Storage FCP SAN

I'm wondering if I run an iostat and see results below if this may be a problem. I'm asking this because I'm not 100% sure my storage admin is telling me the truth. Whenever I do iostat on this database server running Solaris 9 running 4 9.2.0.6 databases all I see is this one disk with activity. Anytime of the day or night. He tells me don't worry about that because it's a virtual device or something. Anyone able to explain this to me or be able to give me some more insight on the subject? Thanks.

We are definitely open to hiring an experienced consultant. But I get the sense from the couple of consultants that I've met with that they have not successfully deployed FCS and they'd be learning on my nickel.
That kind of goes with the territory but the estimate to setup FCS was about $25K (including the cost of an 8-core Xserve).
I'd love to wait until after NAB but we start moving into our new facility on Monday and there's an expectation that we will begin developing an asset management system the first of the year.
If anyone in the LA area knows anyone who has implemented FCS and wouldn't mind showing me your installation or could recommend a consultant I would greatly appreciate it.

Help with FCS/FCP SAN setup - number of LUNS?

Dear all,
I am a newly certified ACMA and have setup a couple of new SANS but now I am having to upgrade an existing xSan 1.4.2 to 2 and in the process I have decided to rebuild from scratch. The SAN is used to support 5 FCP edit bays. Each controller has all 500GB drives. The problem I have found is the number of xRAIDS in the SAN. There are 3 xRAIDs therefore 6 controllers. Using 1 controller and 2 drives mirrored for the meta/journal LUN. One drive as a spare for the controller.
My question is a 2 parter:
1. What is the best use for the rest of this controller?
2. I now have 5 controllers/LUNS. According to best practice for HD video/FCS SANS the video affinity should be in multiples of 4 LUNS. In this case I have 1 extra. What should I use it for as well? Or can the video affinity contain 5 LUNS without issues? I would hope there is a use for this space in FCP.
Any help would be greatly appreciated and my apologies if this question has been asked already recently. I did a search but did not find any posts that could help me. Again any help is appreciated.

If you're using older Xserve RAIDs I would recommend dedicating that one controller to hosting the metadata LUN and nothing else. With the 5 remaining LUNs to you could put 4 in a video lun and the last LUN could be set to an affinity for use for other files. That is, you can associate folders on your Xsan to this LUN/StoragePool, but video files would go in the main video pool.
But If you're rebuilding the SAN you can benchmark/speedtest the SAN with 4 or 5 LUNs in your video storage and see what works best for you.

Cluster Storage : All SAN drives are not added up into cluster storage.

Hi Team,
Everything seems to be working fine except one minor issue which is one of the disk not showing in cluster storage even validation was without any issue, error or warning. Please see the report
below where all SAN disks are validate successfully, and not added into Window Server 2012 storage.

What is best practice for using a SAN with ASM in an 11gR2 RAC installation

I'm setting up a RAC environment. Planning on using Oracle 11g release 2 for RAC & ASM, although the db will initially be 10g r2. OS: RedHat. I have a SAN available to me and want to know the best way to utilise that via ASM.
I've chosen ASM as it allows me to store everything, including the voting and cluster registry files.
So I think I'll need three disk groups: Data (+spfile, control#1, redo#1, cluster files#1), Flashback (+control#2, redo#2, archived redo, backups, cluster files#2) and Cluster - Cluster files#3. So that last one in tiny.
The SAN and ASM are both capable of doing lots of the same work, and it's a waste to get them both to stripe & mirror.
If I let the SAN do the redundancy work, then I can minimize the data transfer to the SAN. The administrative load of managing the discs is up to the Sys Admin, rather than the DBA, so that's attractive as well.
If I let ASM do the work, it can be intelligent about the data redundacy it uses.
It looks like I should have LUN (Logical Unit Numbers) with RAID 0+1. And then mark the disk groups as extrenal redundancy.
Does this seem the best option ?
Can I avoid this third disk group just for the voting and cluster registry files ?
Am I OK to have this lower version of Oracle 10gr2 DB on a RAC 11gr2 and ASM 11gr2 ?
TIA, Duncan

