Needed: Easy to Use Storage Encryption

c10d7-digitalprivacyinstory

Post by Henry Newman (thank you)

All enterprise disk drives today support some type of encryption at the drive level, at least those from the big 3 vendors. But I’m not sure about some of the enterprise SSD vendors, though that’s not the point.  I know of very few people using the full disk encryption for enterprise disk and SSD drives.  So I asked myself the question why not?

SAS vs. SATA

Post by Jeffrey Layton (thank you)

There has been a perennial argument of SAS versus SATA for enterprise storage. Some people say it’s OK to use SATA for enterprise storage and some say that you need to use SAS. In this article I’m going to address two aspects of the SAS vs. SATA argument. The first is about the drives themselves, SATA drives and SAS drives. The second is about data integrity in regard to SATA channels and SAS channels (channels are the connections from the drives to the Host Bus Adapter – HBA).

The Bleak Future of NAND Flash Memory

Good Paper by Laura M. Grupp, John D. Davis and Steven Swanson (thank you)

In recent years, flash-based SSDs have grown enor- mously both in capacity and popularity. In high- performance enterprise storage applications, accelerating adoption of SSDs is predicated on the ability of manufacturers to deliver performance that far exceeds disks while closing the gap in cost per gigabyte. However, while flash density continues to improve, other metrics such as a reliability, endurance, and performance are all declining. As a result, building larger-capacity flash- based SSDs that are reliable enough to be useful in enterprise settings and high-performance enough to justify their cost will become challenging.

Cloud-scale Object Storage – where do you store the cloud itself?

Post by Eric Slack (thank you)

“The Cloud”, a ubiquitous term for near limitless storage and compute capacity, may seem like a fantasy to users but the infrastructure challenges it brings are very real indeed. Just ask the ‘hyper-scale’ companies that have developed their own systems to support this explosion of data stoked by internet and the Internet of Things. Scale-out, object-based storage architectures are ideal for these unstructured data sets but the commercially available solutions cloud providers and enterprise companies must use have limits. Now “Himalaya”, the latest storage architecture from Amplidata, promises to keep the object storage cloud ahead of the data growth curve.

Software Defined Storage, which phase are you in?!

Post by Duncan Epping (thank you)

Working within R&D at VMware means you typically work with technology which is 1 – 2 years out, and discuss futures of products which are 2-3 years. Especially in the storage  space a lot has changed.

Why backup is failing and how to save it

Post by Eric Slack (thank you)

The traditional backup process doesn’t work well any more. It’s being overwhelmed by a new kind of file-based data that’s created, seldom modified, and saved – sometimes forever. Driven by industry trends such as big data analytics, image-based digital content and a “save everything” mindset, companies are finding they need something different to store and protect data.

Traditional backup was designed to provide protection for files and database applications that changed on a regular basis over a period of days or weeks.

Western Digital Gets NAS-ty with New Red Pro HDDs

Post by Pedro Hernandez (thank you)

Solid-state drives (SSDs) may be monopolizing the spotlight, but Western Digital continues to make the case for traditional hard disk drives (HDDs) in today’s storage infrastructures.

The Irvine, Calif.-based hard drive manufacturer has launched a new line of 3.5-inch SATA HDDs for network-attached storage (NAS) systems called Red Pro. The drives, which spin at 7,200 RPM, are best suited for 8 to 16 bay NAS systems, according to the company. Red Pro drives ship in capacities of 2 TB, 3 TB and 4 TB and feature 64 MB of built-in cache.

Quantum polishes its DXi range

Post by Chris Mellor (thank you) over at El Reg

Quantum has refreshed its dedupe box operating system and run up a fresh and faster hardware box. The DXi range before this announcement consisted of the V-Series software-only product and four hardware and software products:

  • V-Series: 1 – 24TB of usable capacity and up to 4.9TB/hour
  • 4700: 5 – 135TB and up to 5.9TB/hour
  • 6700: 8 – 80TB and up to 9.1TB/hour
  • 6800: 13 – 156TB and up to 16.3TB/hour
  • 8500: 45 – 330TB and up to 11.1TB/hour

Have we hit a flash point with flash?

Good Post by Calvin Zito (thank you)

I took a long vacation – 4 weeks, flying off to Europe the day after HP Discover ended. Now that I’m back, I thought I would take a couple of hot topics and break them down over my next couple of posts.

One of the hot topics is flash. Yeah, sure – industry pundits have been proclaiming that “this is the year” of flash for several years. I remember one storage vendor in 2009 saying that within 3 years, SSD would out-sell spinning disks. We aren’t there yet but I think the time is near and here’s why.

ChalkTalk Video – The Veeam Backup Challenge

Post by Charlie Hodges (thank you)

Veeam and other virtualization specific backup products have solved many of the data protection problems that slowed down initial server virtualization deployments. These solutions, and now even some traditional enterprise backup applications, offer the ability to cut the amount of data being backed up and reduce the amount of time it takes to recover a failed virtual machine (VM). The problem is that applications like Veeam demand more from the disk backup system and traditional solutions may fall short.
