Budget Conscious & Safe build out for 50 Users / 100TBOpen in a New Window

Currently I have three HP D2600 filled with 600GB SAS drives in raid 6 that is used for an imaging services bureau (18 million images / 18TB / accessed by 8 people).  I’m in the process of adding a fourth D2600 and 12 more 600GB SAS drives.

 

My primary capacity is a developer but I also handle all of the networking / infrastructure.  I’m hoping someone with more knowledge can help me with.

 

Question 1 - These D2600 are rated for up to daisy 4X 2600’s X 4 ext SAS on the P822 controller = 192 drives.  I’m getting nervous having 48 drives on one array.  

 

At what point do I hit “Too many drives” for a raid 6 (or RAID 60) array?  I have Array controller, 3 enclosures, 6 ext SAS connections as failure points.  Continuing to grow extends my points of failure - can someone help me gauge if these things were really intended to have 100+ drives on a single array?

 

Question 2 - Tentatively my next build out I need to support up to 100TB, 100 mil files & 50 employees .  The build out needs to start slow (immediate needs) & grow over time. I see three options (keeping things in the HP fold)

A - Keep adding to existing array with 600GB SAS 3.5 drives.

 

B - Use D2700 / 1.2GB 2.5 10K SCSI drives which will cut down on my enclosures / ext SAS connectors (less likely to fail?).

 

C - Get two MDS600 - two boxes to put everything in.  (Max 74TB high speed SAS w Raid 60).

 

But for whatever reason NONE of those options feel safe to me.  Maybe it’s because I don’t have experience running 100+ drives in a single array?  Or it’s actually a horrible idea?

 

Question 3 - Prior to an upgrade - the imaging department ran a Raid 6 Array using 25 7,200 RPM hard drives in an EMD Netstore (company no longer exists).  It supported up to 15 users doing imaging work.

 

Can I go back to 7,200 RPM HP Sata drives and support 50 people hitting the array?

P.S. Budget is important.

 

Configuring StorageWorks D2700Open in a New Window

Hi Everyone,

I purchased a used storage array to provide additional storage for an HP ProLiant DL980 equipped with a Smart Array P812 SAS controller.  The array is an HP StorageWorks D2700 configured with 12 3TB SAS hard drives.

The array starts up fine, green lights all around, no errors.

However, when I try to configure it using the ROM utility included with the P812 controller, it sees all 12 drives but says their capacity is "0.0GB SAS HDD" and won't configure the RAID array using any options I can find.  Meanwhile, the solid green lights on all the drives switch over to a blinking blue.

Can anyone give me some steps I can take to overcome this?  If the array is faulty, I can send it back for a refund but I need to determine that soon.

Extend Logical DriveOpen in a New Window

I used the HP Smart Storage Administrator to add my 3 new 8TB disks and extend the array. The logical drive shows that the space has been added, but in Disk Management the space is not allocated. When I go to extend the disk I get the messsage "The volume cannot be extended because the number of clusters will exceed the macimum number of clusters supported by the file system.". There for I have around 20TB of space that I cannot added to the Logical Drive.

 

<UPDATE>

So it appears it's a limitation to the cluster size. The current cluster size is set to 16K which will only allow 64TB partitions. I've allocated as much as I could to the existing partition, leaving about 1.4TB unallocated.

 

Enabling the Write Cache on existing production Storage Controller ?Open in a New Window

Hi People,

I've noticed that in my Storage Controller settings in the Smart Storage Admin, the Cache is not enabled ?

Controller Write Cache disabled ?Controller Write Cache disabled ?

If I just click on enabled is there any outage or data loss ?

The reason I enable it is because I need to improve the prformance of my RAID 5 LUNs.

Thanks in advance.

 

Bytes Per Physical Sector ?Open in a New Window

Missing Delete Logical Drive button ?Open in a New Window

People,

I'm trying to reconfigure the Strip Size / Full Stripe Size of an existing LUNs, but somehow I've found something that is confusing.

In some of the Logical Drive I mark with the red, when you click on those two logical drives in the screenshot below, the Delete Logical Drive is missing ?

Logical.JPG

But when you click on the Logical Drive 3 as shown above, the delete button is there.

Does this also means when I need to change the Strip Size / Full Stripe Size of Logical Drive 1, 2 and 3 I will need to delete all of them destroying all of the data ?

Any help would be greatly appreciated.

Thanks,

 

Migrate From RAID 6 ADG to RAID 5 without Data Lost on P420iOpen in a New Window

Hi,

 

Today I have a technician who add a new disk on a raid 5 and he migrate the RAID 5 to RAID 6 ADG.

He made a mistake because we need to ADD a disk to the existing RAID 5 to have more space available.

At this time the server is in production and I want to know if it is possible to migrate to RAID 5 wihout data lost.

The option is selectable in Smart Storage Administrator

Thank you for your ASAP response.

Kind regards

Vincent.

It now includes this line in the Smart Array P410i in Slot 0 (Embedded) section

Can anyone tell me what I should fo to stop this warning being triggered?

The hpacucli.exe report includes no other errors. All the logical drives have status "OK".

Smart Array P410 firmware update from 3.50 to 6.64?Open in a New Window

I have been investigating a performance problem on a Windows SBS 2011 virtual server hosted on a Microsoft Windows Hyper-V 2012 R2 server host. The virtual machine and virtual hard drive files are stored in a RAID5 array running on a Smart Array P410 controller.

To cut a long story short I used HPSSACLI to determine that one of the drives has a status of 'Predictive Failure' but also noticed that this controller is running firmware version 3.50. The latest is currently 6.64.

My question is: "Is it safe to upgrade the firmware directly from 3..50 to 6.64?

DC power supplies for a D2700?Open in a New Window

I can't find a reference to anything that says these exist.  I see that the D2700 takes a "common slot" PSU, and there's a DC chassis for a P2000 (to which the DC D2700 attaches), but there isn't a VDC power supply listed in the D2000 quickspecs (for either the D2600 or D2700), so i'm concerned that i'll blow something up if I try it.  Can anyone help steer me in the right direction? 

Basically what we have is 4 of these D2700s attached to a DL360pG8, and will soon moving everything to a DC power environment.  The current PSU in everything (G8 and D2700) is a 460W VAC PSU.  The smallest VDC version is 750W, and if that will work for both of these systems, that would be great. 

Thanks!
