ISCSI as primary storage

From the [Deployment Planning Guide|http://docs.sun.com/app/docs/doc/820-2488/aallx?a=view]:
Do not install Directory Server or any data it accesses on network disks.
Directory Server software does not support the use of network-attached storage through NFS, AFS, or SMB. All configuration, database, and index files must reside on local storage at all times, even after installation. Log files can be stored on network disks.
I'm interested in setting up a small Directory Server install (support ~100users for less than a dozen applications) and was wondering if it would be possible to do so under VMWare with iSCSI as primary storage. My planned setup would be multipath iSCSI (2x1GigE) with to a mirrored pair 15k SAS disk residing in a Dell MD3000i enclosure. I understand the general statement above referring to NFS/SMB mounted disks, they just can't compete performance wise with local disks, but I've always viewed iSCSI (especially with proper iSCSI aware switches, dedicated NICs with TCP/IP offloading, multipath, etc) as a middle ground between local storage and NAS storage. I'm sure it will work, but willmy performance suffer?
For the record, this will be under Solaris 10 x64 likely on a dedicated virtual machine, although I have considered zones.
Is there anyone else who has chosen the iSCSI route instead of local storage/FC for their Directory Server setup? Anyone else running it under VMWare? Any gotchas?

The warning isn't about performance as much as about POSIX compliance.
Since NFS or samba didn't fully comply, you could see adverse effects on NFS mounted DBs.
An iSCSI target with a POSIX compliant FS (from a solaris 10 initiator, you should defintely give ZFS a whirl) should work just fine for you, although I don't recall that we've tested that particular setup within DS Engineering or QA.
And yes, performance WILL suffer compared to local storage but is very likely to be better than NFS anyway so I would agree on your calling it a middle ground between DAS and NAS.
Let me know here if you happen to get something interesting with your setup.
cheers

Want to Use eHD for Primary Storage

Good day,
My question basically is: How do I change over to use my eHD as my primary storage instead of using it for back up through Time Machine? AND Can anyone explain how to do it as though I just plugged in a Mac for the first time yesterday?
Background: About 2 years ago with some great advice from people who answered a previous post I purchased a 1TM OWC external HD. I was down to 4GB left available on my internal and I find myself in a similar situation now with only 11.93GB left on my internal HD despite the 1TM eHD which is only a fraction full.
2 years ago when I originally connected my eHD I was given the option to store directly to eHD OR use it for back up through TM. Being a novice to it all and for whatever reason, not sure why exactly but at the time I chose to back up through TM. I was having issues with getting TimeVault turned off and was overwhelmed etc. etc.
Anyhow--flash forward 2 years later I am filling up my internal again with only the 11.93GB left that I mentioned. According to OmniDiskSweeper a good 142.9GB of it is coming from my movies---mostly the events vs. projects of course but 142.9GB none-the-less. I know when I import movies from my camera I can choose to direct them to the OWC but because the internal shows up first by default, sometimes I rush import without changing it to the OWC, hence filling up my internal.
Basically what I really want to do is store everything directly to the eHD and I am not sure how to do it. Is there anyone that can walk me through the process in simple, simple terms? Although I feel I've come a long way in 2 years I still consider myself a novice.
Yes, I have read many posts, threads, discussions but with different suggestions so not sure what is right. I am not familiar with this stuff such so I end up being afraid to "try" any of it for fear of losing my pics, movies forever. Or having to re-do them somehow. I read about just moving iMovie but too many options as to how and not sure which is right. Most forums are for people who know more than I about this already and suggest things like change events to view by volume (did it) but then I read stuff like open volume where events are stored and drag to volume you want to store it. Well for someone like me that raises more questions than answers. What volume? Do they mean in my case drag to the eHD? Will this keep everything the same as I had it? Will I still have my dates? Titles? Some discussions say copy. Do they mean move? Etc. Etc. Etc.
Really I want to just store directly to eHD for primary. I want to be able to open iMovie, iPhoto and have everything just like I do now but with all that glorius 1TB storage. I don't want to redo anything---just move and run off the eHD. Possible? If I simply unplug my eHD and reconnect---will I get the option I did 2 years ago to store directly to the eHD?
UGH!

