Today I did a thing, that I postponed many days. I’ve finally moved Pytrend environment to Linux.

Pytrend. Quick demo of HPE 3PAR stats processing, time cuts and latency as a function of IOPS
In this short demo I am showing you that Pytrend now can process HPE 3PAR stats dumps and build various system level graphs, such as:
- IOPS over time (read/write/total)
- MB/sec over time (read/write/total)
- Latency over time (read/write/average)
- IO Size over time (read/write/average)
- CPU Utilization over time (system/user)
All above stats are directly parsed from dump into the graphs.
Though, there is another one, which I’ve added myself, because it is very useful to see how latency depends on IOPS, to see whether system resources (disks or controllers)are close to saturation.
Pytrend Enhancement. Quick demo for IBM DS3000 and DS5000 series
In this little demo I show you two improvements for storage stats processing.
One of them is small enhancement of IBM DS3000/DS5000 series statistics. Originally, DS-series do not provide average IO Size in their service dump, so I have taught Pytrend to recognize bandwidth (KB/sec or MB/sec) and IOPS data to correctly calculate average IO size.
Another small enhancement for graphs now shows Average and 95-percentile for each plotted value. It is required in most situation for determining correct workload profile. This feature is available for all storage types.
Pytrend — quick 3rd party storage array workload analysis. IBM DS5300 demo.
This is aimed at partners and Dell people…..
I’m often asked to analyse the performance of 3rd party arrays before I build a solution. We have many tools to analyse behavior, but sometimes you have to analyse the raw data from the 3rd party array, rather than use host-based tools, especially if there are hundreds of servers connected to the same array.
Unity: coming inline dedupe is not a secret anymore
Later this year we’ll unveil our data deduplication capabilities in Dell EMC Unity. We wanted to give an early glimpse into this technology which will help our customers further advance their IT modernization efforts. These new features leverage a variety of advanced patents to eliminate redundant data. They are optimized to ensure the most efficient use of available hardware resources. In fact, we’ll support these improvements for all current and previous generations of Dell EMC Unity.
Dell EMC engineers designed the code to be an extension of inline compression so that applications that have compression enabled will automatically get more efficient. Best of all, deduplication will be available as a no-cost, non-disruptive upgrade. We’re really happy we can deliver the consistent performance levels that our customers expect while lowering costs

XtremIO X2 vs X1: considering bang for the buck ratio
I have promised earlier to explain how has XtremIO X2 managed to reduce cost per GB three times. From the very announcement date my customers and partners ask me if it is real. Yes, it is. I have checked it myself. So let’s do it together now.
Let’s speak English
Друзья, с сегодняшнего дня в блоге будут появляться английские переводы моих постов. Делается по просьбе иностранных коллег. Приоритетным для меня продолжает оставаться русскоязычная аудитория, потому что я знаю как нашему интернету недостает нормального ресурса про DellEMC и все такое. Так что без паники. Сначала буду писать на русском, и потом — на английском.
Dear English speaking readers.
From now on, English translations of my posts will appear in this blog. I hope you will enjoy it.
