Flash Vendors Cut Pricing
By Deni Connor
InformationWeek
Sykera introduced the Skyhawk Series storage systems, which are made up of less-expensive multi-level cell (MLC) NAND flash. The Skyhawk appliances are available in a 1.75-inch-high (1U) form factor and contain 44 terabytes of flash. Before data is deduplicated, compressed, and stored on the Skyhawk arrays, the system prices out at $3 per gigabyte. When deduplicated and compressed data is stored on the Skyhawk arrays, the price decreases to $1 per gigabyte. The net capacity for deduplicated data is 100TB.
The Skyhawk Series storage systems are designed for big data, analytics, and server and desktop virtualization--environments that need high performance and low latency.
Skyera was founded by CEO Radoslav Danilak and Rod Mullendore, chief architect. Danilak previously founded Sandforce, which was acquired by LSI in 2011.

Working on changing and extending the write amplification--where memory needs to be erased before it can be rewritten and the rewriting shortens the life of the memory--of MLC flash was a challenge Skyera’s engineers undertook. They re-architected the entire stack including the flash and RAID controllers, storage blades, communication bus, and network interface to improve the life amplification of the flash. The resulting controller uses proprietary algorithms to tune the life of the flash and adjust its use as the flash ages.
The Skyera arrays also incorporate networking switching. The arrays are outfitted with 40 1GbE and three 10GbE ports.
Tegile Systems on Tuesday also rolled out two new flash arrays, the Zebi HA2400 and Zebi HA-2800. Each deduplicate, compress, RAID, and snapshot data. The HA2400 and 2800 use metadata accelerated storage system (MASS) technology to separate metadata from the primary data path, increasing IO performance as much as seven times. The new arrays sell at below $2 per gigabyte and use near-line SAS hard drives as well as solid state drives.
Tegile’s MASS architecture also now includes FlashVols to maximize performance. FlashVols are volumes pinned in solid state drives so the applications can run quickly without delays caused by caching algorithms or tiering.
The new arrays are available now. The HA2400 is $168,389. The HA2800 is $235,152.
Finally, SanDisk, which acquired FlashSoft earlier this year, released software for Windows and Linux servers that increases application performance and supports more virtual machines. The new software shows an increase of two to four times in application performance and supports two to three times the number of VMs. In addition, the software runs transparently within the hypervisor.
The FlashSoft software caches "hot" data on solid-state devices installed in the Windows or Linux server, thus reducing IO latency. It works with any Pie, SAS or SATA flash device from any vendor, both in storage area network and network attached storage configurations.
As much as 2TB of cache can deployed with the FlashSoft software. It costs $3,900 per server.

Informed CIO: VDI Snake Oil Check
You won't lose your shirt on a desktop virtualization initiative, but don't expect it to be simple to build or free of complications. This report examines the three biggest problems when developing a business case for VDI: storage costs, ongoing licensing, and the wisdom of prolonging the investment in PC infrastructure.
Fundamentals: Next-Generation VM Security
Server virtualization creates new security threats while turning the hypervisor into a network black hole, hiding traffic from traditional hardware defenses -- problems a new breed of virtualization-aware security software tackles head-on.
Delegation Delivers Virtualization Savings
IT can't-and shouldn't-maintain absolute control over highly virtualized infrastructures. Instituting a smart role-based control strategy to decentralize management can empower business units to prioritize their own data assets while freeing IT to focus on the next big project.
The Zen of Virtual Maintenance
Server virtualization has many advantages, but it can also lead to chaos. Many organizations have unused or test VMs running on production systems that consume memory, disk and power. This means critical resources may not be available in an emergency: say, when VMs on a failed machine try to move to another server. This can contribute to unplanned downtime and raise maintenance costs. Easy deployment also means business units may come knocking with more demands for applications and services. This report offers five steps to help IT get a handle on their virtual infrastructure.
Pervasive Virtualization: Time to Expand the Paradigm
Extending core virtualization concepts to storage, networking, I/O and application delivery is changing the face of the modern data center. In this Fundamentals report, we'll discuss all these areas in the context of four main precepts of virtualization.
Virtually Protected: Key Steps To Safeguarding Your VM Disk Files
We provide best practices for backing up VM disk files and building a resilient infrastructure that can tolerate hardware and software failures. After all, what's the point of constructing a virtualized infrastructure without a plan to keep systems up and running in case of a glitch--or outright disaster.
