RAID: What is it and what are the benefits and How to Setup?

I was wondering what RAID is? How do you set it up? And what are the benefits of having dual hard drives setup in RAID?
I have a powermac G5 (quad 2.5ghz/16gb RAM/80gb SSD & 1tb HD) and I want to setup my SSD and HD in RAID...would that be wise? Thanks guys!

Hi-
One of the best ways to reduce a RAIDs performance is to mix drives.
Mixing dissimilar drive types should be a shortcut to disaster.
I would rethink the drives to use for a RAID.
The most reliable RAID will be from RAID certified hard drives of the same make and capacity.
After that, you get into software RAID vs Hardware RAID, which both have drawbacks, the latter being price due to the required controller cards and external housing needed for all the drives.
Hardware RAID will allow for better performance, and allow for use of a RAID 5 or RAID 6 to build in redundancy to protect in case of a drive failure within the set, without losing the entire set.
A SSD RAID can really offer some blistering speeds.
I think possibly a bit much for a G5.
With software RAID, a two drive RAID 0 as scratch for video or graphics work can greatly increase render performance of those respective softwares.
A two drive boot RAID 0 with 2 WD Velociraptors can increase OS X responsiveness.
All two drive RAIDs suffer from the need for a robust backup, making a third and fourth drive needed to create a RAID 0+1.

DNFS and ZFS Storage Appliance: What are the benefits and drawbacks

Hello All:
I have a client who has a 4TB database and wants to easily make clones for their DEV environment. The conventional methods (RMAN duplicate) are taking too long because of the size of the db. Looking into dNFS as an alternative standalone and looking into the ZFS storage appliance as well. What are the benefits of just dNFS being configured alone? I'm sure you can clone easily based on the copy-on-write capabilities but weighing the dNFS option alone (no additional costs) vs using ZFS Storage Appliance (which used dNFS as its protocol) but costs money. Your thoughts?

Dear Kirkladb,
as far as I understand your question you like to know the road blocks for usage of dNFS in combination with a ZFS Storage Appliance.
First I like to mention that dNFS is no feature on the appliance and the dNFS traffic is perceived as regular NFS traffic, so there is currently no feature which needs extra licenses on the ZFS Storage Appliance if you run dNFS on your client; dNFS is client driven and requires software on the client. Second the use of dNFS does not exclude to have snapshots or clones on the appliance, although cloning requires a license to be bought.
As mentioned by Nitin the appliance offers many features, some are based on ZFS, some are coming for the underlying OS and some coming form additional software. You seem to be interested in NFS, this is I guess mainly related to NFSv3 and NFSv4. The appliance will see dNFS from the clients as regular incoming NFS requests, means client side makes the difference and therefore it is important to have dNFS and maybe Infiniband drivers at a current level.
To get a copy of your production Database you could go different ways, the appliance offers to create a snapshot (free of charge) which is read-only and to create a clone (additional costs) on top of the snapshot. You have mentioned RMAN, as additional method, Snap Management Utility (Clone License) will also help here and maybe DataGuard. I am sure there are some additional ways not listed.
The point I wanted to make is that Cloning on ZFS-SA abd NFS are different are topics.
Best Regards
Peter

You pay as part of your cellular/telephone bill unless you use Wi-Fi which is free.

HT204053 What are the pros and cons of 1) choosing to use the SAME Apple ID for iCloud services on one side, and purchases on the iTunes Store, App Store, and iBookstore, on the other side; or 2) to have and use two separate Apple Ids for these "two sides

All is in the title, so I repeat it below with a better identation.
What are the pros and cons of
1) choosing to use the SAME
Apple ID for iCloud services on one side, and
purchases on the iTunes Store, App Store, and iBookstore, on the other side; or
2) to have and use two separate Apple Ids for these "two sides"?
P.S.
I have loads and loads of free podcasts in iTunes in my iMac, that are certainly more thant the 5 gigas the iCloud provides for free, so I don't want those to go to the cloud. But this is perhaps a different question...
Also need to mention that I have itunes on a mac, a pc and an iphone.
Sorry to look so silly with this question, but I don't get the "big picture".

