Which one raid level is better

Hi:
We have an 3310 raid configured like raid1 with one logical drive,
with 10 disks (5 mirror) and 2 for spare.
In last 6 months we had 5 fatal fails, first time we changed the controller,
second time, we changed the chassis, however it did not fix the problem.
Data was lost in each fatal fail.
is it normal?
maybe, another raid level will fix our problem?
Our system is redundant, has 5 servers-prime and 5 servers-backup
When one prime fails, the backup takes the control.
Only, raid 3310 is not redundant.
Which one will be an better configuration?
is it possible to have 3310 redundant?
thanks

Hi cmadero33
Did the Sun engineers upgrade the firmware on the 3310 when they replaced all the disk's and controllers for you ?
I'm assuming this array is in a data-center/server room with good cooling etc (ie it's not cooking itself)

Adobe Cloud has 2 different Muse programs.... how do I know which one is the newer better version?

So I am new to Muse, and my Adobe Cloud has 2 different programs from Muse... how do I know which one is the newer better version?
One Must program (Muse CC 2014.2) has a black background when working on it... it looks like other Adobe programs such as Photoshop.
The other one is light color (Muse CC) very similar to the black color Muse on functions.....
One of the difference I notice is that the light color Muse has a few widgets in the library, while the black background Muse seems to have an empty library
So... why are there 2 different Muse programs in my Adobe Cloud?

Hi
The latest version of Muse is 2014.2, so you need to uninstall another version of Muse manually.
regarding the items in Library, you can add items in your library manually, as shown in this article
Adobe Muse Help | Organizing and reusing design elements using Library panel
Please let me know if you have any other query.

Which one you think is better?

theyre all in same price range, i just want to know which one would be better for my pc. now planning on o/c a lot since theyre fast already.

Honestly it's less about the vendor(GSkill, OCZ, Corsair, Buffalo, etc) and more about the manufacture of the IC itself.
DDR2 has had the original Micron fatbodies, some Elpida chips, and then the more common Micron D9 as the high end RAM to own. When you research RAM this is just as important to keep in mind as manufacture/warranty/reputation.
Case in point, while remote it is possible that if you bought a set of the OCZ, the Crucials, and the Corsair all metioned by everyone they could possibly all be Micron D9GMH chips under the hood, all from the same lot of wafers in the fab. Then it doesn't really matter what manufacture you buy from the will probably clock/overclock about the same, and perform about the same if it's a quality vendor.
If you aren't overclocking I say get the cheapest that meet you specs. (just say 5-5-5 at 500Mhz) . Of course if you are wanting serious overclock it is necessary to follow some forums and look for vendors binning a good batch of IC's that have been yielding well and buy at the time. While not common a vendor can have a good batch get great reviews and you buy 4 months later and it's get different IC or a different binning proceedure and not get what you are thinking.

Which one of these options are better for CDS updation?

Hi,
I was going through the data flow in the outbound direction in NW mobile.
the data object instances in the CDS are updated by 3 means:
1) DOE triggered
2) backend triggered
3) backend pushes instance to DOE.
which one of these is better.
kindly explain the reason as well.

Hi,
Actually there are only two types of Synchronization types between Backend & DOE,
1. DOE Triggered
2. Backend Triggered
DOE triggered adapters will pull the data from Backend to DOE where as Backend triggered adapters will push the data from Backend to DOE (there are two types in BE triggered, Key push & Instance push).
Backend triggered sync type is always better since the changes have been pushed to the DOE then & there (this can be achieved by event,etc..). So that always DOE & Backend will be consistent & the receivers (devices) will also get the latest data in order to proceed with their day to day activities (i.e. business critical data).

Ananth.

RAID level

Hi,
I'm building a three node RAC OLTP system, which RAID level is better for performance? Is there any document available?
Thanks,
GK

Depends on your application. If there was always one right answer there would be only one flavor of RAID.
The general rule for Oracle is to do what ASM does: SAME
Stripe And Mirror Everything.

Advice on RAID Sets, Volume Sets, and RAID Levels of the Volume Sets using an Areca Controller

I have read through a lot of information on disk usage, storage rules for an editing rig, users inquiries/member responses in this forum and I thank each and every one of you – especially Harm.
In building my new workstation, I purchased five (5) WD 1T, 7k, 64M SATAIII hard drives and an Areca RAID card, ARC-1880ix-16-4G, which I plan to use primarily as my media/data disk array. The workstation will use a 128GB SATAIII SSD as the OS/program drive and I will transfer two (2) WD Raptor/10k SATA 70GB drives from my current system for pagefile/scratch/render use. I tentatively plan on using a mobo SATAIII port for the SSD and mobo SATA ports with a software RAID (level 0) for the 10k Raptors.
In reading the Areca Instruction manual, I am now considering exactly how I should configure the 5 physical 1TB drives in terms of RAID Level(s), Volume Sets, and RAID Sets. I must admit that I like the opportunity of allowing for a Dedicated Hot Spare as I am generally distrustful of the MTBF data that drive vendors tout and have the bad experience in the past of losing data from a mal-configured RAID array and a single drive hardware failure (admittedly, my fault!).
In line with the logic that one doesn’t want to perform disk reading while trying to write at the same time (or vice-versa), I am thinking the approach above should work OK in using the mobo disk interface and both software and external hardware RAID controllers without having to create separate RAID level configurations within a Volume Set or further dividing up the physical drives into separate RAID sets. I know in forum messages that Harm noted that he had 17 drives and I could envision a benefit to having separate RAID sets in that situation, but I am not at that point yet.
To some degree I think it might be best to just create one RAID Level on one Volume Set on one RAID Set, but want to solicit thoughts from veteran controller users on their workflows/thoughts in these regards.
Anyone care to share thoughts/perspectives? Thanks
Bill