Hi BDAqua,
If it's "easy" I would consider getting another 1 to 2 GB.
I read a post before I posted here that referred me to Ken Stone's site about formatting and partitioning but I couldn't change the "Volume Scheme" like in his examples. My real ones were greyed out so I didn't have the option to select. And honestly--reading on it's pretty complicated (based on my lack of knowledge with this) and I'm afraid I would screw it up anyhow. Anything else besides partitioning?
Anyone know what happens if I just turn-off Time Machine? What if I unplug the eHD and plug back in and start over? Like a re-boot of sorts? Too good to be true?

Time Machine External Hard Drive (primary storage and backup)

Hi all, Recently purchased a 500G Mac Mini as a dedicated HTPC and have a question regarding Time Machine (I didn't see a dedicated forum page for TM). I have 2 1.5TB external hard drives (Free Agent for Mac). One houses all my iTunes and Movie files (connected to the Minin via FireWire 800), the other is for back-up of the first drive (connected to the Mini via USB). Can Time Machine be used for automatic back-ups from drive 1 to drive 2? Also, Time Machine also back up the Mini's 500G internal HD (assuming there is space/I don't max out the primary 1.5TB drive) as well as the primary external HD (in other words, back up from 2 sources)? Are there any special settings I need to apply for this set-up?

Hello! From my playings around with Time Machine I do not think you can program it to backup 1 external drive to another. Its main purpose is to backup your internal hard drive to an external source. Be careful however because it makes hourly, daily, weekly and i think monthly backups of different sizes, so after a while, if you take something off your computer and forget it, you could loose it. That said, you can drag and drop from one drive to another and still use time machine. For example 'backup' external drive 1 to drive 2, then use drive 2 as a time machine. You just wont have as much room, and time machine will not mess with whatever folders you drag and drop because its not apart of the time machine 'folder'. Hope this helps a bit.

ZFS server as primary storage for Mac/Windows?

I want to use ZFS for most of my storage, accessible from Mac / Windows / Solaris / Linux / etc. Basically replacing most local SATA / USB / IDE drives with an array of SATA drives on a ZFS server. Low-latency is important.
Is this reasonable / possible?
I currently have gigabit ethernet, but am afraid the performance would be too low. I'm hoping to improve the interconnect using an existing PCI Express x1 slot for the Windows machine, as all the other slots are full, but haven't found any likely-looking cards.
Yes, I'm a newbie to such things. Use small words.

While possible, the issue resides with solaris itself, not ZFS. ZFS is easy to use and learn. In a few hours you can master it...
But if you want to network it to be accessible by windows you need to set up samba on solaris so that it can be accessed by windows... well on a scale of 1-10 the difficulty is 70.
Oh, and don't forget setting up permissions...
Difficulty level:
Solaris = 70/10
Linux = 10/10
Windows = 1/10
Now if you have a couple of weeks to dedicate then go for it. But I wouldn't go in expecting to "learn it on the weekend". Not even a 10 hours a day spent learning it weekend. Learn solaris first, THEN buy the hardware and build a server (if you get to that point).

Connectivity between UCS 6249 - UCS 6248 Switches and 10GB iscsi on EMC Storage - VNXe 3200

Hi
I am trying to check VNXe 3200 Connectivity with SFP+ ( Cisco UCS 6249 - UCS 6248 Switches )
will the 10 GB iscsi fiber / Copper connect directly to the UCS 6248 and what is the type of Cables ?
will SFP and SFP+ connect to each other or that will cause some issues?
i tried to search the EMC side but getting difficulty to get the Document showing the Comparability but expecting soon so wanted to check from Cisco side
I know this is the Guide to refer to
http://www.cisco.com/c/en/us/products/collateral/servers-unified-computing/ucs-6200-series-fabric-interconnects/data_sheet_c78-675245.pdf
but please help me finding answers
Thanks

Hi Sami
https://community.emc.com/message/841141#841141
has the answer
EMC does not support Passive Twinaxial cables in an iSCSI or FCOE environment.
EMC only supports Active Twinaxial cables in an iSCSI or FCOE environment.
We currently support EMC, Brocade and Cisco cables.
SFP-H10GB-ACU7M and SFP-H10GB-ACU10M are active twinax cables
see http://www.cisco.com/c/en/us/td/docs/interfaces_modules/transceiver_modules/compatibility/matrix/10GE_Tx_Matrix.html

Using iPod as primary storage for all music, help!