You need to create a user account for your wife (or yourself depending on who has the current user account). When syncing, each of you should sign in as a separate user, login to iTunes and then sync. I had this problem when my sister got an iPhone. When we did her initial sync, everything on my iPhone showed up on hers. Apple gave me this solution.

I have a new computer and I want to make it my home device for I tunes. I have home sharing, and all of the music and files are on the new computer. Now what do I do to make the new computer the home computer for Itunes?

I have a new computer and I want to make it my home device for I tunes. I have home sharing, and all of the music and files are on the new computer. Now what do I do to make the new computer the home computer for Itunes?

The computer (windows platform) where I initially began using Itunes has four other computers/devices that are shared with it. All four of the other computers show up in my account, and can be managed. Or I can remove them. But on the new computer that I want to be my base computer (home if you will). The computer I want it to replace, when ITunes is open, has a tool bar, with various functions. All of the other devices are linked to that computer in ITunes, under Home SHaring. The new computer, shows the downloads via Home Sharing, but it does not show/have any tool bar.
I want to activate the new computer to be the computer via ITunes where all of the devices are linked to it as the base for ITunes. And, I don't know how to make that happen.
I hope that makes sense.

What are the pros and cons of installing java+abap stack for portal?

Hi all,
1.What are the pros and cons of installing java+abap stack for portal?
2.what effect it does on the ume options to be choosen??
3.for the purpose of integration of r3,bw and crm on portal and crm 4.0 60.2.3 business package which option of stack(java or abap or both)will be good option and which ume option while installation should be choosen?
regards
Rajendra

Hi Rajendra,
The NetWeaver Installation Master Guide offers some good scenarios on the pros and cons:
https://websmp201.sapag.de/~sapidb/011000358700005412792005E.pdf
In a nutshell:
ABAP+JAVA
Pros
- Decrease # of servers required to administer the portal
- Less costly
Cons
- Upgrades could be dependent on ABAP and Java release level
- Additional load on the server due to ABAP stack
- Limited scalability
JAVA and ABAP on separate server
Pros
- Improved performance
- Allows each system to be single-use purpose therefore downtime does not affect other components
- More scalable
Cons
- Adds complexity to landscape
- Additional costs

What are the cause and fix for the following error message? NS_ERROR_FILE_ACCESS_DENIED failure code: 0x80520015

Every time I close my Firefox browser I receive the following error message (see details below).
FYI:
-- I am running the current version of Firefox.
-- I had no problems with this error message until my computer was recently attacked by 2 viruses:
` SystemFix
` Win7 Antivirus 2012
Both viruses have since been cleaned from my computer. However, I am still receiving this error message.
Here are my questions:
* What are the cause and fix for this problem?
* Do I need to uninstall and reinstall Firefox?
* Is it possible that this error message is related to an add-on and that it has nothing to do with the recent virus attacks?
I look forward to any feedback and support you might be able to provide.

What are the advanteges and disadvanteges of using pl/sql over hibernate

i knwo that pl/sql are well structure and provide a lot of functionalities with oracle databse , but my question is the hibernate might give some advnateges of scalability over pl/sql.
so what are the advanteges and disadvanteges of using pl/sql over hibernate?
and does oracle recommend using hibernate for connecting JSP with oracle 11i , or it is better to connect the JSP pages with oracle databse using pl/sql ?

