functions, it has been difficult to recognize and define requirements that fall between functional areas. Why We Need More and Why Should Enterprises Care? Not all new technologies deserve consideration for mainstream deployment. However, in this case, advanced ADCs provide capabilities to help mitigate the challenges of deploying and delivering the complex application environments of today. The past decade saw a mass migration to browser-based enterprise applications targeting business processes and user productivity as well as increasing adoption of service-oriented architectures (SOAs), Web 2.0 and now cloud computing models. These approaches tend to place increased demand on the infrastructure, because of "chatty" and complex protocols. Without providing features to mitigate latency, to reduce round trips and bandwidth, and to strengthen security, these approaches almost always lead to disappointing performance for enterprise and external users. The modern ADC provides a range of features (see Note 1) to deal with these complex environments. Beyond application performance and security, application delivery controllers can reduce the number of required servers, provide real-time control mechanisms to assist in data center virtualization, and reduce data center power and cooling requirements. ADCs also provide simplified deployment and extensibility and are now being deployed between the Web server tier and the application or services tier (for SOA) servers. Most ADCs incorporate rule-based extensibility that enables customization of the behavior of the ADC. For example, a rule might enable the ADC to examine the response portion of an e-commerce transaction to strip off all but the last four digits of credit card numbers. Organizations can use these capabilities as a simple, quick alternative to modifying Web applications. Most ADCs incorporate a programmatic interface (open APIs) that allows them to be controlled by external systems, including application servers, data center management, and provisioning applications and network/system management applications. This capability may be used for regular periodic reconfigurations (end-of-month closing) or may even be driven by external events (taking an instance of an application offline for maintenance). In some cases, the application programming interfaces link the ADC to server virtualization systems and data center provisioning frameworks in order to deliver the promise of real-time infrastructure. What Vendors Provide ADC Solutions Today? During the past five years, the innovations have largely segmented the market into vendors that understand complex application environments and the subtleties in implementations (examples would be F5, Citrix NetScaler and Radware) and those with more of a focus on static feature sets and networking. "Magic Quadrant for Application Delivery Controllers" provides a more complete analysis and view of the vendors in the market. Vendors that have more-attractive offerings will have most or all of these attributes:
A strong set of advanced platform capabilities
Customizable, extensible platforms and solutions
A vision focused on application delivery networking
Affinity to applications:
Needs to be application-fluent (that is, they need to "speak the language")
Support organizations need to "talk applications"
*What Should Enterprises Do About This?
Enterprises must start to move beyond refreshing their load-balancing footprint. The features of advanced ADCs are so compelling for those that make an effort to shift their thinking and organizational boundaries that continuing efforts on SLBs is wasting time and resources. In most cases, the incremental investment in advanced ADC platforms is easily compensated by reduced requirements for servers and bandwidth and the clear improvements in end-user experience and productivity. In addition, enterprises should:
Use the approach documented in "Five Dimensions of Network Design to Improve Performance and Save Money" to understand user demographics and productivity tools and applications. Also, part of this requirements phase should entail gaining an understanding of any shifts in application architectures and strategies. This approach provides the networking team with much greater insight into broader IT requirements.
Understand what they already have in their installed base. We find, in at least 25% of our interactions, enterprises have already purchased and installed an advanced ADC platform, but are not using it to its potential. In some cases, they already have the software installed, so two to three days of training and some internal discussions can lead to massive improvements.
Start building application delivery expertise. This skill set will be one that bridges the gaps between networking, applications, security and possibly the server. Organizations can use this function to help extend the career path and interest for high-performance individuals from groups like application performance monitoring or networking operations. Networking staff aspiring to this role must have strong application and personal communication skills to achieve the correct balance. Some organizations will find they have the genesis of these skills scattered across multiple groups. Building a cohesive home will provide immediate benefits, because the organization's barriers will be quickly eliminated.
Start thinking about ADCs as strategic platforms, and move beyond tactical deployments of SLBs. Once organizations think about application delivery as a basic infrastructure asset, the use of these tools and services (and associated benefits) will be more readily achieved.
