Is Computer Data Storage Complex? It Depends

October 28, 2014 – 9:03 pm
Is Computer Data Storage Complex? It Depends I often get asked, or, told that computer data storage is complex with so many options to choose from, apples to oranges comparison among other things. On a recent trip to Europe while being interviewed by a Dutch journalist in Nijkerk Holland at a Brouwer Storage Consultancy event I was presenting at, the question came up again about storage complexity. Btw, you can read the article on data storage industry trends here (its in dutch). I hesitated and thought for a moment and responded that in some ways it's not as complex as some make it seem, although there is more to data storage than just cost per capacity. As I usually do when asked or told how complex data storage is my response is a mixed yes it (storage, data and information infrastructure) are complex, however lets put it in perspective which is ...

What does server storage I/O scaling mean to you?

October 28, 2014 – 7:59 pm
What does server storage I/O scaling mean to you? Scaling means different things to various people depending on the context or what it is referring to. For example, scaling can me having or doing more of something, or less as well as referring to how more, or less of something is implemented. Scaling occurs in a couple of different dimensions and ways: Application workload attributes - Performance, Availability, Capacity, Economics (PACE) Stability without compromise or increased complexity Dimension and direction - Scaling-up (vertical), scaling-out (horizontal), scaling-down Scaling PACE - Performance Availability Capacity Economics Often I hear people talk about scaling only in the context of space capacity. However there are aspects including performance, availability as well as scaling-up or scaling-out. Scaling from application workloads perspectives include four main group themes which are performance, availability, capacity and economics (as well as energy). Performance - Transactions, IOP's, bandwidth, response time, errors, quality of service Availability - Accessibility, durability, reliability, HA, BC, DR, ...

Lenovo ThinkServer TD340 StorageIO lab Review

October 28, 2014 – 2:07 pm
Lenovo ThinkServer TD340 Server and StorageIO lab Review Earlier this year I did a review of the Lenovo ThinkServer TS140 in the StorageIO Labs (see the review here), in fact I ended up buying a TS140 after the review, and a few months back picked up another one. This StorageIOlab review looks at the Lenovo ThinkServer TD340 Tower Server which besides having a larger model number than the TS140, it also has a lot more capabilities (server compute, memory, I/O slots and internal hot-swap storage bays. Pricing varies depending on specific configuration options, however at the time of this post Lenovo was advertising a starting price of $1,509 USD for a specific configuration here. You will need to select different options to decide your specific cost. The TD340 is one of the servers that Lenovo has had prior to its acquisition of IBM x86 server business that you can read about ...

VMware Cisco EMC VCE Zen and now server storage I/O convergence

October 22, 2014 – 2:58 pm
VMware Cisco EMC VCE Zen and now server storage I/O convergence In case you have not heard, the joint initiative (JV) founded in the fall of 2009 between Intel VMware Cisco and EMC called VCE had a change of ownership today. Well, kind of... Who is VCE and what's this Zen stuff? For those not familiar or who need a recap, VCE was created to create converged server, storage I/O networking hardware and software solutions combing technologies from its investors resulting in solutions called vBlocks. The major investors were Cisco who provides the converged servers and I/O networking along with associated management tools as well as EMC who provides the storage systems along with their associated management tools. Minority investors include VMware (who is majority owned by EMC) who provides the server virtualization aka software defined data center management tools and Intel whose's processor ...

Seagate has shipped over 10 Million storage HHDD’s, is that a lot?

September 21, 2014 – 11:33 pm
Seagate has shipped over 10 Million storage HHDD's, is that a lot? Recently Seagate made an announcement that they have shipped over 10 million Hybrid Hard Disk Drives (HHDD) also known as Solid State Hybrid Drives (SSHD) over that past few years. Disclosure Seagate has been a StorageIO client. I know where some of those desktop class HHDD's including Momentus XTs ended up as I bought some of the 500GB and 750GB models via Amazon and have them in various systems. Likewise I have installed in VMware servers the newer generation of enterprise class SSHD's which Seagate now refers to as Turbo models as companions to my older HHDD's What is a HHDD or SSHD? The HHDD's continue to evolve from initially accelerating reads to now being capable of speeding up write operations across different families (desktop/mobile, workstation and enterprise). What makes a HHDD or SSHD is that as their ...

CompTIA needs input for their Storage+ certification, can you help?

September 21, 2014 – 9:00 am
CompTIA needs input for their Storage+ certification, can you help? The CompTIA folks are looking for some comments and feedback from those who are involved with data storage in various ways as part of planning for their upcoming enhancements to the Storage+ certification testing. As a point of disclosure, I am member of the CompTIA Storage+ certification advisory committee (CAC), however I don’t get paid or receive any other type of renumeration for contributing my time to give them feedback and guidance other than a thank, Atta boy for giving back and playing it forward to help others in the IT community similar to what my predecessors did. I have been asked to pass this along to others (e.g. you or who ever forwards it on to you). Please take a few moments and feel free to share with others this link here to the survey for CompTIA ...

Despite being declared dead, Fibre Channel continues to evolve with FC-BB-6

August 24, 2014 – 9:12 am
Despite being declared dead, Fibre Channel continues to evolve with FC-BB-6 Like many technologies that have been around for more than a decade or two, they often get declared dead when something new appears and Fibre Channel (FC) for networking with your servers and storage falls into that category. It seems like just yesterday when iSCSI was appearing on the storage networking scene in the early 2000s that FC was declared dead yet it remains and continues to evolve including moving over Ethernet with FC over Ethernet (FCoE). Recently the Fibre Channel Industry Association (FCIA) made an announcement on the continued development and enhancements including FC-BB-6 that applies to both "classic" or "legacy" FC as well as the newer and emerging FCoE implementations. FCIA is not alone in the FCIA activity as they are as the name implies the industry consortium that works with the T11 standards folks. T11 is ...
