Server storage I/O Intel NUC nick knack notes – First impressions

January 6, 2015 – 5:35 pm
Server storage I/O Intel NUC nick knack notes - First impressions This is the first of a two-part (part II here) series of my experiences (and impressions) using an Intel NUC ( a 4th generation model) for various things about cloud, virtual, physical and software defined server storage I/O networking. The NUC has been around new for a few years and continues to evolve and recently I bought my first one (e.g. a 4th generation model) to join some other servers that I have. My reason for getting a NUC is to use it as a simple low-power platform to run different software on including bare-metal OS, hypervisors, cloud, virtual and software defined server storage and networking applications on that might otherwise be on an old laptop or mini-tower.

Intel® NUC with Intel® Core™ i5 Processor and 2.5-Inch Drive Support (NUC5i5RYH) via Intel.com What you will want to add to a NUC Since the NUC is a basic brick with a processor mounted on its mother board, you will need to add memory, some type of persistent storage device (mSATA, SATA or USB based) and optionally a WiFi card. One of the nice things about the NUC is that in many ways it is the equivalent functionality of a laptop or mini-tower ...

Revisiting RAID storage remains relevant and resources

December 23, 2014 – 12:36 am
Revisiting RAID storage remains relevant and resources If RAID were really not relevant anymore (e.g. actually dead), why do some people spend so much time trying to convince others that it is dead or to use a different RAID level or enhanced RAID or beyond raid with related advanced approaches? When you hear RAID, what comes to mind? A legacy monolithic storage system that supports narrow 4, 5 or 6 drive wide stripe sets or a modern system support dozens of drives in a RAID group with different options? RAID means many things, likewise there are different implementations (hardware, software, systems, adapters, operating systems) with various functionality, some better than others. For example, which of the items in the following figure come to mind, or perhaps are new to your RAID vocabulary? There are Many Variations of RAID Storage some for the enterprise, some for SMB, SOHO or consumer. Some have better performance than ...

DIY converged server software defined storage on a budget using Lenovo TS140

December 17, 2014 – 4:43 pm
Attention DIY Converged Server Storage Bargain Shoppers Software defined storage on a budget with Lenovo TS140 Recently I put together a two-part series of some server storage I/O items to get a geek for a gift (read part I here and part II here) that also contain items that can be used for accessorizing servers such as the Lenovo ThinkServer TS140. Image via Lenovo.com Likewise I have done reviews of the Lenovo ThinkServer TS140 in the past which included me liking them and buying some (read the reviews here and here), along with a review of the larger TD340 here. Why is this of interest Do you need or want to do a Do It Yourself (DIY) build of a small server compute cluster, or a software defined storage cluster (e.g. scale-out), or perhaps a converged storage for VMware VSAN, Microsoft SOFS or something else? Do you need a new server, second or third ...

Part II 2014 Server Storage I/O Geek Gift ideas

December 14, 2014 – 8:58 pm
Part II 2014 Server Storage I/O Geek Gift ideas This is part two of a two part series for what to get a geek for a gift, read part one here. KVM switch Not to be confused with a software defined network (SDN) switch for the KVM virtualization hypervisor, how about the other KVM switch? My KVM switch in use, looks like five servers are powered on. If you have several servers or devices that need a Keyboard Video Mouse connection, or are using A/B box or other devices, why not combine using a KVM switch. I bought the Startech shown above from Amazon which works out to be under $40 a port (connection) meaning I do not have to have Keyboards, Video monitors or Mouse for each of those systems. With my KVM shown above, I have used the easy setup to name each of the ports via the management software so that when ...

Data Storage Tape Update V2014, Its Still Alive

December 10, 2014 – 10:54 pm
Data Storage Tape Update V2014, It's Still Alive A year or so ago I did a piece tape is still alive, or at least in conversations and discussions. Despite being declared dead for decades, and will probably stay being declared dead for years to come, magnetic tape is in fact still alive being used by some organizations, granted its role is changing while the technology still evolves. Here is the memo I received today from the PR folks of the Tape Storage Council (e.g. tape vendors marketing consortium) and for simplicity (mine), I'm posting it here for you to read in its entirety vs. possibly in pieces elsewhere. Note that this is basically a tape status and collection of marketing and press release talking points, however you can get an idea of the current messaging, who is using tape and technology updates. Tape Data Storage in 2014 and looking towards 2015 True to ...

Cloud Conversations: Revisiting re:Invent 2014 and other AWS updates

November 30, 2014 – 11:38 am
This is part one of a two-part series about Amazon Web Services (AWS) re:Invent 2014 and other recent cloud updates, read part two here. Revisiting re:Invent 2014 and other AWS updates A few weeks ago I attended Amazon Web Service (AWS) re:Invent 2014 in Las Vegas for a few days. For those of you who have not yet attended this event, I recommend adding it to your agenda. If you have interest in compute servers, networking, storage, development tools or management of cloud (public, private, hybrid), virtualization and related topic themes, you should check out AWS re:invent. AWS made several announcements at re:invent including many around development tools, compute and data storage services. One of those to keep an eye on is cloud based Aurora relational database service that complement existing RDS tools. Aurora is positioned as an alternative to traditional SQL based transactional databases commonly found in enterprise environments (e.g. ...

Seagate 1200 12Gbs Enterprise SAS SSD StorgeIO lab review

November 4, 2014 – 5:59 pm
Seagate 1200 12Gbs Enterprise SAS SSD StorgeIO lab review This is the first post of a two part series, read the second post here. Earlier this year I had the opportunity to test drive some Seagate 1200 12Gbs Enterprise SAS SSD's as a follow-up to some earlier activity trying their Enterprise TurboBoost Drives. Disclosure: Seagate has been a StorageIO client and was also the sponsor of this white paper and associated proof-points mentioned in this post. The question to ask yourself is not if flash Solid State Device (SSD) technologies are in your future, Instead the questions are when, where, using what, how to configure and related themes. SSD including traditional DRAM and NAND flash-based technologies are like real estate where location matters; however, there are different types of properties to meet various needs. This means leveraging different types of NAND flash SSD technologies in different locations in a complementary and cooperative aka ...

Earlier this year I had the opportunity to test drive some Seagate 1200 12Gbs Enterprise SAS SSD's as a follow-up to some earlier activity trying their Enterprise TurboBoost Drives. Disclosure: Seagate has been a StorageIO client and was also the sponsor of this white paper and associated proof-points mentioned in this post. The Server Storage I/O Blender Effect Bottleneck The earlier proof-points focused on SSD as a target or storage device. In the following proof-points, the Seagate Enterprise 1200 SSD is used as a shared read cache (write-through). Using a write-through cache enables a given amount of SSD to give a performance benefit to other local and networked storage devices. Non-virtualized servers with dedicated storage and I/O paths. Aggregation causes aggravation with I/O bottlenecks because of consolidation using server ...