Note: We have defined a category of advanced ADCs to distinguish their capabilities from basic, more-static function load balancers. These advanced ADCs operate on a per-transaction basis and achieve application fluency. These devices become actively involved in the delivery of the application and provide sophisticated capabilities, including:

Systems combining block and file storage maximize benefits of server
The data center of the future
looks an awful lot like data centers of the past in one important respect:
storage demands. While the trend toward server virtualization and consolidation
is transforming the way data centers are being designed, built and managed,
rampant data growth continues to be a limiting factor.
In its annual “Digital
Universe” study, EMC projects a nearly 45-fold annual data growth by 2020. Data
growth was cited as the No. 1 data center hardware infrastructure challenge in a
recent Gartner survey of representatives from 1,004 large enterprises in eight
“While all the top data center
hardware infrastructure challenges impact cost to some degree, data growth is
particularly associated with increased costs relative to hardware, software,
associated maintenance, administration and services,” said April Adams, research
director at Gartner. “Given that cost containment remains a key focus for most
organizations, positioning technologies to show that they are tightly linked to
cost containment, in addition to their other benefits, is a promising
In order to drive down costs
and reduce operational complexity, organizations virtualizing their data centers
and beginning the journey to the cloud require a storage infrastructure that is
both simple and efficient. Unified storage delivers on both counts.
Unified storage is the
combination of block- and file-based storage in the same system with common
management. These multiprotocol systems can be attached to servers via IP and/or
The Road to
Unified storage is an evolving
technology, but not a new technology. A variety of vendors have taken stabs at
providing block- and file-oriented storage in a single box since the late 1990s.
Some of the earliest attempts involved simply putting two machines together in a
single enclosure and then creating a GUI to handle management of both.
Next came NAS gateways, which
used a NAS box as an entry to SAN storage. In this setup, a NAS box provides
file-based access to applications via a LAN port, and then stores the data on a
block-oriented storage array that can be accessed across the SAN. While this
approach accommodates both block and file protocols, it has some disadvantages.
One of the major problems is that data must be transferred twice — once across
the NAS Ethernet connection and again across the Fibre Channel or IP SAN — which
adds to I/O latency. Another issue is that the management of NAS gateways
continues to be separate from the management of SAN arrays.
More recent unified storage
platforms leverage virtualization technology to offer a much deeper integration
of file- and block-based storage. A file system performs I/O to disk blocks
using a common virtualized disk-volume engine. Virtualization allows
administrators to create a seamless pool of unified storage and enables
transparent data movement for tiered storage.
While NetApp introduced unified
storage to the market several years ago, it is now available from most storage
vendors. Many of these solutions include features such as data replication,
incremental snapshots and remote mirroring that contribute to robust business
Aligning Storage with
IT organizations face growing
pressure to transform the data center to meet increasing demands for wider
access to information, transactions and services. To a great degree, this means
creating a technology infrastructure composed of virtualized computing and
networking. By breaking the relationship between applications and the IT systems
on which they run, virtualization frees system administrators from providing
specific hardware with static configurations.
However, many organizations
have found that the benefits of virtualization are offset by increased storage
complexity and expense. For example, the creation of hundreds or even thousands
of virtual server image files often leads to massive storage waste. Because each
of these images is typically many gigabytes in size, the total storage required
in virtual environments can be 30 percent more than in an equivalent physical
environment. As a result, virtual machine sprawl increases operational overhead
and compromises storage utilization efficiency and overall business agility.
Unified storage improves
utilization by allowing organizations to consolidate and virtualize storage
across storage protocols, environments and mixed storage platforms. Combinations
of block storage (Fibre Channel or iSCSI) and file storage (NAS systems with
CIFS or NFS) can be managed via a common set of features such as snapshots, thin
provisioning, tiered provisioning, replication, synchronous mirroring and data
migration — all from a single user interface. This shift toward a shared
infrastructure enables organizations to achieve storage utilization rates of 85
percent or more, compared to the sub-50-percent rates in standalone storage
“IT managers are looking for
storage solutions that not only deliver immediate value, but also enable
flexibility and growth over time, so that storage can adapt to changes in an
organization's applications, user needs or business demands,” said Mark Peters,
senior analyst at Enterprise Strategy Group. “Storage solutions that are both
virtualized and unified are ideal to address the needs for both storage
flexibility and data growth.”
WASHINGTON - 01 Mar 2011:IBM (NYSE:IBM) today announced a major expansion of its Institute for Electronic Government (IEG) in Washington, D.C., adding cloud computing and analytics capabilities for public sector organizations around the world.
