Mix luns from 300 and 146gb drives when provisioning storage capacity

Ldavis100 — Mon, 16 May 2011 13:15:49 +0000

We need to add capacity to our EMC DMX4 which currently has 146 and 300gb 15k drives. The 146gb drives may be difficult to get so my questions is given todays technology with drive IOPS, should it be a concern if I need to expand the amount of disk to an existing host that currently has 146gb drives with luns from some 300gb drives? Should mixing luns assigned to a host from diffenernt drive geometries be a problem for relatively high IO applications of mixed random reads and writes?

Software to ensure users store files in a central location only

TeachMeIT — Tue, 01 Mar 2011 18:00:54 +0000

Is there an application that limits where users can store files? I’d like to ensure that users save only to our shared cloud storage rather than to the local drive or My Documents. Is there anything like this?

What’s the right backup tape for 15 terabyte backup?

ITKE — Wed, 21 Jul 2010 14:05:42 +0000

What is the right backup tape for me if I am trying to get 15 terabytes backed up? We currently have a LTO3 library but I would love to replace it with higher capacity tapes. Are there any that are reliable? What application should I be using for backups this huge?

What is the best solution (DVR, NVR or SAN) for video storage with 300 terabyte per day for 90 days storage?

ITKE — Mon, 07 Jun 2010 16:32:16 +0000

I am asking about a video surveillance storage solution as we have to store 100 terabytes/day of live video stream that is coming from 900 PTZ cameras. We also have to keep the recordings in storage for 90 days before archiving.

Suggestions for home storage solution

ITKE — Thu, 03 Jun 2010 13:22:21 +0000

I work at home, and I often have files upwards of 4GB. Would a normal NAS FAT32 be adequate or do I need a NTFS because of file size? How is data recovery with NTFS if something happens to the NAS? Would I need to buy a GLAN? Any advice, including brands, is welcome.

Digital photo and video archiving software

ITKE — Thu, 27 May 2010 17:50:39 +0000

We are looking into a way to store, tag, and preserve our photos digitally.

There are a number of people who must access these photos and need the capability to get both low-res (for most purposes) and high res photos. We also need a way to easily go through the pictures and find specific photos based on a number of criteria.

We also want our teachers (this is a K-12 school) to be able to store pictures and tag/identify events and people in the pictures.

Two different methods that we are looking into are purchasing a network drive and then software to deal with the archiving and categorizing of the pictures.

The issues we see is that we still have to maintain a backup.

No way to ensure the photos survive in the event of someone stealing the hardware or a fire.
Difficult to access photos off campus.
Software needs to work for both Mac & PC Users and be adaptable to the future requirements of photos.

A second option we are looking into is a cloud computing option such as Flickr’s pro-account.

We still have to think about how to back up the information, since most of them don’t seem to insure backup.

Security is also more of a concern. We wouldn’t want just anyone to be able to access these pictures.

Our Art Department also wants to create an archive of student art work.

My question is about whether anyone has found a successful way to digitally archiving and categorizing pictures.

Criteria to test performance of synchronous replication

Ashmi — Fri, 16 Oct 2009 10:01:04 +0000

Hi,
I am working on synchronous replication implementation.
Can anybody tell what are the parameters or criterias on which our synchronous replication implementation may be compared with other sync replication implementations?
Also, can anybody provide us with any testbed report link?
