In combining Symantec and VERITAS, weve brought two industry
leaders together to provide a more integrated, proactive, and
efficient approach to managing the security and availability of
information as it moves in and out of the infrastructure. Only the
combined capabilities of these two market leaders can provide the
type of integrated, holistic view that businesses require to fully
leverage the value of their information and of the infrastructure
which delivers it.
By managing information in this way, youre better able to ensure
your information is protected, and that it is available to whomever
needs it (and only to those authorized to use it), whenever and
wherever they need it. We call the result information integrity. By
managing the integrity of your information, you develop greater
resilience in your infrastructure, which enables you to reduce the
risk of downtime, risk of data loss, and the risk of lost business.
You are better able to reduce the complexity associated with
increased demands, including regulatory demands, and you are able
to operate more efficiently. Note to presenter: use if you need a
single summary slide on the product categories and the individual
products
Security Infrastructure & Management Defense-in-depth
protection against attacks at all tiers.Due to the evolving threat
landscape, organizations are required to change their security
approach to implement defense-in-depth. This is done via a
combination of protection at the client, server and gateway tiers
to combat blended threat attacks. Integrated Security at all levels
is used to simplify the approach. Strong security information
management and compliance solutions are required to correlate
incidents across tiers and technologies. In addition, due to the
critical nature of threats facing email today, the defense-in-depth
approach must be applied to email this includes SPAM control,
throttling, virus protection and management.Storage Management
Eliminate storage-related downtime and improve disk utilizationFor
the entire enterprise, monitoring and configuring storage
environments providing cross-platform management to improve disk
utilization and eliminate storage-related down-time.Data Management
Simplify the management, protection and recovery of data throughout
its lifecycle, and rapidly recover systemsFrom the desktop to the
data center regardless of the type or size of business, providing
scalable data backup and recovery solutions to protect critical
data, simplify the management of data backup and recovery, and
provide consistent, reliable data protection. Our system recovery
solutions allow organizations to perform bare metal recovery in
minutes and create real-time snapshots without disrupting system
availability. When disaster strikes you can quickly restore data or
failed systems to a specific point in time without taking hours to
manually rebuild and restore data or reinstall from
scratch.Application Service Management Optimize application and
system availability and performance. Application Service Management
(ASM) is a heterogeneous, cost effective and flexible approach that
helps improve system and application uptime and availability by
configuring, monitoring, analyzing, and tuning client and server
devices and associated applications. Proactively address
performance issues before they impact users or application
performance falls below SLA thresholds. ASM also helps maintain
control over client and server devices by discovering,
provisioning, configuring, patching, updating, and retiring
devices. Replication and remote mirroring technologies speed
recovery time to eliminate data loss by making current data
available immediately at an alternate location. From acquisition to
disposal, ASM helps ensure devices remain secure, available, and
compliant with corporate standards.Insight Use knowledge of the
environment to provide actionable intelligence.Collecting vast
amounts of information and turning that into knowledge, then
adapting that knowledge to the changing threat environment enables
the delivery of actionable intelligence to be leveraged by people
and technologies. This requires a complete view of the external
landscape and a keen understanding of the internal environment that
can be brought together and rationalized then delivered to the
appropriate tools that can implement these tasks in accordance with
organization policy to mitigate risk, manage threats, and ensure
business continuity
Let's drill down a second on availability of data. Organizations
need to consider recovery point and the recovery time objectives
when thinking about data and data protection. This is how much data
can you afford to lose, and how long can you afford to be down.
Once that decision has been made, you're very well positioned to
choose which technology is going to be most useful to solve your
problems.
Depending on how your recovery point or recovery time look, you
can select many different kinds of technologies from VERITAS. You
might decide that the application can withstand hours, or even
days, of downtime, so a very simple tape based backup solution
might be enough for you.You may also decide that you've got a
highly transactional mission-critical application, maybe it's an
online web site or maybe it's a trading floor, so you can only
withstand minutes, or even seconds, of downtime. To meet this
demand, you might choose a very highly available clustered and
replicated solution, so that no matter what happens, you can be
taking transactions within seconds of the failure. The good news is
that VERITAS offers a complete suite of software that can provide
both -- an environment which can get by with hours or days of
downtime, or an environment that gets up and running within minutes
or even seconds. So whatever you decide, VERITAS has a
solution.
