minimal hardware requirement for SQL failover clustering

HI,
I would like to build a SQL 2000 failover clustering to improve my network
knowledge. For testing and learning purpose, what's the minimal hareware
requirment?
Best Regards,
Lynn
Hi
Hardware should be from the the Microsoft HCL
But typically:
2 Identical Servers with Minimum 512Mb RAM
4 NICs
1 x SAN
2 x SAN connectivity
Network and other cabling
Or as Uttam answered yesterday:
"
Lynn,
For testing purposes, you may find this useful
Using Microsoft Virtual Server 2005 to Create and Configure a Two-Node
Microsoft Windows Server 2003 Cluster
This guide provides step-by-step instructions for using Virtual Server 2005
to create and configure a two-node server cluster.
http://www.microsoft.com/technet/pro...y/cvs2005.mspx
If you do not want to install virtual server and want to build using minimum
hardware, long ago I had build a two node cluster using two laptops with
SCSI card and one
SCSI disk and a cross-over cable. This is the bare minimum. I also was able
to install SQL Server 2000 clustered instance on this bare min cluster. It
worked and was good
for testing but NOT supported and also it did not work sometimes as
expected. Ofcourse, I would not do this for a real test cluster or dev
cluster.

|||Mike,
Thank you so much for your quick response. It's very useful.
Rihgt now, I already have a machine with 512 RAM, and I would like buy a new
machine with higher hardware component. Is "two identical machines" the
must-be? Or, I can configure two-node failover clustering with two different
hardware component machines.

Lynn

|||Are you looking to build a Highly Available 2-node cluster that is fully supported by Microsoft and the hardware vendor? Or are you just looking to build a 2-node cluster
for testing?
Yesterday, I had already answered for the latter.
For the former -- i.e. to build a highly available cluster supported by Microsoft and hardware vendor, you need a "Qualified complete cluster solution". So, where does
one find the list of complete cluster solutions that are qualified?
The most current Cluster Hardware Compatibility List (HCL) is available at the following Microsoft Web site:
http://www.microsoft.com/hcl (http://www.microsoft.com/hcl)
When you visit this site, click the Cluster category. The Cluster and Cluster/Datacenter categories display only complete cluster solutions that have been qualified. The
subcategories list components that have passed Cluster Component Candidate testing. These cluster components are listed for Original Equipment Manufacturers
(OEMs) and System Integrators to design complete clusters and then submit a complete cluster solution for testing.
The most current Cluster Windows Server Catalog (WSC) is available at the following Microsoft Web Site:
http://www.microsoft.com/windows/catalog/server/ (http://www.microsoft.com/windows/catalog/server/)
When you visit this site, click the Hardware tab, and then click on the Cluster Solutions category. The Cluster Solutions category displays only complete cluster solutions
that have been qualified.
NOTE:
Customers should not use this list to build a cluster solution because using these individual components in a cluster does not qualify as a complete HCL or WSC
solution. Microsoft fully supports only clusters that are complete solutions that are listed in the Cluster category on the HCL or WSC.
To answer you qs "Is "two identical machines" the must-be? Or, I can configure two-node failover clustering with two different hardware component machines."
ANS. Currently today, a vendor can submit a solution for testing / qualification if the hardware is dissimilar. For example a Proliant DL380 as one node and a Proliant
DL580 as another node. But the ENTIRE SOLUTION still needs to be submitted as a COMPLETE SOLUTION and Windows Hardware Quality Labs (WHQL) qualified.
Now it is true that these are rare...

Miniature Clustering Lab

I'm looknig to set up a miniature clustering lab at home and looking for some
advice.
I would like to hopefully keep the price tag to around $750-$1250.
I've already found a couple of boxes that I'm going to use for my nodes
(dual node cluster). I can do all the internal stuff myself (NIC's, etc.).
They each are about $300.
What I need now is shared storage and a switch/hub. I'm new to the
networking side of things. What DO I need: switch, router, etc.? Also, is
there a way to set up things wirelessly? All my big stuff will be in a mini
server room in my basement and my office is upstairs.
If anyone has any advice, I'd really appreciate it.
Thank You!!!
Wireless is probably more of a pain thatn it is worth. A single switch or
hub will be fine. You can use a crossover cable for a two node cluster
heartbeat LAN. As for storage, you can use almost any SCSI drive. get a
self-powered enclosure ($50 or less) , a couple of cables, and a couple of
cheap controllers. I have done it with Adaptec cards, even with mis-matched
ones. It isn't particularly pretty, scalable or stable, but it does work.
One alternative that many people are using is Virtual Server from Microsoft.
Then you have one physical system that can simulate a cluster internally.
Good Luck,

