Database performance on Solid state disks

Folks,
anyone has experience on running database on solid state disks ? what is the performance improvement ?

Dumb question-- is your database I/O bound? Or is it CPU bound? Or does it spend a lot of time reading data that has been cached in memory?
Many systems will bottleneck on things other than physically reading and writing data to disk, in which case improving disk performance won't help much. Some systems that are bottlenecked on disk performance will actually be slower on this sort of architecture because the faster physical reads swamp some other resource (i.e. the CPU) creating an even bigger bottleneck. Some systems that are bottlenecked on disk performance will be faster with faster disks. That's not something we can predict from a forum post.
As of yet, I haven't worked with a system that would derive sufficient benefit from solid state disks to justify their cost. I'm sure there are systems out there, though, that would.

My HP Pavilion Notebook can support a solid-state drive (SSD) (also known as a solid-state disk)

Hi,
Product Name dv6-6093ex
Product Number LM610EA
I don't know if my HP laptop can support a solid-state drive (SSD) (also known as a solid-state disk or not.

Thanks a lot,
I really checked out the prices of SSD at amazon.com
However, I found that the prices were relatively expensive.
120 GB
$88.49
250 GB
$132.00
500 GB
$231.99
1 TB
$439.95
Do you think it is worth purchasing SSD? Did you find any noticeable benefits since 439.95 dollars would let me purchase another laptop

X200s Replace Solid State Disk with 2,5 SATA Hard Drive

Hi, i want to replace my Solid State Disk with a regular hard drive. But I found out, that the Carrier in the HDD Bay for Solid State Disks doesn't have the form factor for a regular HD. My new Drive ist a Seagate Momentus 7200.4 500 GB 6,4 cm (2,5 Zoll) interne Festplatte HDD S-ATA 300 Mbit/s 7200rpm 1...
Any Suggestions where i can get a proper HD-carrier for the Bay?
Thanks in Advance,

Solid state disk

Hi All,
I recently have started using a solid-state drive (SSD) in my laptop, and it really flies (Intel X-25).
However, I am quite perturbed about the performance of Diadem 11.1 in loading files off this disk. Loading medium sized TDMS files (300 MB with 20 MB index files) seems to stall, ie the progress bar does not really move for long periods of time.
There is no problem with the disk, random reads and writes are exceptional on this SSD, and have not noticed this slowdown with any other applications. Any idea what is going on here?
Also, to muddy the situation, I am using this on Windows 7. Reading from a USB hard-drive seems to work as normal, so I figure its not the OS.
Any one else notice these kinds of problems?

Brad,
I tried using the load menu, it seems to make a bit of difference in that the loading progress bar goes a bit quicker, but it still seems to take its merry time, around 5 to 10 minutes. The hard drive light on my laptop does not even come on for tens of
seconds at a time when it is loading the original file, then there is a
burst of activity, then nothing again for like 30 seconds etc. Diadem CPU utilisation is very low during all this time and there is nothing else being done on the CPU.
The data is mostly DBLs, about 10 to 15 channels.
Slightly more weird, if I save the dataset once it has loaded (to compact the index file), then the subsequent loads are amazingly quick. I know you are probably thinking its just cached in memory (I have seen this before with a traditional hard disk), but the file loads in about 5 seconds from a cold-boot!
SSDs have very very good random read speeds, so even if the file was highly fragmented it should still be quite quick.
I have a pretty quick laptop (dual core mobile processer) with 4 GB of RAM. I have no problem loading four of these data sets into memory (reloading them after they have been saved), the load goes very quickly and when its done Diadem is happily using 2.5 GB of the RAM and there is no paging to the swap file.
I will never get permission to post the file unfortunately...
Any other ideas?
ps: you are right, 300 MB is more of a baby TDMS file... about 1 GB is medium sized ;-)

Anyone try a Solid-State Disk as PS Scratch Disk?

Has anyone tried using one of the new solid state drives such as the Intel X-18M as a Photoshop scratch disk? These have very low latency and ought to boost performance quite a lot. But I'd rather not spend the money without hearing if anyone's made the jump and likes the results.

I'm waiting for price to come down....the OCZ's are to avoided for now as they have issues with the sata controller bottlenecking the data causing stuttering/freezes.
But, this year should be good for SSD's as we are seeing 240mb/s and 200mb/s read/write speed drives starting to emerge....and the price is starting to fall......a bit...finally.
Best bet is to hold off until the SLC drives are affordable. MLC drives are OK, from what I can tell, but they will be slower.

Did you ever figure out the issue? I'm having a similar issue.

Solid state "disk" problem (additional to benchmark PPBM5 problem)

Just to give the discussion the right name from this point on. The benchmark PPBM5 test, as discussed in an earlier discussion, has led (thanks to Bill Gehrke) to the conclusion that the disk setup is very poor, and possibliy causes the problems in my system.
Asking the company who build the system they answerd that the OS and programma's are located a solid state (principally a faster system than a normal drive) C.
The projects run on two other disks D and E (1T), 7200 rpm and a third disk H (750G) 7200rpm.
The question is:
1.     Does PPRO and Audition accept the "solid state configuration? Can this maybe gives the problem of slow working drives
2.      If solid state is not accepted by Adobe, is is advisable to run the OS (Windows 7) on the solid state C and place all other programms on a seperate disk D?
3.       Or is it advisable to replace the (principally faster) solid state module for a fast normal drive 72000 rpm. with the OS and all the programms on it?

