CW ASEAN: June 2016

In this issue we look at a software-defined approach to storage management that combines storage, compute, networking and virtualization technologies. We find out how popular these hyper-converged and converged storage systems are among organizations in Southeast Asia and consider why organizations would move production systems to these. Also read whether Asian CIOs are ready for Docker and container technology. Containers are all the rage among developers. They are well suited to DevOps best practices due to their portability, fast deployment times and standard units of operations. We look at whether Asian CIOs are ready to use this open source technology to build, test and run applications in their organizations. Continue Reading

Guide to LUN configuration and virtualisation

LUN storage configuration has long been a cornerstone of storage management. The LUN – a chunk of storage created from RAID partitions on a SAN – presents a logical volume of capacity to an individual server. That’s still relevant today in the era of virtualisation. Many users retain physical servers that need a one-to-one connection between host and LUN. But, the role of the LUN is also changing with the rise of server and desktop virtualisation. It now forms a container for the logical objects used by VMware, Microsoft Hyper-V etc. In this guide you will find all you need to know about LUNs, LUN configuration and management, including their use in virtualised environments. Continue Reading

LTFS tape NAS: What it is and how to build it

In storage, cost is everything. So, imagine a storage medium with the frugal cost profile of tape and access times of NAS. Well, it already exists. Since 2010 the Linear Tape File System (LTFS) has allowed access to tapes as if they are spinning disk. Part of the LTO-5 tape format, LTFS partitions the tape, with one containing indexing information for all the data on the cartridge and the other contains the actual data. Marry this capability to a hardware NAS protocol front end with a disk cache and you have the potential for rapid access to massive amounts of data held on tape. Tiered storage is now mainstream. We have super-rapid flash for virtual machines and their data; Fibre Channel and 15k SAS for other fast access use cases. After that there is high-capacity SATA for bulk data, but here is where LTFS could start treading on the toes of disk vendors. That’s because, in some cases, where the use profile of data requires long retention and infrequent but relatively quick access, LTFS tape now rivals large capacity SATA as a nearline store. Maybe that’s why LTFS has failed to set the world on fire; there are just too many disk vendors who see it as a threat. Nevertheless, LTFS is worth looking at. And in this ComputerWeekly.com Guide you’ll find articles on why LTFS should be taken seriously and explanations of how tape NAS works and who sells products. Continue Reading
