Part II: How many IOPS can a HDD, HHDD or SSD do with VMware?

May 19, 2013 – 10:12 pm
How many IOPS can a HDD, HHDD or SSD do? This is the second post of a two-part series looking at storage performance, specifically in the context of drive or device (e.g. mediums) characteristics across HDD, HHDD and SSD. In the first post the focus was around putting some context around drive or device performance with the second part looking at some workload characteristics (e.g. benchmarks). A common question is how many IOPS (IO Operations Per Second) can a storage device or system do? The answer is or should be it depends. Here are some examples to give you some more insight. For example, the following shows how IOPS vary by changing the percent of reads, writes, random and sequential for a 4K (4,096 bytes or 4 KBytes) IO size with each test step (4 minutes each). ...

How many IOPS can a HDD, HHDD or SSD do?

May 19, 2013 – 10:12 pm
How many IOPS can a HDD, HHDD or SSD do? A common question I run across is how many IOPS (IO Operations Per Second) can a storage device or system do or give. The answer is or should be it depends. This is the first of a two-part series looking at storage performance, and in context specifically around drive or device (e.g. mediums) characteristics across HDD, HHDD and SSD that can be found in cloud, virtual, and legacy environments. In this first part the focus is around putting some context around drive or device performance with the second part looking at some workload characteristics (e.g. benchmarks). What about cloud, tape, storage systems or appliance? Lets leave those for a different discussion at another time. Getting started Part of my interest in tools, metrics that matter, measurements, analyst, forecasting ties back to having been a server, storage and IO performance and capacity planning analyst when ...

FusionIO (FIO) SSD vendor CEO out in a flash, whats up with that?

May 8, 2013 – 12:38 pm
FusionIO (FIO) who recently bought Nexgen to expand their reach from just a server centric to a more broad flash focus has seen their CEO and founder David Flynn race out the door. Not surprisingly, wall street who does not like to be surprised were surprised just a week or two after the most recent earning announcements reacted with a sell off of the FIO stock. Here is the conundrum, those who were or are fans of Flynn, FIO and their approach along with server centric in your face approach may not be happy with this move. On the other hand, those were not fans of Flynn, FIO and their approach of getting in your face of having others do so if you did not fall into their ranks may be happy with this move. One question is was Flynn shown the ...

EMC ViPR software defined object storage part III

May 7, 2013 – 11:28 am
This is part III in a series of posts pertaining to EMC ViPR software defined storage and object storage. You can read part I here and part II here. More on the object opportunity Other object access includes OpenStack storage part Swift, AWS S3 HTTP and REST API access. This also includes ViPR supporting EMC Atmos, VNX and Isilon arrays as southbound persistent storage in addition. Object (and cloud) storage access example EMC is claiming that over 250 VNX systems can be abstracted to support scaling with stability (performance, availability, capacity, economics) using ViPR. Third party storage will be supported along with software such as OpenStack Swift, Ceph and others running on commodity hardware. Note that EMC has some history with object storage and access including Centera and Atmos. Visit the micro site I have setup called www.objectstoragecenter.com and watch for more content ...

EMC ViPR software defined object storage part II

May 7, 2013 – 11:27 am
This is part II in a series of posts pertaining to EMC ViPR software defined storage and object storage. You can read part I here and part III here. Some questions and discussion topics pertaining to ViPR: Whom is ViPR for? Organizations that need to scale with stability across EMC, third-party or open storage software stacks and commodity hardware. This applies to large and small enterprise, cloud service providers, managed service providers, virtual and cloud environments/ What this means for EMC hardware/platform/systems? They can continue to be used as is, or work with ViPR or other deployment modes. Does this mean EMC storage systems are nearing their end of life? IMHO for the most part not yet, granted there will be some scenarios where new products will be used vs. others, or existing ones used in new ways for different things. As has been the case for years if not ...

EMC ViPR virtual physical object and software defined storage (SDS)

May 6, 2013 – 1:06 pm
Introducing EMC ViPR This is the first in a three part series, read part II here, and part III here. During the recent EMCworld event in Las Vegas among other things, EMC announced ViPR (read announcement here) . Note that this ViPR is not the same EMC Viper project from a few years ago that was focused on data footprint reduction (DFR) including dedupe. ViPR has been in the works for a couple of years taking a step back rethinking how storage is can be used going forward. ViPR is not a technology creation developed in a vacuum instead includes customer feedback, wants and needs. Its core themes are extensible, open and scalable. On the other hand, ViPR addresses plenty of buzzword bingo themes including: Agility, flexibility, multi-tenancy, orchestration Virtual appliance and control plane Data services and storage management ...

Spring SNW 2013, Storage Networking World Recap

April 23, 2013 – 3:52 pm
A couple of weeks ago I attended the spring 2013 Storage Networking World (SNW) in Orlando Florida. Talking with SNIA Chairman Wayne Adams and SNIA Director Leo Legar this was the 28th edition of the US SNW (two shows a year), plus the international ones. While I have not been to all 28 of the US SNWs, I have been to a couple of dozen SNWs in the US, Europe and Brazil going back to around 2001 as an attendee, main stage as well as breakout, and tutorial presenter (see here and here). For the spring 2013 SNW I was there for a mix of meetings, analyst briefings, attending the expo, doing some podcasts (see below), meeting with IT professionals (e.g. customers), VARs, vendors along with presenting three sessions (you can download them and others here). Some of the buzz ...

How a pressure cooker should be used for good things

April 21, 2013 – 10:01 pm
How a pressure cooker should be used for good things First, let me say condolences to those and their families that were killed and/or injured in the tragic terrorist act at the Boston marathon bombings this past week. Second, let me say thank you and congratulations to all of those involved in capturing one of the suspects and terminating another. This also goes to all of those who helped with tips and sending in large amounts of photos, video and other big data that was and is being used by investigators. Also best wishes to the prosecutors and their forensic investigators to tie the pieces together bringing the captured suspect to justice including determining a motive. Of course, also speedy recovery to those maimed or injured by the pressure cooker bombs. Let us talk about pressure cookers, and not in how they were used in ...

HP Moonshot 1500 software defined capable compute servers

April 8, 2013 – 12:38 pm
Riding the current software defined data center (SDC) wave being led by the likes of VMware and software defined networking (SDN) also championed by VMware via their acquisition of Nicira last year, Software Defined Marketing (SDM) is in full force. HP being a player in providing the core building blocks for traditional little data and big data, along with physical, virtual, converged, cloud and software defined has announced a new compute, processor or server platform called the Moonshot 1500. Software defined marketing aside, there are some real and interesting things from a technology standpoint that HP is doing with the Moonshot 1500 along with other vendors who are offering micro server based solutions. First, for those who see server (processor and compute) improvements as being more and faster cores (and threads) per socket, along with extra memory, not to mention 10GbE or 40GbE networking and PCIe expansion or IO connectivity, ...