Now let's look at that a little bit more closely. How can good
software drive down the cost of hardware? First, let's talk about
storage. VERITAS virtualizes storage. What does that mean? It means
we can create a shared pool of storage devices. The way typically
people deploy systems today is they deploy them in silos. The sales
application is sitting on the sales server and talking to the sales
disk. The financial application writes to the financial disk. The
HR application writes to the HR disk. When the sales disk fills up
we don't go and use the empty disk in finance, we go buy another
disk. This causes high utilization rates in most IT shops most
utilize about 50 or 60% at best. To correct this, we can pool those
resources together, share them amongst different applications, and
access them in a uniform way. end-users are able to use the data
they need. Availability is not absolute. Rather, there are
different levels of availability. in general, availability means
that the following conditions are metThe final technology to
discuss today is VERITAS Global Cluster Manager. Global Cluster
Manager provides you the ultimate in availability, because it
allows you to monitor and manage both your local clusters as well
as remote clusters and replication from one Web based GUI. Should a
failure occur at a single site, you can actually failover your
entire site with a single click of a button. The benefits of
VERITAS Global Cluster Manager is first and foremost ease of
management, because this single Web console allows you to manage
your clusters and your replication. In addition, it has built in
automation. Should you have a failure at your primary site, you
would get an email or a page saying the site is down. Receiving
this message, an administrator would log on and verify a true
disaster has occurred. If they feel a disaster has occurred, they
click one button. At that point in time, the entire site is
migrated to the secondary location. The data is mounted. The
applications are turned on, and all of the client traffic can be
redirected to that new IP address at the secondary site. Finally,
Global Cluster Manager is an open solution. It provides the same
management across multiple operating systems, and allows you to
monitor not only VERITAS replication, but also third party
replication. Global Cluster Manager provides you the ultimate in
availability by allowing you to monitor and manage both your
clusters and replication from a single console, while providing a
failover for an entire site with a single click of a button. Key
Message: It is important for companies to have the flexibility to
scale from local high availability to disaster recovery. VERITAS
provides a solution that can scale from LAN, MAN and WAN as simple
as turning on license keys. Integration between Storage Foundation
and Cluster Server ensures not only data is protected in the event
of an outage but also applications are kept running. With a single
solution, VERITAS Cluster Server, a company can provide high
availability to applications in a single datacenter to providing
disaster recovery over wide area. With VERITAS Storage Foundation,
Data can be protected either within a single storage array to
providing disaster recovery and data protection over a wide area
using IP. Its as simple as
that!******************************************************************************More
information on what each configuration provides and the Advantages
and Disadvantages of each:
Local ClusteringShared-storage clusters are considered second
generation clusters, and today are the most prevalent (over
shared-nothing) for providing HA through application failover,
primarily for RDBMS applications, e.g., Oracle, DB2, Sybase, etc.
Questions to ask your customer to see if this infrastructure is
appropriate for their environment:Do you have a storage area
network (SAN) infrastructure?Is your data center in one location or
are other components if your data center in another location near
campus or off site?Are you satisfied with local availability?
