Here Comes Automated Storage Tiering

At Storage Networking World, at least one new category in storage is coming to the forefront; Automated Storage Tiering. These are typically devices that can sit in front of your existing storage platform and allow some of it to leverage a high speed solid state front end without you manually having to move data to a Solid State Disk (SSD).

At Storage Networking World, at least one new category in storage is coming to the forefront; Automated Storage Tiering. These are typically devices that can sit in front of your existing storage platform and allow some of it to leverage a high speed solid state front end without you manually having to move data to a Solid State Disk (SSD).The companies in this space include Avere, Dataram, Gear6 and Storspeed. There are other forms of these products from Compellent and NetApp that either can do dynamic data placement or can provide a large SSD as a front end cache. These solutions however are limited to a single storage system and only work on the respective manufacturers products.

Integrating stand alone SSD or even SSD as a drive type in a storage system is achievable as we state in our recent article "Integrating SSD and Maintaining Disaster Recovery", but what if you don't have the time or what if your environment simply is too difficult to apply these procedures?

Automated Storage Tiering attempts to address the challenge of integration and provide increased optimization of tier 0 storage. After all if you are paying 15X the cost for your tier 0 storage, you don't want even 10% to be empty if you can avoid it.

The basic architecture behind automated tiering is to place the system inline between the storage and the servers. It then will act as a large, in some cases, giant, cache or I/O accelerator. Most of the systems today are DRAM based and then are adding flash SSD as a second tier. Typically the solutions will automatically cache reads and writes to the device. There are options for the storage manager to hard set or hard exclude certain data sets from the cache.

One of the differentiations between the automated tiering systems is going to be on protocol. Some will be block I/O focused and others network file system focused. The network file system storage devices may be able to provide greater analytics. There will also be debate around how the device is really used. Is the device a big cache that simply accelerates the current storage or is the device really a storage platform that leverages the legacy storage as the slowest tier in its available storage tiers?

Automated Storage Tiering is now a legitimate category. How we use this category to help IT to meet continuing storage I/O performance demands vs. some of the other options available to us is the next step.

The cybersecurity profession struggles to retain women (figures range from 10 to 20 percent). It's particularly worrisome for an industry with a rapidly growing number of vacant positions.

So why does the shortage of women continue to be worse in security than in other IT sectors? How can men in infosec be better allies for women; and how can women be better allies for one another? What is the industry doing to fix the problem -- what's working, and what isn't?

Is this really a problem at all? Are the low numbers simply an indication that women do not want to be in cybersecurity, and is it possible that more women will never want to be in cybersecurity? How many women would we need to see in the industry to declare success?

Join Dark Reading senior editor Sara Peters and guests Angela Knox of Cloudmark, Barrett Sellers of Arbor Networks, Regina Wallace-Jones of Facebook, Steve Christey Coley of MITRE, and Chris Roosenraad of M3AAWG on Wednesday, July 13 at 1 p.m. Eastern Time to discuss all this and more.