Hi Duncan,
if your storage uses SAN RAID 0+1 and you use "External" redundancy, then ASM will not mirror (only stripe).
Hence theoretically 1 LUN per diskgroup would be enough. (External redundancy will also only create 1 voting disk, hence only one LUN is needed).
However there are 2 things to note:
-> Tests have shown that for the OS it is better to have multiple LUNs, since the I/O can be better handled. Therefore it is recommended to have 4 disks in a diskgroup.
-> LUNs in a diskgroup should be the same size and should have same I/O characteristica. If you now have in mind, that maybe your database one time will need more space (more disks) than you should use a disk size, which can easily be added, without waisting too much space.
E.g:
If you have a 900GB database then does it make sense to only use 1 lun with 1TB?
What happens if the database grows, but only grows slightly above 1TB? Then you should add another disk with 1TB.... You loose a lot of space.
Hence it does make more sence to use 4 disks á 250GB, since the "disks" needed to grow the disk groups can be extended more easily. (just add another 250G disk).
O.k. there is also the possibility to resize a disk in ASM, but it is a lot easier to simple add an additional lun.
PS: If you use a "NORMAL" redundancy diskgroup, then you need at least 3 disks in your diskgroup (in 3 failgroups) to be able to handle the 3 voting disks.
Hope that helps a little.

How can use all vcenter feature such as HA and drs without shared storage

Hi
i have 2 esxi host dl 380g8
but i don't have any shared storage or san now i want use vcenter feature like ha and drs now for use this features do i have to run VSAN?
i readed for for use vsan we have to buy ATLEAST ONE ssd disk is this trure?
ssd disk is necessary?
atleast one ssd disk for each host ?
can use from all of vcenter feature with VSAN ?
please some help me

Hi,
For VSAN you need at LEAST 3 hosts (4 recommended).
Each host must have 1 SSD for read cache/write buffer.
Do you have any storage at all? How about running a NAS such as "OpenFiler" or "FreeNAS". That way you can present shared storage via that way. (I'd use this in Lab only). These NAS O/S's also work as virtual machines so you can turn any disk into shared storage.

Looks like the LUN is not configured correctly on the storage array. The kernel can't take the LUN online.
I have seen this on various boxes, most of the time it was either that the LUN wasn't set online on the SAN box or there is a SCSI reservation on the LUN.
Can you access the LUN from another host?

Shared partition creation (SAN EVA 4400) for OCR/Vote andASM on linux RHEL5

Hi all,
We are going to install database (Oracle 10g) with RAC on Linux Red Hat Enterprise 5. The storage we are using is SAN shared storage, out SAN vendor has finished to configure and present the dsk storage (500 Gb) to the 2 servers, the name of the volume group is VG_ORADATA. this volume will be used for OCR, VOting disk and ASM (database file).
Our problem is to create and configure the shared partition for the 2 servers.
Here is what i want to do, i want to create:
ocr_partition (25 Gb) : for OCR
vote_partition (25 Gb): for Voting disk
oradata_part1 (150 Gb): for database (ASM)
oradata_part2 (150 Gb): for database (ASM)
oradata_part3 (150 Gb): for database (ASM)
The problem is how to create these partiton an dto mount them for the 2 servers, what is the tools we have to use for this tasks. Can i use LVM (Logical Volume Manager) in linux for this tasks.
Thanks for the help and need your help as it's very urgent for us.
Thank you
Raitsarevo.

My thoughts.
1. Your OCR partition size is too high by several orders of magnitudes. Read the docs and size it appropriately.
2. Your Voting disk partition size is also far too large. Again read the docs and size it appropriately.
3. If you have RAC you have one and only one database (not 3)
4. ASM is not a database and requires no room on your SAN. ASM is an instance that must reside on your servers (nodes).
5. Where are you putting your flashback recovery area, archived redo logs, flashback logs, etc?
6. Where are you putting your online backup files?
7. If you have ASM throw the LVM away. It will do nothing for you other than eat CPU.

Failover Cluster Hyper-V Storage Choice

I am trying to deploy a 2 nodes Hyper-V Failover cluster in a closed environment. My current setup is 2 servers as hypervisors and 1 server as AD DC + Storage server. All 3 are running Windows Server 2012 R2.
Since everything is running on Ethernet, my choice of storage is between iSCSI and SMB3.0 ?
I am more inclined to use SMB3.0 and I did find some instructions online about setting up a Hyper-V cluster connecting to a SMB3.0 File server cluster. However, I only have budget for 1 storage Server. Is it a good idea to choice SMB over iSCSI
in this scenario? ( where there is only 1 storage for the Hyper-V Cluster ).
What do I need to pay attention to in this setup? Except some unavoidable single points of failures.
In the SMB3.0 File server cluster scenario that I mentioned above, they had to use SAS drives for the file server cluster (CSV). I am guessing in my scenario, SATA drives should be fine, right?