Thanks for the speedy feedback Harm - I appreciate it.
I was thinking RAID level 3 as well.
Of course, it's always something! I purchased the Caviar Blacks by mistake - which are non-TLER. I will work with EggHead to return the ones I purchased and replace them with RE4 versions as I'm not thrilled about the possibility of the controller declaring the volume/disks degraded unnecessarily and although I have the DOS utility WDTLER where one is supposed to be able to enable/disable TLER on WD drives - I suspect WD is way beyond that now anyway with current builds.
I agree with you about just testing the performance of the options for the raptors - on the mobo and then on the controller. When I benchmark them I'll post the results in case others are curious.
Thanks again....off to EggHead!

[Radeon] which one? r9250 128 (128bit) or r9550 128 (64bit)

hi to all..
need advise regarding which one of this radeon better to buy. which one perfom better?
thanks.
(sorry for my englsih)

Whoops, of course it's a wrong decission!
9600SE is 64bit... but dunno if compared with 9550 64 bit.. maybe it's the same (both are 9600 core).
But 9550 128bit is pretty good, and almost all (if not all) can get to 9600 core clock, some can get to 9600pro (look at my sig, it beats some of 9600pro) and rare can get & exceed 9600xt (usually this "special" 9550 price is pretty high).
But your choice is pretty hard, 9250 128bit or 9550 64bit or 9600se... can you refund it? or pay extra money to exchange to a better card?

Which one to run windows?

I want to install windows only to play windows only games. I've heard of 3 different applications that can run windows, VM-ware, Parallels, and Bootcamp. I've heard that Parallels was having some bugs, but want to hear some opinions. Thanks.

Hi and welcome to Discussions,
for running Windows solely for playing games you best and only option is BootCamp, since it enables the native use of the hardware in your Mac.
At the moment Fusion as well as Parallels have only support for DirectX 8 with experimental support for DirectX 9.
Check the system requirements of the games you want to play.
If they need DirectX 9 to run, then use BootCamp.
If they are 'older' games which only needs DirectX 8 or lower, then either Parallels or Fusion should suffice.
Which one of them is better (less buggier) is open for discussion, so you might be better trying them for yourself with the Time-delimited Demos they offer.
regards
Stefan

6D vs 70D?? which one to buy

HI All,
I am an newbie in photography..its more of an hobby which i got into recently. I am looking to upgrade from my ancient Canon Rebel T1i to either 70D and 6D but i am totally confused which one should i go for. Other than the $700 price difference and full frame vs crop sensor i want to know which one should i go for. I shoot mainly landscape and night time photography and have a tokina wide angle and 24-105 L lens. Mainly looking for Pros and cons of either cameras and which one would work for better for me and why.
Thank you all in advance for you inputs.

If you have full frame lenses, particularly the 24-105, mostly shoot landscapes and don't intend on buying new lenses I'd say get the 6D.
The 70D is a nice camera, I have one, but without something wider you're not going to have the tools you need for landscapes.

RADEON X1650 vs nvidia GT8500. Which one to buy?

Hi,
Im planning to build a new computer. I found these two cards, but im not sure which one is better to buy. I mean, will ati open source drivers work on x1650? And how about nvidia, is its closed source driver good? The reason why i cant choose, is that i dont know which ones driver will work better. I currently have computer with radeon 9600 and ati open source driver works with no problems, but maybe nvidia drivers will work even better than ati's?
I dont play games at all, so the performance difference is not very important, i just need compiz or kwin eyecandy which would work with no lag. Also how about kde4 performance with nvidia? Mine radeon 9600 works very fast with kde4, and i saw some people who have problems with nvidia and slow kde4.
Also, i chose motherboard foxconn Foxconn A690GM2MA-RS2H and amd athlon 64 x2 6000+. Will this motherboard work with this cpu and will it be fully compatible with linux?
Thank you
EDIT: fixed the motherboard type

For now, just go with Nvidia. You won't regret it.
I've just recently switched to Nvidia from an ATI card (an X700), and after almost 2 years of suffering with poor quality of the ATI driver and waiting for the ATI open/close source driver to mature, it's really an eye opener. The quality of Nvidia driver is very, very good (especially compared to that of ATI). In short, the Nvidia card just work (and work very well) with Linux and provides additional features such as twinview or VDPAU, while with ATI you only get a "mostly" working driver (no/poor 3D support, for example), which is really sad when you see your ATI card that can play Half Life 2 on Windows just fine is struggling hard just to render Nexuiz/Google Earth because of poor driver support.
Sure, the ATI open source driver is rapidly improving, but to be honest, it wasn't quite ready yet to justify buying an ATI card right now. Just look at the news item on the problem with new kernel and ATI KMS. If I were you, I would just go with the card that have a working driver right now, instead of buying a card that required me to wait for a driver to mature in order to use full performance of the card.