Hello all!
Okay, so I bought a 60Gb 5G iPod last month and I'm loving it. However, I'm using it a little differently than most and because of this I'm unable to use many of the conventinal "cures" people have suggested. Here's my situation.
Rather than having my music stored on my computer and then syncing with my iPod I actually store all of my music on my iPod so I can take it back and forth to work with me and play all of my music on my work computer and my home computer. Everything has been going just fine but I've run into a problem with album artwork and the traditional fixes aren't an option.
The problem is that artwork that I've added directly to the iPod isn't showing up on the iPod when I play it when it isn't attached to a computer. I know this is because artwork needs to be added to iTunes and THEN transferred to the iPod.
So, how does someone like myself who isn't managing through music on their computer's hard drive go about correcting such a problem? I don't want to dump everything off of the iPod and back onto my computer, just takes way too long. Can this problem be solved by accessing the iPod DIRECTLY through iTunes?
Thanks!
5G iPod Video Mac OS X (10.4.2)

You're welcome.
Although you haven't seen many reports of iPod hard drive failure, it can and does occur as it can with any hard drive.
Maintaining a regular backup of all important data is very important if not the most important. It isn't a matter of if but when a hard drive has a partial or complete failure since none last forever.
I learned this painful lesson the hard way. Without warning, I experienced a complete hard drive failure on a G3 PowerBook less than one year old and the only time I've experienced this but it only takes once. Apple replaced the hard drive under the standard 1-yr warranty period but none of the existing data was recoverable. I didn't maintain a backup at the time and I lost everything.
Currently I use a 3rd party backup utility called SuperDuper! which creates a complete bootable clone backup of my hard drive saved to a Firewire drive. It includes a Smart Update feature which updates files that have changed only between backups.
I never want to go thru that painful experience again so I emphasize maintaining a backup when I see an opportunity to do so. Always better to be safe than sorry.

Configure iSCSI multipath in OVM 3.1.1 with storage plug-in not possible ?

I have a configuration with 4 iSCSI paths to storage system. All is working fine if the discover and login
process was performed manual. Multipath is working well with 4 paths.

I want to configure iSCSI multipath in OVM manager using specific storage plug-in.
I proceed “Discover SAN Server” with following parameter:
Name: Storage-Name
Storage Type: iSCSI Storage Server
Storage Plug-in: Fujitsu ETERNUS
Admin Host: IP-Addr. of storage system
Admin Username: user name to access storage system
Admin Password: password
Access Host (IP) Address: 192.168.10.1
After this configuration I see my storage system and assigned physical volumes to an access group.
Now the volumes are available on the OVM storage server, >>>> but I lost the multipath functionality <<<<<.
# multipath -ll

`-+- policy='round-robin 0' prio=50 status=active
`- 33:0:0:1 sdd 8:48 active ready running
The reason for this behavior is that only one Access Host (IP) Address can be specified.
With this IP address a session was established … but only 1 session and not 4 !!
How can I specify the remaining 3 paths to have proper multipath functionality?
I know that Citrix XenServer accepts more Access Host (IP) Addresses,
e.g. 192.168.10.1,192.168.10.2,192.168.20.1,192.168.20.2
Thanks for help.

@user12273962
Yes, you are right. The storage plug-in is for management of the storage within OVM.
This is working well, but I'm still missing the multipath fuctionality. This storage plug-in is not responisble
for establish the multipath, but OVM should take care of this.
@budachst
Yes, OVM did only open one session and loggin only to one target, because only one Access Host (IP) Address: 192.168.10.1
can be specified.
# iscsiadm -m session
tcp: [21] 192.168.10.1:3260,25 iqn.2000-09.com.fujitsu:storage-system.eternus-dx400:CM0CA3P0
In my point of view it is not possible to configure the remaining targets, so this is a design problem.
Any new inputs and informations are welcome.