812643 wrote:
but if i search for the diferencess then there are a lot of opinions about this ..., specially when they say that with hibernate you can integrate with any DB , and it provides object printed architecture, etc.All databases are not equal. This is a basic and fundamental fact. SQL-Server is not Oracle. Oracle is not SQL-Server. As it is the case with Sybase, Ingres, DB2 and other database products. They are all different. And there are some very core differences between them.
So how would a product like Hibernate treat these database products with their differences? By using the lowest common denominator. Which means your expensive database product is dumbed down - and even MS Access will likely have better and more features.
You also need to decide what is the "permanent" part in your architecture. What is going to the core? What is the expensive part? The app server (with Hibernate)? Or the database server?
What are you likely to change next year? The app server server? Or the database server?
In the vast majority of cases, the core is the database server. That is your biggest expense and investment. As it should be - as it holds that which is most precious to business, data. You want to ensure the integrity of that data. The accuracy of that data. Make sure that it can be easily backed up and recovered. Is flexible to use. Etc. Etc.
The database server is the core - and that is where you need to realise your return on investment. By using the database server to its full extent.
Hibernate does not do that. And in that respect, it is junk.
Why does it not do that? Because many Java developers are totally and fully clueless about what database servers are and how to use them. And want to use them as little plug-in black boxes - bit buckets that are only there to provide a data persistence layer. Instead of using the database server to its full extent, they instead use Hibernate, and try to do their own "+database thing+" in the app layer - and do it poorly and with utter lack of any scalability. (and no, only ignorant Java heads think that scalability means throwing more money and h/w at it)
My largest database processes billions of rows per day, every day, 356 days a year (between 350 to 450 million new inserts into a single table per day). And have been for several years now. It does so using PL/SQL. Using Oracle to its full extent. Then there are Java heads that cannot even design and code an app that effectively process 1% of this volume... and grasp at straws like Hibernate and other Java cr@p to "fix" this - when the actual problem is their total lack of ignorance in how to use and scale the database server.
Hibernate is trash - and a symptom of Java developers's ignorance of database technology.

What are the pros and cons re using an intel iMac vs MacPro with LP8?

I'm considering getting a new intel Mac in the near future (presuming a new MacPro will be released in the near future - maybe at the same time as Leopard). I compose largely for film and television and I am composing largely using a combination of loops, software instruments and some recorded live performance. I usually sync to a low res quicktime movie.
I do like the idea of a simple and uncluttered work environment with an iMac, added to which there's also a degree of portability with the iMac however the MacPro is obviously more powerful. I'm not sure how much the difference in power between the two computers would affect me.
Would I be compromising myself much if I went for the iMac over the MacPro? What are the pros and cons of the iMac vs the MacPro in relation to Logic Pro 8?

In the world large-scale music composition using samples, loops, etc (especially for film) your two biggest needs are RAM and HD speed/access. The imac looses big time in this department (as a single computer at least) as it can only be upgraded to 4gb ram, and only holds one internal HD, and also lacks any PCI expansion for DSP cards, audio interfaces, etc.
In generalyou want to separate your data vs applications as much as possible, to ensure both can be accessed quickly and easily by the computer. So its best to have your system software / applications on one internal HD, and your logic data (samples, audio recordings, loops) on another drive(s). You can do this with an iMac via USB, FW800, & FW400, but depending on how big your projects get, how many USB and FW drives / interfaces you use, and how much data you need to stream, you could overload the buss on the imac (not sure if it has multiple busses or not). Plus speed wise, internal SATA are much faster than external drives, and the mac pro with its 4 internal slots seems like a great choice for speed and flexibility.
However, if you dont find yourself doing large scale projects, then you might be better off going with an imac. We just purchased one for my father and it runs great! It blows the socks off of my Dual 2.5 G5 tower in terms of CPU speed! If you run into problems running things from the imac, you could always add a mac-mini down the road to stream sample libs, as a Logic node, etc, which seems to be a much more cost effective solution.
I hope this was helpful, but I probably just made the decision harder . In fact, if I were to start over today, I dont know if I'd go with a MacPro, or an iMac / mac mini combination. they both seem to have their advantages / disadvantages.
Best of luck!

Optical drive on iMac at work, barely one year old, won't read CD's....disc utilities shows disc unavailable! Rarely used and out of warranty, what a rip off!! I have been on MACS since the 80's and things are getting more and more difficult

Optical drive on iMac at work, barely one year old, won't read CD's....disc utilities shows disc unavailable! Rarely used and out of warranty, what a rip off!! I have been on MACS since the 80's and things are getting more and more difficult to deal with. Why did it quit after barely being used? Any help from Apple?

It depends on what you mean by "barely one year old". If the iMac is only a couple of days out of warranty, Apple's been known to make exceptions and extend the warranty, though it's by no means guaranteed. If it's several days or more out of warranty, then Apple will fix it, if it's a hardware problem, but the repair won't be free. This is no different now then it would have been with a Mac purchased back in the 80s.
Why the drive failed, if indeed it has, is impossible to say. Could have been a static shock, a weak component that failed when power was applied, or a mechanical fault in one of the tiny parts used in optical drives and hard drives that finally broke.