"I suspect that Starwind solution achieves FT by running shadow copies of VMs on the partner Hypervisor"
No, it does not run shadow VMs on the partner hypervisor. Starwind is a product in a family known as 'software defined storage'. There are a number of solutions on the market. They all provide a similar service in that they allow for the
use of local storage, also known as Direct Attached Storage (DAS), instead of external, shared storage for clustering. Each of these products provides some method to mirror or 'RAID' the storage among the nodes in the software defined storage.
So, yes, there is some overhead to ensure data redundancy, but none of this class of product will 'shadow' VMs on another node. Products like Starwind, Datacore, and others are nice entry points to HA without the expense of purchasing an external storage
shelf/array of some sort because DAS is used instead.
1) "Software Defined Storage" is a VERY wide term. Many companies use it for solutions that DO require actual hardware to run on. Say Nexenta claims they do SDS and they need a separate physical servers running Solaris and their (Nexenta) storage app. Microsoft
we all love so much because they give us infrastructure we use to make our living also has Clustered Storage Spaces MSFT tells is a "Software Defined Storage" but they need physical SAS JBODs, SAS controllers and fabric to operate. These are hybrid software-hardware
solutions. More pure ones don't need any hardware but they still share actual server hardware with hypervisor (HP VSA, VMware Virtual SAN, oh, BTW, it does require flash to operate so it's again not pure software thing).
2) Yes there are number of solutions but devil is in details. Technically all virtualization world is sliding away from ancient way of VM-running storage virtualization stacks to ones being part of a hypervisor (VMware Virtual Storage Appliance replaced
with VMware Virtual SAN is an excellent example). So talking about Hyper-V there are not so many companies who have implemented VM-less solutions. Except the ones you've named it's also SteelEye and that's all probably (Double-Take cannot replicate running
VMs effectively so cannot be counted). Running storage virtualization stack as part of a Hyper-V has many benefits compared to VM-running stuff:
- Performance. Obviously kernel-space running DMA engines (StarWind) and polling driver model (DataCore) are faster in terms of latency and IOPS compared to VM-running I/O all routed over VMBus and emulated storage and network hardware.
- Simplicity. With native apps it's click and install. With VMs it's UNIX management burden (BTW, who will update forked-out Solaris VSA is running on top of? Sun? Out of business. Oracle? You did not get your ZFS VSA from Oracle. Who?) and always "hen and
chicken" issue. Cluster starts, it needs access to shared storage to spawn a VMs but VMs are inside a VM VSA that need to be spawned. So first you start storage VMs, then make them sync (few terabytes, maybe couple of hours to check access bitmaps for volumes)
and only after that you can start your other production VMs. Very nice!
- Scenario limitations. You want to implement a SCV for Scale-Out File Servers? You canont use HP VSA or StorMagic because SoFS and Hyper-V roles cannot mix on the same hardware. To surf SMB 3.0 tide you need native apps or physical hardware behind.
That's why current virtualization leader VMware had clearly pointed where these types of things need to run - side-by-side with hypervisor kernel.
3) DAS is not only cheaper but also faster then SAN and NAS (obviously). So sure there's no "one size fits all" but unless somebody needs a a) very high LUN density (Oracle or huge SQL database or maybe SAP) and b) very strict SLAs (friendly telecom company
we provide Tier2 infrastructure for runs cell phone stats on EMC, $1M for a few terabytes. Reason? EMC people have FOUR units like that marked as a "spare" and have requirement to replace failed one in less then 15 minutes) there's no point to deploy hardware
SAN / NAS for shared storage. SAN / NAS is an sustained innovation and Virtual SAN is disruptive. Disruptive comes to replace sustained for 80-90% of business cases to allow sustained live in a niche deployments. Clayton Christiansen\s "Innovator's Dilemma".
Classic. More here:
Disruptive Innovation
http://en.wikipedia.org/wiki/Disruptive_innovation
So I would not consider Software Defined Storage as a poor-mans HA or usable to Test & Development only. Thing is ready for prime time long time ago. Talk to hardware SAN VARs if you have connections: How many stand-alone units did they sell to SMBs
& ROBO deployments last year?
StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