MacBook Air as Primary Computer: Offline Storage Options

Today I have my MacBook Air configured (via MobileMe) to store/access files on my Mac Pro. This works very well. In particular, I can pull Aperture Libraries and work with them on my Air, and can also access all of my iTunes content stored on my Pro through Home Sharing (i.e., copying only what I want to my Air when needed). Finally, I can print to the printer hooked to the Pro with Printer Sharing.
I need to separate my files from my Pro. One option is to buy another Mac (e.g., a Mac Mini, for example) and replicate the same network/file management process as I have now with my Pro.
However, I wondered if there is another option -- could I instead use a Time Capsule and a powered USB hub to fulfill my offline storage and network printing needs, without purchasing a new Mac. Specifically, I was considering: (a) a 1TB Time Capsule, using the Time Capsule drive as my primary storage drive for Aperture libraries and media, (b) a powered USB hub connected to the Air Disk USB port, (c) a separate 2TB USB drive for Time Machine (for both my MacBook Air and my primary Time Capsule drive) hooked to this powered USB hub, and (d) a USB printer also hooked to the powered USB hub.
I am reasonably sure I can get this working for my Aperture library as well as for other offline files, but an not sure about iTunes. I do not know how I would split-up my iTunes Library to function in a similar fashion as today (e.g., my library sits on my Pro and I only copy what I want to my Air for remote purposes). Finally, not sure about the performance of opening my iTunes library from my Air to this network drive if, for example, I wanted to use AirTunes to stream to my Apple TV.
I searched but did not find anyone looking to do something similar. Any advice, insight or considerations would be appreciated.
Thanks!

Just to share my growing understanding of the situation in case it might provide useful information to others.....
Once again, to summarize, my interest was to explore the potential of using the MBA as my 'only' computer. The major problem was to find a way to address the MBA's relatively small hard drive. The primary concept: find a way to keep my master files (e.g., Aperture and iTunes, other files) on a separate drive, copying only what I wanted to the MBA as required. Further, for convenience, I wanted to find a way to network this separate drive vs. attaching it via USB when at home. Finally, I desired also to establish a means of accessing this separate drive when away from my home network.
An AirPort Disk (via an AirPort Extreme or Time Capsule) provides a solution to this challenge-- with some limitations. What it CAN do is serve as offline storage for many applications/needs which extend to professional applications like Aperture. Moving albums, photo files, etc. is fairly straight-forward, even on network drives. Thus, if you have a MBA with limited hard drive space, you can copy only those things you need to the MBA's internal drive while maintaining the master library(s) on the networked drive (at least that is what I've gathered to this point).
Meeting needs with iTunes is a bit trickier. The challenge is to find a way to maintain a large 'master library' on the networked drive (e.g., the AirPort Disk or Time Capsule) and only copy what is needed to the MBA's local iTunes library. The specific limitation relates to an inability to open more than one iTunes library at a time on a single machine. Note that this is not a problem if you have two Macs on the same network - but it is a challenge with only one Mac. However, I found (at least) one third-party solution that appears to have functionality that overcomes this challenge (e.g., the application permits a user to open more than one iTunes library and manage content). So there appears to be a solution for iTunes!
HOWEVER, under this 'AirPort Disk as my Master Storage' scenario, I could not find a way to preserve Time Machine functionality for what would, in essence, be my primary disk. Time Machine is an application that runs on a single Mac. Under my scenario, this translates to one instance of Time Machine running on my MBA. I could not find a way to configure Time Machine to back up the external 'master' AirPort Disk - Time Machine only permits backups of internal hard drives and drives directly attached to a Mac. Although a number of third-party 'backup' utilities are available for networked drives, they do not appear to function as seamlessly as Time Machine. This is a show-stopper for me. If I regard the external AirPort Disk as my primary storage, I want this disk to be 'Time Machined' in the same seamless manner as my internal hard drive.
Bottom line -- IMO many users will face challenges using an MBA as their 'only' computer, presuming they want to preserve the full functionality of OSX (e.g., Time Machine). My current plan is to purchase a Mac Mini as a server. I will use the drive in the Mini as my 'master' drive, leveraging 'Back to My Mac' and 'Home Sharing' to pull content to my MBA as required -- with Time Machine working separately on my MBA and Mini.

