Company strategies

Even though this week I’m on holiday, there are a couple of facts that should not be underestimated and still deserve a comment.

Fact 1: Oracle has decided, as many expected, not to pursue its partnership with HDS.

This decision is a clear sample of “Oracle-way-of-thinking” and just follows the strategy adopted so far: to keep complete control of the technology stack without having to depend on anyone as regards formulating offerings and maximizing profit.

If Oracle keeps on pushing things like exadata2 or the use of local SSD disks to store parts of a DB, then the storage to the HDS will result just increasingly sophisticated and more or less useless, at least according to our dear Larry!

HDS can definitely record this decision as bad news since Sun was the largest retailer in the world: now the Jap-Americans will be forced to make a quite difficult running start to restore its trading infrastructure, re-establish technical contacts and so on.

Sun customers find themselves with one more bitter pill to swallow: many bought from HDS to have a single supplier and are now in the unenviable situation of having two, they face an even more uncertain future with assistance and professional  services contracts to be renegotiated with HDS rather than with Sun.

The message to Sun customers gets increasingly clear: what was not fully owned by Sun is about to be buried … every allusion to the storage 6000 is not casual!

Needless to say that Sun and HDS competitors are in high spirits: Sun facing hard present times, some storage systems are rather old (the agreement is dated 10 years ago), how much time will take HDS to restructure? More than enough to make any competitor’s mouth water.

Fact 2: IBM continues to push XIV and compares it to the DS8000

I know it’s strange but this must be a strategy, but a quite strange one.

Sure, if you try to ask questions about the performance of a XIV, responses will be among the most imaginative and evasive. Try and write XIV+performance on twitter, then everyone immediately will think about a joke.

I guess that IBM is really developing its “jewel” and maybe when we see the 1.0 2.0 version we will be stunned, who knows….

The more evil ones may think there’s a subtle struggle among IBM internal departments, but really, I think that behind there must be something more … All in all the DS8000 is widely considered as dead (hardware and software architecture are quite  obsolete) and no replacement is planned .

Meanwhile, they just lay themself open to competitors in an almost paradoxical way


Strategie

Questa settimana sono in vacanza, lo ammetto, ma ci sono un paio di fatti che meritano comunque un commento e che non devono essere sottovalutati.

Fatto 1: Oracle ha deciso, come molti si aspettavano, di non portare avanti la sua partnership con HDS.

Questa decisione è in piena filosofia Oracle e quindi ricalca senza dubbi la strategia adottata fino ad ora: avere il completo controllo dello stack tecnologico senza dover dipendere da nessuno per formulare l’offerta massimizzando ogni guadagno.

In fondo è ovvio che se Oracle vuole spingere oggetti come exadata2 o usare dischi SSD locali per estendere porzioni del DB, gli storage sofisticati alla HDS sono sempre più inutili o almeno così pensa il buon Larry!!!

Dal punto di vista HDS è sicuramente una brutta notizia perchè Sun era il più grande rivenditore al mondo: ora i Giappo-Americani saranno costretti a fare una rincorsa non da ridere per ripristinare tutti i rapporti commerciali, ristabilire i contatti tecnici e così via.

Dal punto di vista dei clienti Sun è un’altra polpetta amara da dover digerire: molti di questi avevano comprato HDS per avere un solo fornitore senza doversi preoccupare di chi faceva cosa e ora sono nella spiacevole situazione di avere comunque due fornitori e un futuro sicuramente più incerto di prima, anche solo per la questione di dover rinegoziare i contratti di assistenza e servizi professionali con HDS invece che con Sun.

Il messaggio per i clienti Sun è sempre più chiaro: se una cosa non era di completa proprietà di Sun sta per essere sepolta… ogni allusione agli storage 6000 non è casuale!

Dal punto di vista dei Concorrenti di Sun e HDS c’è invece una certa euforia (euforia è un eufemismo ovviamente), il momento non felice di Sun, gli storage che in certi casi sono un po vecchiotti (l’accordo esisteva da 10 anni) e il tempo che HDS ci metterà a riprendere le fila stanno facendo venire l’acquolina in bocca a tutti!!!

Fatto 2: IBM continua a spingere XIV e lo paragona al DS8000

Lo so è strano ma anche questa deve essere una strategia, strana ma pur sempre una strategia.