How to change Storage Repository on Oracle VM 2.2.2

Edit in place and versioning

Hi
Having built a very fast network to make use of 'Edit In Place' we are surprised to see that Edit in place does not appear to support versioning? i.e we want to drag out a project, work on it and then drag it back into FCserver, where a new version is created. Any thoughts?
There only seem to be hints in the manuals about using EIP, contradicted each time by the statement that 'Checking in and out' is the best way to use FCserver...
Thanks
Dan

Thanks John - I think you made a vital link in my understanding!
I've been messing about this morning and all my problems (touch wood) seem to be resolved after your last comment.
You may remember replying to my thread a while back about metadata... Even that seems to be fixed now!
I think I should outline my workflow - it may help anyone reading!
Firstly, I have changed my compressor cluster to a custom one. I was having problems using 'this computer' cluster; freezing transcodes and i think it was screwing with my Log and Transfer metadata too. Anyway, it tells you how to change it to a custom cluster in the setup guide - takes two minutes. I recommend it, even if you only ever use the admin user to use FCServer like we do.
Ok, the workflow:
-Create a new (filesystem) device with an Edit In Place path using the java client app (not the server pref pane). call it XXX_JOB for example. remember to create a folder in your storage/raid/san first!
Local Directory:
/Volumes/Data/FCSvrDevices/XXXJOB
Macintosh edit-in-place:
file://localhost/Volumes/FCSvrDevices/XXXJOB
(nb: our server has a RAID called 'data', it's share is a mounted as a volume on the local machine called 'FCSvr_Devices')
-Create a production scan for the device - set it off - make sure it is setup to read the correct directory levels for its production name and metadata name. in my experience this takes some fiddling! the workflow example book regarding this setting features a few misprints too!
-In this order; open FCP on the local machine, set the capture scratch to the XXX_JOB device you just made (our devices are on a server volume mounted locally - v.important for EIP to work). Save the project with the exact name you want the production to be - XXX_JOB.fcp. Open log and transfer, add your metadata and set it off. when it is done save your project and close FCP.
Check locally in finder that as a result of changing your scratch you have something like:
FCSvrDevices/XXXJOB/capture scratch/XXXjob/mvixxx.mov
(Where FCSvr_Devices is your storage device/raid/san, XXX_JOB is the new device and mvi_xxx.mov is a file from L&T.)
-If all is well you should soon after have a new production folder called 'XXX_JOB' in FCServer. If you double click this you should see all the files you ingested using L&T. You may now upload your local FCP project to this production. If your Edit In Place has worked properly then you will not duplicate your original media. We do this because we don't want to have any extraneous copies or have to take any unnecessary steps in deleting them.
-When you check this project out you will get a pop up asking you if you want to use original or proxy media. since we are editing in place it doesn't matter. hit 'check out' and only the FCP project will come down. you can now edit away, adding more media as you go from any EIP enabled device - we've found it even works using finder (allowing the use of finder's cool spacebar preview that FCServer doesn't have!). When you check back in FCServer doesnt duplicate any media. you just get a nice new version of your project and no uploading or caching! you can view the assets used in the project by double clicking to 'enter' the project.
This seems to work perfectly now. If anyone has any thoughts as to if this is the best way of doing it i would be interested to know.
Thanks again John

ISE 1.2 VM file system recommendation

Hi,
According to http://www.cisco.com/en/US/docs/security/ise/1.2/installation_guide/ise_vmware.html#wp1056074, tabl 4-1 discusses storage requirement for ISE 1.2 in VM environment. It recommends VMFS.
What are the implications when using NFS instead? Is this just a recommendation or an actual requirement?
At the moment, we use Netapp array which uses NFS for all vApps. It will be difficult to justify a creation an additional FC HBA just for this one vApp. Please explain.
TIA,
Byung

If you refer to
http://www.cisco.com/en/US/docs/security/ise/1.2/installation_guide/ise_vmware.html
It says :
Storage
•File System—VMFS
We recommend that you use VMFS for storage. Other storage protocols are not tested and might result in some file system errors.
•Internal Storage—SCSI/SAS
•External Storage—iSCSI/SAN
We do not recommend the use of NFS storage.

Time to upgrade my machine...HELP!