ISCSI as shared media storage?

I was wondering if anybody here had some thoughts on using iSCSI as shared storage for media.
I would be using it via ethernet on my ready nas pro with two Gbit connections teamed to one IP.
I know of the obvious limitations in bandwith over ethernet and I know of the corruption data risk when sharing, but I will only use the same media on one PC at a time, so I guess it will not be that much of a problem.
Any other recommendations on the idea of shared storage would be very muc appreciated too.
Thanks. :)
Ulf

Thanks Eric - just want to make sure:
I have connected to the same iSCSI volume on my NAS via the iSCSI initiator in the controll pannel on both machines.
On the first machine I had to partition the volume and format it. On the second machine the drive would just turn up, as there already was a volume present.
It was like mounting a new haddrive in the firstvPC, partion and format it and then "connect" it to thecother PC too.
This would be correct, right?
Thanks Eric - apreciate your help on this one :)

Macbook air running out of storage

I am relatively new to the mac world. I have a macbook air 128g and am running out of storage space. I am wondering if I can use icloud as a primary storage for my media files (Photos, music, video, etc). Then I could potentially remove from hard drive to free up space. I am concerned if this is possible and what the cons would be. I am thinking that Itunes library and photos would not be as quickly accesible as it would be using the hard drive. Please help...

Welcome to the Apple Community.
iCloud can't be used for storage in that way. I believe sugarsync allows you to keep files online without having to have them on your hard drive.
A slightly fuller explanation here, you can keep files without having them on your hard drive by using SugarSync's 'Web Archive' Storing them in any other SugarSync location will cause them to be synchronized with your computer, a bad thing if you want to delete them from the the local storage.

External Hard Drives & Online Storage for Photographers

I would like to purchase new external hard drives and am also looking into online storage websites. I am wondering if some external hard drives are better than others when it comes to storing photos. And would also like recommendation for online storage.
Are there certain photo saving "rituals" or systems that you would recommend for keeping your photos safe and backed up.
Lastly, please recommend your favorite portable external hard drives when you are mobile.
Thank you

I have two 4TB Drobo's that are my primary storage of my digital files. My Aperture libraries reside on my Alu iMac internal drive (more on this later). My 2008 Aperture library contains about 35,000 images, all referenced to image files stored on a 2nd Gen Drobo. I don't think it is the fastest solution out there, and surprisingly it seems slower than a USB 2.0 transfer. Having said that, when I am actively working in Aperture on a project, I rarely notice a delay. From this I have concluded that I am very slow or at least the speed of the 2nd Gen Drobo keeps up with me.
As a bit of warning on Drobo. In December, I was keeping my library on the Drobo and it was taking forever to open (5-20 minutes) and eventually the library became corrupted. I rebuilt it and a few days later it become corrupted again. This is the only time I have ever had problems with my libraries. After the second time, I repaired the library and moved it to my internal drive and it has been fine ever since. Also, I noticed that on occasion Aperture would tell me that an image was an unsupported format and NO program would open the RAW file. If I replaced the RAW file from a back up copy, then Aperture was fine and could open the file. I also noticed that there would be stretches of files (5-20) sequentially named, that became corrupted so no program could open them. ( I was operating the Drobo's with Firmware 1.2.2, I think. After considerable discussion with Drobo I upgraded the Firmware to 1.3 and they also replaced the offending case with a new one. After the upgrade to 1.3, I have not had any new events of corruption since upgrading to 1.3. I could readily copy the corrupted file to another drive without evidence that the file was sick.
But contained in this story is an interesting puzzle. Historically, I was managing backup of my image files by using SuperDuper copying from one WD 2 TB drive to another WD 2 TB drive. In this scenario, the corrupted files would have been copied and my image files effected would have been lost forever. I really don't know how the vault would work in this situation.
With this thought, I have changed my strategy for backup. I work on the project with the image files residing on the Drobo. Once done, I export the pictures usually to a JPEG format for the client. IF the initial RAW is corrupted, I am warned as to which files could not be exported. If everything goes fine, then I know my primary image files are ok. I then export the project to an another external drive (I all it xxxxxx ARCHIVE) where I keep a separate library and I then import the project into that ARCHIVE library; Once imported I relocate my masters out of the library into my finder based folder system.
I also generate a temporary project file as soon as I import into Aperture and store that temporary project file on my ARCHIVE drive.
Hope this provides some insight.
Regard, steven