Which one is better ODS-INFOCUBE for reporting in BW

Hello expert's
1.I want to know which one ODS or INFOCUBES are better (technically/functionally) for reporting purpose in BW.if some one is having any comparisons on ODS/INFOCUBE then plz pass on to me.
2.Are Z tables reliable in case of data updation and fetching when we create ODS/INFOCUBE.
3.HOW RELIABLE THE "Z"(*TABLES/REPORTS) are in SAP-BW/R/3-ABAP.

1.Cubes are optimized for reporting..due to star schema structure.Use cubes for reporting aggregated data to be accessed by large number of users.
ODS are for detailed level reporting.ODS structure is like flat DB table.
usually drilldown is setup from cube report to the ODS report.
2.Are u referring to custom ODS and cubes..then they have the Z tables internally..reliability depends on ur design.But always try to use BC content,else copy BC content and change/enhance it.else if no BC content found then create Z-content directly.
3.Again,depends on the design.But always using BC content is suggested.
cheers,
Vishvesh

Difference between Temp table and Variable table and which one is better performance wise?

Hello,
Anyone could you explain What is difference between Temp Table (#, ##) and Variable table (DECLARE @V TABLE (EMP_ID INT)) ?
Which one is recommended to use for better performance?
also Is it possible to create CLUSTER and NONCLUSTER Index on Variable table?
In my case: 1-2 days transactional data are more than 3-4 Millions. I tried using both # and table variable and found table variable is faster.
Is that Table variable using Memory or Disk space?
Thanks Shiven:) If Answer is Helpful, Please Vote

Check following link to see differences b/w TempTable & TableVariable: http://sqlwithmanoj.com/2010/05/15/temporary-tables-vs-table-variables/
TempTables & TableVariables both use memory & tempDB in similar manner, check this blog post: http://sqlwithmanoj.com/2010/07/20/table-variables-are-not-stored-in-memory-but-in-tempdb/
Performance wise if you are dealing with millions of records then TempTable is ideal, as you can create explicit indexes on top of them. But if there are less records then TableVariables are good suited.
On Tables Variable explicit index are not allowed, if you define a PK column, then a Clustered Index will be created automatically.
But it also depends upon specific scenarios you are dealing with , can you share it?

I am going to buy a macbook pro for grade 12, and I need to know wheather I should get a macbook pro or a macbook pro retina. If someone could tell me (in a very simple way) which one is,better for me and why, I would be ever so apprreciative.

Why do you need a expensive MacBook Pro?
Your attending high school and unless everyone else is rich also your likely going to be a target by the more poorer students for theft or damage to the machine.
You could keep it home, but if you need it for class then your exposed again.
Also at that age your not very careful yet, a MacBook Pro is a expensive and easily damaged machine.
Unless your made of money and so are others at your school, I would recommned a low profile, just does the job cheap Windows PC.
If it dies, gets lost, stolen or damaged because of your inexperince handling senstivie electronics then it's no big deal.
You can buy a Mac later on when your sure you have a need for it, currently there isn't much advantage of owning a Mac compared to a PC, they do just about the same things now, one just looks prettier than the other.
Since 95% of the world uses Windows PC's your going to have to install Windows on the Mac in order to keep your skills up there or be unemployed, so it's a extra headache and expense.
good luck

I have a macbook pro 13" early 2011 version and what to install windows 7 on it via bootcamp but not sure that whether to install x64 or x86 version? which one will work better

There is no need for anyone to use 32-bit version anymore.
Retail comes with both. Or you can save on just buying 64-bit System Builder disc.
Better support for today's hardware with larger video graphic memory and systems.
Better memory management.

Which one better to use - jsp:useBean or import statement

Hi,
I just want to know that which one is better to use jsp:useBean or import statement .
I can instantiate and call method of myclass -
1) by importing the class through import tag in jsp as <%@page import="myclass"%. or
2). by using <jsp:useBean tag....
i have these two option to do the same thing. i know that basically useBean is used to call setter and getter method of bean class and but it can be used to call a normal java file that have some logic .
so what should i used , which one is better and why?
useBean provides scope and object instance so no need to create object by new operator. and with import you have to create an instance .
but which tag should i use in my jsp?
i am confused???

ok, means i can use jsp:useBean tag for all my
classes that are not actually bean. so it will be
instantiated at run time and provide efficiency .No. Jsp:useBean is used for java bean components.
>
but when should i use import statement in my jsp and
it happen at translation time so will it create any
type of burden for my code if i import multiple
classes.For non-java beans, you need to import the classes, period.
It's not a burden, it's a necessity.