Alright, so it's time to build up my new mac empire...move up from the very tired Dual G4 I've been using to the next (or at least current) generation.
Basically, I need to go "balls out" on this machine--I'll have about 10k to spend.
I'd like to hear people's suggestions for configurations specific to HDV/HD and graphics processing/editing.
I can tell you now that I'll order the machine with minimal RAM and fill it with aftermarket RAM instantly. Possibly the same with storage.
This includes:
machine-
options-
displays-
hardware-
capture (and other) cards-
accessories-
software-
graphics card (why?)-
storage devices-
best aftermarket RAM-
Firewire (or other) cards-
anything I left out!
Please include non-Apple options as well. I'll basically be setting up the beginnings of my dream editing station here, so think expansion too!
Thanks, and I'll post pics when it's all set up!!
(you can post pics of yours, now, too if you want!)
cheers,
chris
Dual G4 PowerMac 1.42 MDD-build 7W98 Mac OS X (10.3.9) 2 GB RAM, 2 TB storage, FCP Production Suite 4.5

Thanks David...and I will be talking to a VAR...
I also wanted to kind of see what people are using now for what type of workflows, formats, etc. What people like, what potential problems to look out for etc.
As far as MY situation goes...I need a ton of storage, I would like to eventually network the G4 system I have now together as a second workstation for an asst. editor, and my display needs are probably going to be met with dual Apple 20" flat panels, or by a (dual) aftermarket display solution.
As for a capture card, I also will need to have an NTSC Pro Video Monitor (HD if I can afford it) and a capturing solution for varying formats (DSR-45 and/or another deck) I'd like to be able to expand easily to a basic audio production machine at some point in the future as well.
Finally, can one even GET a regular G5 anymore? I'm a bit paranoid about the 1st generation of Intels. Should I be??
thanks!

How to choose a right server for Oracle Database!

Hi all,
Is there any formular that allows me to find the appropriate server configuration for Oracle database 11g?
Please help!
Thank you all.
Dan.
Edited by: Dan on 01:45 06-01-2013

Simply put ... no.
Determining the correct server is a dance between hardware vendors (one point of input to be treated with general distrust), internal expertise and experience working with similar systems, and most importantly understanding the behaviour of what you are building.
Here are some sample questions to start the ball rolling.
1. What operating system expertise does your organization have?
2. What operating system expertise is readily available in the community from which you hire applicants?
3. What type of application?
4. What are up-time expectations?
5. Requirements for high availability?
6. Requirements for time to perform a full recovery?
7. Requirements for security?
8. Storage footprint (dictates internal storage versus SAN, NAS, or ZFS)
9. Anticipated growth (3-7 years)
Everyone wants to sell you CPU clock-ticks, more RAM, more IOPS, etc. But the first thing you need to understand is the capabilities you require that are generic: Required of any solution. Only when you have a clear understanding of these factors are you ready to discuss whether the solution is a pizza box or an ODA ... an Exadata or an IBM System Z.
Far too often I find people purchasing RAM they don't need with CPU speeds that exceed the ability of their network infrastructure to move the data so pay special attention when you are ready to make your purchase to engineered systems like the ODA.

In the first place a 'blue screen' has to be analyzed on the OS side, Oracle COULD be the reason, but who knows? More likely a hardware problem (RAM,disk storage). So you have to ask your system administrator and/or call Microsoft support. Or you try to find an answer in one of the many articles in the web, for example this:

Does WCS run on Windows 2008 R2 server?

Can anybody share his/her experience with running WCS on Windows 2008 R2 server?
Is it possible and did you experience any problems with it? (during installation or during normal usage)
Is it supported by Cisco already?
Our distributor is a little bit vague about that, that's is why I am asking it here.

From WCS 7 release notes :
Operating Systems Requirements
The following operating systems are supported:
•Windows 2003/SP2 and Windows 2003 R2/SP2 32-bit installations with all critical and security Windows updates installed.
Windows 2003/SP2 64-bit installations are not supported. A 32-bit operating system running on a 64-bit capable hardware is supported.
Windows 2003 32-bit installations provide support for up to 64 GB of RAM if Physical Address Extension (PAE) is enabled. See the Windows documentation for instructions on enabling this mode.
•Red Hat Linux Enterprise Server 5.X 32-bit operating system installations.
Red Hat Linux Enterprise Server 5.X 64-bit operating system installations are not supported. A 32-bit operating system running on a 64-bit capable hardware is supported.
•Windows 2003 and Red Hat Linux version support on VMware ESX version 3.0.1 and above with either local storage or SAN over fiber channel.
Individual operating systems running WCS in VMware must follow the specifications for the size of WCS that you intend to use.
No Windows 2008 ! I know lots of people have been crying for it and it should be coming in next releases but no promises as of now :-(