Movie Storage using AppleTV

I am thinking about an ATV or actually two of them (one in the theater and one in the family room). I have a couple of questions. First a little background, I have an Imac and macbook with a Time Capsule I use just for backing up the computers. I have ethernet at both the locations I am interested in putting an ATV.
First questions is simple, can I have two ATV's on the same network?
Second, while I am probably not interested in ripping old stuff, if I start buying movies via Itunes, I would like to store them on another external hard drive and be able to access to both ATV's, is this practical? I guess I ask about external hard drives because I assume I will eventually fill up the ATV's.
Third, can one ATV access a movie on another ATV?
Finally, I am not interested in a real elaborate setup just something easy to use. Will ATV meet that objective?
Thanks in advance

the appletv cannot (and should not) be used as a primary storage device. it should only ever have copied of your media (not the only copy). anything you purchase on the appletv will auto sync back to your primary itunes library.
Third, can one ATV access a movie on another ATV?
no, appletv can only take stored content from your itunes library on a pc/mac.
Finally, I am not interested in a real elaborate setup just something easy to use. Will ATV meet that objective?
i'm sure it will assuming that you don't try to use it for something it wasn't designed to be.. ie a storage device or media server. the appletv is a client device and should be looked at as an ipod your tv.

Campus cluster with storage replication

Hi all..
we are planning to implement a campus cluster with storage replication over a distance of 4km using remote mirror feature of sun storagetek 6140.
Primary storage ( the one where quorum resides ) and replicated secondary storage will be in separate sites interconnected with dedicated single mode fiber.
The nodes of the cluster will be using primary storage and the data from primary will be replicated to the second storage using remote mirror.
Now in case the primary storage failed completely how the cluster can continue operation with the second storage? what is the procedure ? how does the initial configuration look like?
Regards..

Hi,
a high level overview with a list of restrictions can be found here:
http://docs.sun.com/app/docs/doc/819-2971/6n57mi28m?q=TrueCopy&a=view
More details how to set this up can be found at:
http://docs.sun.com/app/docs/doc/819-2971/6n57mi28r?a=view
The basic setup would be to have 2 nodes, 2 storageboxes, TrueCopy between the 2 boxes but no crosscabling. The HAStoragePlus resource being part of a service resource group would use a device that had been "cldevice replicate"ed by the administrator. so that the "same" device could be used on both nodes.
I am not sure how a failover is triggered if the primary storage box failed. But due to the "replication" mentioned above, SC knows how to reconfigure the replication in the case of a failover.
Unfortunately, due to lack of HDS storage in my own lab, I was not able to test this setup; so this is all theory.
Regards
Hartmut
PS: Keep in mind, that the only replication technology integrated into SC today is HDS TrueCopy. If you're thinking of doing manual failovers anyway, you could have a look at the Sun Cluster Geographic Edition which is more a disaster recovery like configuration that combines 2 or more clusters and is able to failover resource groups including replication; this product already supports more replication technologies and will even more in the future. Have a look at http://docsview.sfbay.sun.com/app/docs/coll/1191.3

File storage question.

Hey all,

Wherever you save the project when you first start it, that's where it will be. Start each project on an external drive.

My M-Air start up disk if full; I have the a new time capsule, how do I transfer and use the TC as my main storage drive?

The start-up disk on my MAC AIR is full - I just added a new Time Capsule - how do you transfer your files from the AIR to the TC and set it up to be used as my primary storage disk - not my Mac Air

Get a second external drive, drag both the iTunes library and the pictures to it, launch iTunes with the Option key held down, and point it to that instance of the library. This also works with iPhoto, but see below.
A drive or partition needs to be formatted as Mac OS Extended in order to hold an iPhoto library or for Time Machine to back it up.