|||Maybe you could give me your unofficial blessing on the following?
- Found a four port hub
- Two servers both with two NICS. One of the NIC's is connected directly to
the hub. This would constitute the two private IP addresses.
- The second NIC's would be a wireless adapters to act as the "public" IP
addresses. This is so I can see them from my office. Not a good idea?
- The network storage is a network storage device I found...160 GB. This
plugs directly into the hub as well? Once plugged into the hub, would I then
configure IP's, subnets, etc. What is the admin interface?
My next dumb question is this: when setting up the hub, do I just plug it in
and go? I've worked on network stuff before , but it's always been set up for
me. I just go in and assign IP addresses, network names, etc.
Thanks again!!

|||Two problems. Wireless NICs almost always use DHCP addresses. Clusters
require hard-coded IP addresses.
NAS is a definite NO-NO for SQL in general and clusters in specific. There
is no way to arbitrate ownership of a NAS or any network storage type device
which completely rules them out for clustering. Direct Attach SCSI, iSCSI,
Virtual SCSI, or Fibre Channel are your options, even in a test and training
environment.

You can use wireless for the public, no worries and the hub for the private.
Your DC will have to be available on the wireless.

Migrating to SQL Server 2005 and Clustering

I have a fairly unique scenario, and I would like to see if anyone can point
out any potential holes of difficulties with this migration plan:
What client has -- 1 SQL Server 2000 enterprise Edition running on SQL 2003
NOT clustered, and using a SCSI disk array.
What client wants -- 2 SQL Server 2005 systems, running on a 2 node cluster
(Active-Passive) using a shared FiberChannel SAN. The active system will be
new, the failover system will be current system listed above. Note that
Clustering HCL has already been verified.
Goals -- provide ability to perform a gradual, testable migration from SQL
Server 2000 to SQL Server 2005 Cluster
Plan:
1) Setup New Server and SAN. Connect Both New server and old server to SAN
2) Install MS Clustering service on both servers, keeping original
un-clustered SQL 2000 in production
3) Install new instance of SQL 2005 on cluster
4) Test and then migrate databases from SQL Server 2000 to new SQL Server
2005 cluster one at a time. This means running the non-clustered SQL 2000 on
the physical hardware as the clustered SQL 2005 failover node. I realize
that failover probably wont work well during the transition, due to a lack of
resources.
5) When transition is complete, remove SQL Server 2000 from failover node.
Any thoughts or comments would be greatly appreciated.
Thanks,
Paul
My only concern is that you are reusing the existing node as a cluster node.
For simplicity's sake, I would create a a clustered installation without
reusing any of the existing hardware. You then have the original system
completely untouched during the transition. You don't need to connect the
existing SQL server to the SAN to do a minimal down time transfer. Given
proper set up time, I can do a server cutover in less than 15 minutes,
regardless of the total database size or count. Since you are moving one DB
at a time, it even gets easier.
If you have to reuse the existing hardware, I would add it to the cluster
after migration is complete. Install the cluster to a single-node, perform
the migration/cutover, and then reload the OS and add the node to the
cluster. You won't have failover redundancy until the project is complete,
but since you don't have that now, you won't miss it.

|||Geoff,
Unfortunately, we do need to re-use the hardware, so your suggestion of
installing a single node cluster sounds like oustanding advice. The lack of
failover during the transition will not be critical.
You mentioned reloading the OS on the current (soon to be failover) server.
Is this neceessary with Windows 2003, or just wise a precaution?
Thanks again!

any problems with 2000-2003 upgrades, but I have had issues with earlier OS
upgrade paths. I have even go so far as to upgrade each node in a cluster
then go back and wipe and reload each node, just so I don't have any
leftover bits. Since you will be migrating a W2000/SQL 2000 standalone host
to a W2003/SQL2005 clustered host, I would definitely wipe the system and
start over. If nothing else, you can guarantee it is an exact OS match for
its peer node.
