Cloud Storage Effect on Storage Management: Reduced Complexity, Maximized Resources, Improved Efficiency

Monday, January 24th, 2011

 

IT administrators continue to face the age-old challenges of storage management complexity and cost while the burden of managing exponential data growth has businesses of all sizes considering the best ways to store, protect, and archive their files, Exchange, and SharePoint data. The need to maximize resources and infrastructure, optimize storage requirements, and improve efficiencies remain top drivers for most of these businesses today. 

With all of these factors to consider, one of the most difficult skill sets for IT to find and retain are expert level administrators for specific storage management disciplines including storage administrators.

When you deploy an Enterprise or Mid-Range storage array, you generally need a team of people who are specialized in configuring, provisioning, and managing those storage arrays (let alone the compliance, disaster recovery, and other more advanced storage specializations).  Decisions made daily include RAID configuration, performance tuning, device management, storage pool provisioning, management of remote replication, management of consistency groups, and management of capacity and storage tiering. These are highly specialized and vendor specific skills. They will extend out to your application servers with CLI and API command sets which must be used to perform even simple client side tasks.

Most, if not all of these technology skill demands will disappear once you deploy Cloud Storage. Of course, if you deploy a Private Cloud, you will merely be moving the skill pools to a different area, but they will still largely vanish from your day-to-day data center operations.  With Public Clouds, they will go away almost immediately and entirely.

As Cloud Storage gets provisioned through CloudArray, your administrators will largely be working at the level of an average system administrator skill set when it comes to provisioning and managing storage.  Configuration requirements will be reduced to basic volume count, volume size, encryption requirements, and page size requirements.  None of this requires advanced degrees, decades of storage management experience, or high level vendor certifications.

By deploying a Cloud Storage model – especially for routine use cases such as online backup, archive, and disaster recovery operations – you can begin to free up highly skilled administrators and other IT specialists to redeploy and focus on other critical areas of your IT operations. Cloud Storage doesn’t necessarily mean direct reductions in headcount. Efficiency is in part about resource re-deployment without having to incur additional costs for people or infrastructure. Conversely, Cloud Storage might even allow growth in areas you otherwise couldn’t hire into before.

Essentially, as more leading-edge technologies begin to creep into IT shops and data centers, Cloud Storage is a direct and immediate way to reduce management complexity and costs affording IT the chance to spend more time on business applications, business continuity, and strategic IT planning and projects.

Cloud Storage Performance: I/O Does Matter

Tuesday, January 11th, 2011

 

One of the first decisions you will need to make when tuning your environment for Cloud Storage I/O is what page size you will use to perform writes to your Cloud Storage Provider (CSP).  This is one of the configuration parameters you will enter when configuring a new volume in CloudArray. 

Page sizing is an important consideration, and represents the smallest unit of data that will be sent to your CSP from your CloudArray appliance, or read back when needed. Choose a size that is too small and you may have to do a lot more I/Os if you need to move a lot of data in bulk.  Choose a size that’s too big and you will move more data than you need to.

For example, if your application needs to read a lot of small chunks of data that don’t already reside in your CloudArray cache, then CloudArray will have to issue read requests to the CSP for each of those chunks.  If each chunk was 64K in length, and they weren’t contiguous, then CloudArray might have to issue 4 separate read requests for that data.  If the data were contiguous, then only 1 read request would need to be made.

Larger Page Sizes will result in more data being read than is needed for the current operation, but it may help performance if that data is needed at any point while it is still in cache. In CloudArray, you can choose variable page sizes from 128 KB (default) all the way to 2 MB.  512 KB is the recommended value for backups and in cases where there is a lot of sequential I/O. 

If you do a lot of random small block I/O, you should choose the smaller default page size.  This will prevent having to move a lot of empty data between your CSP and the CloudArray appliance.  A large page size here will cause slower overall performance since a lot more pages will have to be written to accommodate the data requirements. Likewise, if you are doing backups, you will want the 512 KB (or larger) page size.  This will result in fewer overall writes compared to a smaller block size and performance will increase.

This can have an impact in your cost model as well, but nowhere nearly as much as some vendors selling file system-based appliances would have you believe.  Some CSP’s will charge a small per transaction fee for each read or write request you make.   For Amazon S3 for example, the charge is $0.00001 per write transaction.  And so for a 1TB backup, that amounts to 8,388,608 x 128KB transactions, or $83.  If you used a 512KB page size, that would amount to 2,097,152 write transactions, or $20 for the write transaction costs.  Reads are cheaper by an order of ten.  That’s a far cry from the $1K+ figure for a 100GB write that another vendor would cost you.