Architectural characteristics of this configuration include:A
redundant server, network and storage architecture for application
and data availability through the linking of multiple servers with
shared storage;Systems are linked with private heartbeats, usually
ethernet, which they use to communicate state status VCS uses a
fast proprietary protocol, GAB/LLT, to communicate status;Each
system in the cluster can access the storage of any other
system.There is no replication or mirroring of data, as opposed to
a shared-nothing or stretch clusterA SAN facilitates larger
clusters (> 2 nodes), and is typically present in all clusters,
i.e., switches or hubs are used;All cluster components servers, SAN
infrastructure, storage are co-located on a single site.What
products can be offered to support this solution? VCS and Storage
FoundationAdvantages Applications can be easily migrated from one
server in the cluster to any other server, facilitating application
uptime.Redundant components prevent single point of failure;Use of
SAN enables data access and sharing;DisadvantagesComplexityCost
*********************************************Metro DR with Remote
MirroringThis architecture typically gets deployed when customers
want DR over short distances, and they have a SAN infrastructure in
place. Many VERITAS customers in the Wall Street area have set up
campus clusters with VM mirroring to separate their data centers
over several miles, thus providing DR against such disasters as
terrorist attacks. This would not provide long distance DR against
a natural disaster such as an earthquake. Characteristics
include:Single VCS cluster spanning multiple locationsCan have
multiple VCS nodes at each site (2 sites maximum)Uses VxVM to
create a mirror with plexes in two locationsNo host or array
replication involvedWith new data switches using DWDM, support for
up to 100KM distances have been claimed. VCS is testing with some
of these.Requires Professional Services to ImplementSeparation
Range dependent on infrastructure providerWhat products can be
offered to support this solution? Storage Foundation and Cluster
Server (or any 3rd party array vendor that provides data
mirroring)
Advantages: Effective configuration for Disaster Recovery at a
low cost Quick restore in the event of a disaster (remote mirroring
is quick always in synch) Maximum use of infrastructure effective
use of fibre infrastructure that company already has in place. Most
disasters are localized and this configuration would protect
against most disasters.Disadvantages: ComplexityCost of DWDM/Fibre
infrastructure. The key to this architecture slide is to emphasize
that a customer who purchases Volume Manager and Cluster Server (or
Foundation Suite/HA) can achieve local availability as well as
metropolitan disaster recovery for no additional costs.
Metropolitan Disaster Recovery (also known as Campus Clustering or
Stretch Clustering) has been a prominent deployment for several
companies whos service level agreements dont require a disaster
recovery site to be across the country. Rather than investing in a
disaster recovery site thousands of miles away, a customer can
invest in a disaster recovery data center in the same city. The
cost savings are tremendous! The minimal requirements is that the
customer has a SAN infrastructure. The distance limitations depend
on the latency that the customer is willing to afford. VERITAS
recommends within 100 km. Remote Mirroring technology found in
Volume Manager is used to replicate the data between the two sites
synchronously. If the customer has already purchased Volume Manager
and Cluster Server, this is a bonus that is part of the feature
set.
A customer example using metropolitan disaster recovery is a
large bank in NYC who has fiber under the Hudson. Their remote site
is in New Jersey. This is sufficient to meet their disaster
recovery needs at an affordable price.
***************************************************************Metro
DR with ReplicationMetro DR with Replication is a VCS, shared
nothing configuration using replication between nodes to allow
geographical separation of the cluster, thus providing both HA and
DR benefits. Due to latency, the separation permitted will not be
as extensive as a wide-area, TCP/IP solution, but RDC does provide
a straight-forward, single cluster solution for many DR
scenarios.The replication must be synchronous. Currently, VVR and
SRDF replications are supported. The solution supports a cluster
with 32 nodes. X number of nodes can be at the primary site, Y
nubmer of nodes at the secondary site. In the event of a failure,
VCS will attempt to failover the service group on a node at the
primary site first before failing over to the remote site.A
question associated with this architecture is when to position it
over the campus cluster solution with VM mirroring. The general
rule is that if a customer does not want to invest in a SAN, they
can just run private Ethernet networks for VCS heartbeating, and
set up Metro DR with Replication. If the customer has a SAN
infrastructure in place, they would implement Metro DR with Remote
Mirroring. This configuration is supported with VVR, SRDF and True
Copy in a Solaris environment and SRDF only in a Windows
environment. There are distance limitations to this configuration.
Distance can be greater than a campus cluster architecture but less
than DR (WAN) architecture. This is due to LLT (heartbeat)
connections. This configuration can be stretched as far as the
network latency for LLT is acceptable. This generally means no more
than 500ms (1/2 second) return trip response between the two
sites.
**********************************************************Wide
Area Disaster RecoveryGCM is both a management solution and a DR
solution, involving multiple VCS clusters. Of the HA and DR
solutions offered by VERITAS, it is the only one which involves
multiple clusters. The stretch clusters use multiple sites, but
always a single cluster. GCM is used for DR where unlimited
geographical separation is called for, or for when management from
a single console is needed to manage an enterprises clusters
worldwide.The management solution (Base Option) does not implement
replication. The DR option, which builds on the Base Option, always
uses replication, either host-based from VERITAS, or array based,
from 3rd party vendors like EMC (SRDF), or HDS
(TruCopy).Advantages: Can support any distanceMultiple replication