Texas RamSan Solid State Storage Appliance and Oracle VM 3.x

Has anyone had success with using a Texas Memory System RamSAN 810 (solid state appliance) and Fiber Channel controllers with Oracle VM 3.x
I believe any Fiber Channel device should work as shared storage, but looking for some extra confirmation that there were no issues before actually buying.
Thanks for any information.

886374 wrote:
In playing with OVM 3.0 so far, I see that local storage (as the accelerator cards would show up as) is not really appropriate for Production Systems. It appears I can create a Repository on these physical disks and then present them to the VM guest. Then add these cards as my Oracle ASM disks for my "fast" storage, and do the same with the FiberChannel storage for my "slower" disks. Because of the Local Storage used for part of the VM guest, we would not be able to Live Migrate or have High availability I believe. Is this correct? Correct.
If we have the two servers as mentioned above. Could I take the database VM down and move it to the other server (ie Cold Migration)? The local storage (ie the accelerator cards) could physically be moved from one physical host to the other, but I am not sure, since this is virtualized disk, if this would be allowed or how it could be recognized on the other Oracle VM Server. This might be a "dream", but might be something we would like to do if an emergency arose or if more maintenance needed to be done on Server 1. Any comments?You would have to shutdown the VM, migrate it to an unassigned folder, edit the VM, remove the local storage from Server 1, migrate to Server 2 and add the local storage from Server 2. Whether or not this means moving your hardware is up to you.
Does anyone have other solutions to run Solid State disks (approximately 2TB worth) and Oracle VM, running a single guest that runs the database? We have been unable to find iSCSI or FiberChannel enclosures that can handle solid state drives in the 1 to 2 TB range of capacity. So perhaps there are other enclosures out there that can act as Shared Storage that can operate with SSDs. Thank you for any comments and suggestions.I know the Sun storage appliances use hybrid storage, i.e. a mix of SSD/spinning disks, but I don't know the details. Our Exadata machines have 5TB of Flash storage per cell, so I know we have such options.

HT1661 Problems mounting Imac in target disk mode on retina laptop with a solid state drive as host

I'm trying to use an Imac in target disk mode to copy files from it to a new retina display laptop with a solid state drive, but the target drive will not mount even tho it does start in target disk mode. I have all the proper firewire connection. The Imac will not respond for more than a few minutes before crashing when started from its own system. I would like to salvage a few files from it before I perform a clean install of the system.
Anyone has any idea why it wont mount in Target mode onto the retina laptop? Help!
Thanks in advance. :-)

Mac OS X doesn't offer a "clean install" option.
I'm assuming your target Mac is running 10.6?
And you setup the target Mac without adding a Firewire cable until after the Firewire logo appears on the screen?

Lightroom and solid state hard disks

I'm looking to speed up Lightroom as much as possible within reason (version 3 on a Mac) and one possibility that occurred to me is to put Lightroom and it's catalog on a somewhat smaller 80-120 GB (and therefore less expensive) solid state hard disk. I'm wondering if Lightroom interacts with the system enough that I wouldn't gain much? I would think that I would get a pretty good speed bump...

Pete Marshall says:
SSD's are great for the OS and apps. They may not be so good for the catalog itself as write speeds are not good. If I was you I would get a small SSD to use as the boot drive and put the catalog and files on seprate fast traditional hard drives.
Write and read speed of currently available SSDs blow away hard disk drives in any configuration. Look here:
http://www.harddrivebenchmark.net/high_end_drives.html
SSDs are more expensive per GB than HDDs, but you don't need a large 1TB+ drive to increase system performance! I work with Intel who is one of the top SSD manufacturers and R&D companies. Intel is working with Micron on joint program to reduce cost of SSDs. Intel just announced their new SSD 510 series:
Intel SSD 510 Specification
SATA 6Gb/s Sustained Bandwidth Performance
(Iometer* Queue Depth 32)

Sequential Read: Up to 500 MB/s
Sequential Write: Up to 315 MB/s
— 120 GB:

I have no experience running LR on SSD, but putting your LR catalog, RAW cache, and preview files on an SSD should provide a real performance boost.

How do I copy my operating system to a solid state drive and make it the disk I boot from?

How do I copy my operating system to a solid state drive and make it the disc I boot from?

Where is your operating system now? Basically, you clone it from wherever it is now to the SSD:
Clone Lion/Mountain Lion using Restore Option of Disk Utility
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Select Disk Utility from the main menu then press the Continue button.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the SSD. Source means the drive now holding OS X.

What is largest solid state drive I can install in MacBook Pro 8,2? I want to perform a clean install of Mavricks and dump my old hard drive.

What is largest solid state drive I can install in MacBook Pro 8,2? I want to perform a clean install of Mavricks and dump my old hard drive.

If the bank account permits, I suggest getting a 1 TB SSD anyway. One cannot have too much storage.
Unless you are having issues with your current installation, a 'clean' install is not necessary. It would be more efficient to clone your current drive to the new SSD, test it, and then do the swap. The installation of Mavericks over Snow Leopard can be done either before or after the cloning process.
Ciao.
