AT A GLANCE:
Microsoft's SharePoint application suite is the most powerful and lexible
collaboration system on the market. The IT infrastructure for SharePoint needs
to be just as powerful and lexible. No matter how much SharePoint grows
and changes, the LeftHand SAN can easily accommodate it. No more add-on
products, complex procedures, high-priced consultants, or months of training,
YOU will be able to change, scale and protect your storage environment on the
ly to accommodate whatever your SharePoint user community throws at it.
INTRODUCTION
Windows SharePoint Services and Microsoft Ofice SharePoint Server
(collectively known as "SharePoint") constitute the connective tissue that binds
together the outputs of ofice workers into a manageable, searchable and
accessible information environment. Gone are the days of unmanaged public
folders, public email folders, intranet wiki sites and lash drives passed from
person to person. SharePoint provides a self-service environment where ofice
workers can take control of information - how it's organized, who gets access
to it, and how it's displayed.
From an IT perspective, SharePoint is a collection of technologies that provides
a server infrastructure to support the needs of information workers. SharePoint
ties together client software such as Word, Excel® Outlook®, and Internet
Explorer® on the desktop, and utilizes Windows ServerTM, ASP.NET, Internet
Information Server, SQL Server, and SharePoint Server itself to create the
infrastructure. At the end of the day, IT staff members are managing server
farms, databases, web servers and server-based applications, just as they are
with any other major distributed application environment.
The storage requirements are tied to the size, use proile, and information
criticality of the SharePoint deployment. Deployments range from single
server, small group implementation housing mostly secondary information, all
the way to large server farms supporting thousands of users against multiple
site collections with massive amounts of highly critical data. Therefore the
speciic deployment of SharePoint will dictate the data protection, performance,
high availability, capacity, storage management and scalability requirements.
...And it will change! By it's very nature, SharePoint will morph and grow to
accommodate new projects and new uses as your corporate user community
learns the system and fully exploits its capabilities.
What is needed is a storage subsystem that is lexible enough to meet a variety
of initial demands, and then adaptable to accommodate changes - without
costing an arm and a leg, or requiring an army of storage experts to manage.
SOLUTION OVERVIEW
SharePoint from a storage perspective is implemented as a set of SQL Server
databases which reside in NTFS volumes. For best performance and reliability,
these volumes should reside on direct attach storage (RAID storage arrays), or
block-level storage on a Fibre Channel (FC)
or iSCSI SAN. An iSCSI SAN from
LeftHand Networks has ive advantages that recommend it as the best choice:
- You get all the storage management features and beneits of a modern,
state of the art SAN (e.g. thin provisioning, replication, high availability,
snapshots).
- The storage is sharable from all servers, making the environment lexible
and scalable as server farms change and grow.
- iSCSI SANs from LeftHand are easy to manage, requiring no speciic array
management or storage networking expertise.
- LeftHand SANs perform as well, and are far more scalable than the
other alternatives.
- You can easily apply additional data protection and HA features as needed
without downtime.
For high-end SharePoint deployments, two storage requirements typically
emerge as central to the storage decision:
- The ability to change storage conigurations on the ly
- The ability to construct a highly available storage environment; one that will
survive virtually any component failure and keep on running with no impact
to SharePoint users
LeftHand Networks iSCSI SANs meet both these requirements. Based on
its patented SAN/iQTM storage management software, a LeftHand SAN is
comprised of multiple "storage nodes", each of which is a self-contained
server with 6 to 12 drives each. A set of storage nodes are clustered together
to create a virtual storage array or storage pool from which iSCSI volumes are
created. SAN/iQ load balances volume data across the storage nodes within
a cluster, and also replicates individual blocks to different storage nodes using
a technology called "Network RAID (nRAID)". The end result is two-fold: First,
the storage subsystem scales simply by adding additional storage nodes
to the storage cluster. Existing volumes are automatically re-balanced to
accommodate the new nodes, and both the capacity and the performance of
the storage cluster is increased. Let us repeat this: A performance bottleneck
relating to the storage subsystem can be immediately solved by adding an
additional node to the storage cluster. No re-planning or re-coniguration.
No downtime. No storage expertise required.
The second beneit of LeftHand's architecture is based on nRAID. nRAID
provides the same level of protection between storage nodes as disk RAID
provides between disks in a RAID array. Thus, if any part of a nodes fails (e.g.
disks, CPU, network connections, power), other copies of the data within the
SAN ensure that the data volumes are still available. The system can even
tolerate most multiple failure scenarios. For example, a drive failure in a
node will be caught by disk RAID. Another drive failure in the same array will
be caught by nRAID. Also, due to the method by which nRAID creates data
replicas, even multiple nodes can go down without interruption of service.
In fact, (here comes the really cool part), by physically locating half of your
storage nodes in one location, and the other half in a different location, you can
suffer the complete failure of a location (a failure of half the storage nodes),
and still keep running! There is no additional product to buy, nothing extra
administratively to do...just put half your nodes in a different location, and
you have instant, multi-site failover capability. Combine this with a Microsoft
Cluster Server environment for your SharePoint databases, and you will
have a complete HA SharePoint environment - all at a price you never
thought possible.
Beyond the key features mentioned above, SAN/iQ has a rich set of additional
storage management features, including:
- Thin provisioning
- Snapshots, remote snapshots between SAN/iQ clusters
- Volume Shadow Copy Service (VSS) support
- Online upgrades of SAN/iQ
- Automated volume growth
- Automated snapshot capacity management
- iSCSI network load balancing (via Microsoft MPIO)
- Central SAN management console with administrative access rights
- Full iSCSI security and server authentication
All these features and more are included in the base SAN/iQ SAN. No ala carte
feature pricing. In short, a LeftHand SAN/iQ SAN is the best storage for running
your SharePoint environment.
THE POWER OF SHAREPOINT AND LEFTHAND NETWORKS SAN/IQ
LeftHand Network's SAN/iQ provides a cost-effective, easy-to-manage,
high scalable, and highly available iSCSI storage environment for use as the
SharePoint storage environment. Your corporate SharePoint infrastructure can
be easily expanded as you add new site collections, new users, or entire new
web collections. If you are starting small, you can go from 1 or 2 servers with
a small 2-node SAN up to servers farms consisting of multiple web servers,
index / SSP servers, and clustered database servers against a 10 or 20 node
multi-site SAN without once having to reconigure your existing volumes, or
ever taking the storage system down.