Certo, se provi a fare domande specifiche sulle performance di un XIV le risposte sono fra le più fantasiose ed evasive del mondo, se provi a scrivere XIV+performance su twitter tutti pensano subito a qualche battuta di spirito, ma si vede che IBM sta sviluppando il suo “gioiellino” e forse quando potremo vedere la versione 1.0 2.0 rimarremo tutti di stucco, chissà.

I più maligni pensano ad una qualche lotta intestina fra le varie divisioni di IBM ma, in verità, penso che dietro ci debba essere qualche cosa di più… in fondo il DS8000 lo danno tutti per morto (architettura hardware e software ormai obsoleti) e non sembra esserci un sostituto a breve.

Però, intanto, stanno porgendo il fianco a i concorrenti in maniera quasi paradossale, ;-)

The best space guarantee program

After NetApp and Pillar,  3Par and HDS have now their “space guarantee” programs, but not EMC!

In the last days I saw a lot of chattering about this argument from many sources (you can find some links here, here, here and one from EMC here).

Space guarantee programs are only marketing campaigns to lure customers with fireworks and not with real substance.

Some of these programs have a lot of fine prints and clauses that look like this: “…The 50 percent guarantee is for the raw storage capacity for migrating from third party RAID-1 source environments to dynamically provisioned RAID-5 target environments. For any third party RAID-5 environment, Hitachi Data Systems will guarantee a 20 percent storage capacity reduction. …” :-D  (here the complete press-release from HDS).

So if you migrate your DB LUNs from RAID1 to RAID5 thin provisioned you can save space but no guarantees about performance! it seems more a well packaged and legalized fraud than a real opportunity for the customers!

Now I would like to show how my space (and performance) guarantee program works, a recent success case with Compellent.

My Space (and performance) guarantee program:

Compellent Storage Center with its Automated tiered storage (Data Progression), Thin provisioning (Dynamic capacity), space and performance efficient snapshot (instant replays) features may save you a lot of space, grant IOPS and big savings without any more or less hidden clause.

One of our Compellent’s customers (SCM Group) acquired their first Compellent Storage Center more than one year ago and they migrated some of their data to it, one year after (it took quite a bit to test the whole solution in production about support, real different workload, management, etc.) they then decided to move all their contents from an old HDS AMS 500  to Compellent!

The HDS was configured with a total of 1 controllers tray + 8 disk trays as follow:

  • 2 trays  300GB/10K : 6.6TB allocable capacity;
  • 4 trays 146GB/10K : 6.5TB allocable capacity;
  • 3 trays 146GB/15K : 4.9TB allocable capcity;

All the disks were configured in RAID5 (6D+1P, 1 spare per tray).

TOTALS

  • RAW disks capacity (excluding spares) is about 21TB;
  • Theoretical allocable capacity was 18TBs;
  • Really allocated for usage was 14TBs, due to shadow images (LUN clones);
  • Really used was 12,5TB!!! (near an half of raw);

We did a complete analysis of their needs and summarized the findings in these two following graphs (click on pictures for a full size view):

iops

You can easily draw two important conclusions:

  1. The space used is high: nearly 80% of usable space;
  2. The real iops deliverd are not a lot (99th percentile is 4059): no wide striping.

Well, with these information and forecasted growth in our mind we designed the best solution for the customer (not on the basis of a unrealistic marketing program):

The results are the following:

  • 135 FC disks were replaced by only 38 300GB/15K FC DISKS: less than one third!
  • To achieve new space requirements (present + 30% forecast growth) we added 16 1TB/SATA disks!
  • + 7000 measured IOPS from the Compellent upgraded (thanks to fast track and data progression), + 72% than HDS!
  • 22.7TB of allocable space, much more usable than what was allocated on HDS, thank to Instant Replays!
  • The Array is SSD ready (added more backend loops and some slots are free to accomodate some SSD disks in near future)!
  • Space usage down to 12 Rack Units from 27!
  • Huge energy savings (4 trays compared to 8 trays + 1 controller), something like 6KW (including cooling)!

And last, but not least: if we break up the cost the customer had to face for the whole operation into what covered the same space/performance they already had and what covered the increase in space/performance, well, the first part was the very same needed to just sustain the old storage (maintenance + power/cooling dissavings), all in all what they payed more for was only what they got more!

This is the best NON Marketing space (and IOPS) guarantee program I know, what do you think about it?