BNMC Relies on TwinStrata CloudArray and Best Practices to Avoid Disastrous Data Loss

Thursday, December 23rd, 2010

 

Customer Success: Critical Business Data Saved

BNMC; a Mass. based strategic information technology (IT) network services company, selected TwinStrata CloudArray® to provide backup services for their clients. A virtual appliance that runs on VMware, CloudArray can be deployed for backup, archive, or disaster recovery/business continuity requirements. Key to effective and rapid data recovery in the event of a site disaster is CloudArray‟s metadata so protecting this critical information is top of mind for system administrators. Eryck Bredy, BNMC President & CTO, has always been an advocate of following best practices and one day, he averted a disaster as a result. You see, Eryck accidentally deleted the CloudArray VM he was working on, rendering it terminal. This VM had 1TB of customer data on it. But Eryck wasn‟t worried. He knew that he could easily recover the data with CloudArray since he did, in fact, follow best practices, and had backed up the CloudArray configuration data. And because there was a full copy of the data in the cloud, he knew CloudArray was imminently recoverable in and of itself. After accidentally deleting the CloudArray VM (CAVM1), Eryck simply imported a new CloudArray VM (CAVM2), reset t he cache, and restored the backup of CAVM1 to CAVM2. That was it. When CAVM2 was powered on, it replayed the metadata and back-filled its cache with the data from the cloud on an as needed basis. Because of the rapid and seamless recovery capabilities of CloudArray, BNMC business interruption was avoided. And since all user data was in the cloud, CAVM2 simply re-enabled access to it without incident.

“Bottom line – unfortunate incidents are going to happen. The important thing is to be ready when they do. Using TwinStrata CloudArray helped us mitigate the effects of losing critical data and enabled us to protect the trust our customers have in BNMC.” – Eryck Bredy, BNMC President & CTO

As widespread adoption of cloud services increases, it‟s comforting to BNMC to know that solutions like CloudArray are in place to help. For Eryck, the combination of CloudArray and BNMC best practices helped avoid a potentially disastrous situation for their clients, the loss of their critical business data.

I Have NOT Lost My Mind — I Have It Backed Up On Tape Somewhere

Monday, December 6th, 2010

 

The question is: If you can eliminate tape, then can you even eliminate backup? In a recent article, George Crump (http://www.networkcomputing.com/deduplication/you-can-eliminate-backups.php) discussed the implications of eliminating backup altogether.  His argument is that with the capabilities of modern storage systems – snapshots, deduplication, compression and replication– you can preserve multiple restore points without the need for a separate backup operation. 

He specifically argues: “Using a combination of snapshots, deduplication, compression and replication is a cost-effective way of storing redundant copies. Many primary storage systems support a high number of snapshots and/or unlimited copies of data by leveraging deduplication. Most can then have that data replicated to a remote site so you are covered for a single site disaster. With these features deployed, we now have point-in-time local recovery and total system recovery in case of a disaster covered, but there are some potential drawbacks.”

Using Cloud Storage as the remote replication target in this case will work very well, and will be more cost effective than using your expensive primary storage devices for backup.  

With CloudArray, you can create instantaneous snapshots of your data, allowing you to establish multiple remote restore points from a single copy of your data.   This doesn’t have to be your primary data store. Cloud Storage can actually become an economical cog in your tiered storage strategy.

But getting back to George’s article, he discusses several drawbacks with using primary storage as your source for your restore points.  Basically, they come down to the risk, however small, of not having a separate copy of your data (both physically and logically).  Even in cases where you are replicating your data to a remote facility, a logical corruption fault could affect both sites, especially if the fault were with the logic of the de-duplication engine itself.

Some companies have eliminated separate backups very successfully, but it takes a great deal of planning in order to make sure that the restore points will be consistent across applications and data stores. It wouldn’t help you to have your accounts payable tables backed up at one point in time and your inventory shipments at a different point. 

But is it right for you? 

Maybe, but a safer approach is to still use backup software and write your backup to a physically separate data store than your primary storage.  CloudArray can do this for you as well.  If you use a backup product that can write to disk (D2D), then you can write to CloudArray and a copy of the backup images will be kept locally as well as in the Cloud.  Restores will always come from the local CloudArray disk cache if you size it properly, and in the event of a total site disruption, a copy of your data will still be housed safely offsite and can be recovered from any site you choose.

Eliminating tape is a good first step. Eliminating backup entirely might be an option for you down the road (or not). Remember the cardinal rule: “To go forward, you must backup.” So you probably shouldn’t be in a rush to eliminate it. But if you have lost your mind because you’ve backed it up on tape somewhere, then without CloudArray, you may never get it back!
